-.TH curl 1 "16 Dec 2016" "Curl 7.52.0" "Curl Manual"
-.SH NAME
-curl \- transfer a URL
-.SH SYNOPSIS
-.B curl [options]
-.I [URL...]
-.SH DESCRIPTION
-.B curl
-is a tool to transfer data from or to a server, using one of the supported
-protocols (DICT, FILE, FTP, FTPS, GOPHER, HTTP, HTTPS, IMAP, IMAPS, LDAP,
-LDAPS, POP3, POP3S, RTMP, RTSP, SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET
-and TFTP). The command is designed to work without user interaction.
-
-curl offers a busload of useful tricks like proxy support, user
-authentication, FTP upload, HTTP post, SSL connections, cookies, file transfer
-resume, Metalink, and more. As you will see below, the number of features will
-make your head spin!
-
-curl is powered by libcurl for all transfer-related features. See
-\fIlibcurl(3)\fP for details.
-.SH URL
-The URL syntax is protocol-dependent. You'll find a detailed description in
-RFC 3986.
-
-You can specify multiple URLs or parts of URLs by writing part sets within
-braces as in:
-
- http://site.{one,two,three}.com
-
-or you can get sequences of alphanumeric series by using [] as in:
-
- ftp://ftp.example.com/file[1-100].txt
-
- ftp://ftp.example.com/file[001-100].txt (with leading zeros)
-
- ftp://ftp.example.com/file[a-z].txt
-
-Nested sequences are not supported, but you can use several ones next to each
-other:
-
- http://example.com/archive[1996-1999]/vol[1-4]/part{a,b,c}.html
-
-You can specify any amount of URLs on the command line. They will be fetched
-in a sequential manner in the specified order.
-
-You can specify a step counter for the ranges to get every Nth number or
-letter:
-
- http://example.com/file[1-100:10].txt
-
- http://example.com/file[a-z:2].txt
-
-When using [] or {} sequences when invoked from a command line prompt, you
-probably have to put the full URL within double quotes to avoid the shell from
-interfering with it. This also goes for other characters treated special, like
-for example '&', '?' and '*'.
-
-Provide the IPv6 zone index in the URL with an escaped percentage sign and the
-interface name. Like in
-
- http://[fe80::3%25eth0]/
-
-If you specify URL without protocol:// prefix, curl will attempt to guess what
-protocol you might want. It will then default to HTTP but try other protocols
-based on often-used host name prefixes. For example, for host names starting
-with "ftp." curl will assume you want to speak FTP.
-
-curl will do its best to use what you pass to it as a URL. It is not trying to
-validate it as a syntactically correct URL by any means but is instead
-\fBvery\fP liberal with what it accepts.
-
-curl will attempt to re-use connections for multiple file transfers, so that
-getting many files from the same server will not do multiple connects /
-handshakes. This improves speed. Of course this is only done on files
-specified on a single command line and cannot be used between separate curl
-invokes.
-.SH "PROGRESS METER"
-curl normally displays a progress meter during operations, indicating the
-amount of transferred data, transfer speeds and estimated time left, etc. The
-progress meter displays number of bytes and the speeds are in bytes per
-second. The suffixes (k, M, G, T, P) are 1024 based. For example 1k is 1024
-bytes. 1M is 1048576 bytes.
-
-curl displays this data to the terminal by default, so if you invoke curl to
-do an operation and it is about to write data to the terminal, it
-\fIdisables\fP the progress meter as otherwise it would mess up the output
-mixing progress meter and response data.
-
-If you want a progress meter for HTTP POST or PUT requests, you need to
-redirect the response output to a file, using shell redirect (>), \fI-o,
--output\fP or
-similar.
-
-It is not the same case for FTP upload as that operation does not spit out
-any response data to the terminal.
-
-If you prefer a progress "bar" instead of the regular meter, \fI-#,
--progress-bar\fP is
-your friend. You can also disable the progress meter completely with the
-\fI-s, --silent\fP option.
-.SH OPTIONS
-Options start with one or two dashes. Many of the options require an
-additional value next to them.
-
-The short "single-dash" form of the options, -d for example, may be used with
-or without a space between it and its value, although a space is a recommended
-separator. The long "double-dash" form, \fI-d, --data\fP for example, requires
a space
-between it and its value.
-
-Short version options that don't need any additional values can be used
-immediately next to each other, like for example you can specify all the
-options -O, -L and -v at once as -OLv.
-
-In general, all boolean options are enabled with --\fBoption\fP and yet again
-disabled with --\fBno-\fPoption. That is, you use the exact same option name
-but prefix it with "no-". However, in this list we mostly only list and show
-the --option version of them. (This concept with --no options was added in
-7.19.0. Previously most options were toggled on/off on repeated use of the
-same command line option.)
-.IP "--abstract-unix-socket <path>"
-(HTTP) Connect through an abstract Unix domain socket, instead of using the
network.
-Note: netstat shows the path of an abstract socket prefixed with '@', however
-the <path> argument should not have this leading character.
-
-Added in 7.53.0.
-.IP "--anyauth"
-(HTTP) Tells curl to figure out authentication method by itself, and use the
most
-secure one the remote site claims to support. This is done by first doing a
-request and checking the response-headers, thus possibly inducing an extra
-network round-trip. This is used instead of setting a specific authentication
-method, which you can do with \fI--basic\fP, \fI--digest\fP, \fI--ntlm\fP, and
\fI--negotiate\fP.
-
-Using \fI--anyauth\fP is not recommended if you do uploads from stdin, since
it may
-require data to be sent twice and then the client must be able to rewind. If
-the need should arise when uploading from stdin, the upload operation will
-fail.
-
-Used together with \fI-u, --user\fP.
-
-See also \fI--proxy-anyauth\fP and \fI--basic\fP and \fI--digest\fP.
-.IP "-a, --append"
-(FTP SFTP) When used in an upload, this makes curl append to the target file
instead of
-overwriting it. If the remote file doesn't exist, it will be created. Note
-that this flag is ignored by some SFTP servers (including OpenSSH).
-.IP "--basic"
-(HTTP) Tells curl to use HTTP Basic authentication with the remote host. This
is the
-default and this option is usually pointless, unless you use it to override a
-previously set option that sets a different authentication method (such as
-\fI--ntlm\fP, \fI--digest\fP, or \fI--negotiate\fP).
-
-Used together with \fI-u, --user\fP.
-
-See also \fI--proxy-basic\fP.
-.IP "--cacert <CA certificate>"
-(TLS) Tells curl to use the specified certificate file to verify the peer. The
file
-may contain multiple CA certificates. The certificate(s) must be in PEM
-format. Normally curl is built to use a default file for this, so this option
-is typically used to alter that default file.
-
-curl recognizes the environment variable named 'CURL_CA_BUNDLE' if it is
-set, and uses the given path as a path to a CA cert bundle. This option
-overrides that variable.
-
-The windows version of curl will automatically look for a CA certs file named
-\'curl-ca-bundle.crt\', either in the same directory as curl.exe, or in the
-Current Working Directory, or in any folder along your PATH.
-
-If curl is built against the NSS SSL library, the NSS PEM PKCS#11 module
-(libnsspem.so) needs to be available for this option to work properly.
-
-(iOS and macOS only) If curl is built against Secure Transport, then this
-option is supported for backward compatibility with other SSL engines, but it
-should not be set. If the option is not set, then curl will use the
-certificates in the system and user Keychain to verify the peer, which is the
-preferred method of verifying the peer's certificate chain.
-
-If this option is used several times, the last one will be used.
-.IP "--capath <dir>"
-(TLS) Tells curl to use the specified certificate directory to verify the
-peer. Multiple paths can be provided by separating them with ":" (e.g.
-\&"path1:path2:path3"). The certificates must be in PEM format, and if curl is
-built against OpenSSL, the directory must have been processed using the
-c_rehash utility supplied with OpenSSL. Using \fI--capath\fP can allow
-OpenSSL-powered curl to make SSL-connections much more efficiently than using
-\fI--cacert\fP if the --cacert file contains many CA certificates.
-
-If this option is set, the default capath value will be ignored, and if it is
-used several times, the last one will be used.
-.IP "--cert-status"
-(TLS) Tells curl to verify the status of the server certificate by using the
-Certificate Status Request (aka. OCSP stapling) TLS extension.
-
-If this option is enabled and the server sends an invalid (e.g. expired)
-response, if the response suggests that the server certificate has been
revoked,
-or no response at all is received, the verification fails.
-
-This is currently only implemented in the OpenSSL, GnuTLS and NSS backends.
-
-Added in 7.41.0.
-.IP "--cert-type <type>"
-(TLS) Tells curl what certificate type the provided certificate is in. PEM,
DER and
-ENG are recognized types. If not specified, PEM is assumed.
-
-If this option is used several times, the last one will be used.
-
-See also \fI-E, --cert\fP and \fI--key\fP and \fI--key-type\fP.
-.IP "-E, --cert <certificate[:password]>"
-(TLS) Tells curl to use the specified client certificate file when getting a
file
-with HTTPS, FTPS or another SSL-based protocol. The certificate must be in
-PKCS#12 format if using Secure Transport, or PEM format if using any other
-engine. If the optional password isn't specified, it will be queried for on
-the terminal. Note that this option assumes a \&"certificate" file that is the
-private key and the client certificate concatenated! See \fI-E, --cert\fP and
\fI--key\fP to
-specify them independently.
-
-If curl is built against the NSS SSL library then this option can tell
-curl the nickname of the certificate to use within the NSS database defined
-by the environment variable SSL_DIR (or by default /etc/pki/nssdb). If the
-NSS PEM PKCS#11 module (libnsspem.so) is available then PEM files may be
-loaded. If you want to use a file from the current directory, please precede
-it with "./" prefix, in order to avoid confusion with a nickname. If the
-nickname contains ":", it needs to be preceded by "\\" so that it is not
-recognized as password delimiter. If the nickname contains "\\", it needs to
-be escaped as "\\\\" so that it is not recognized as an escape character.
-
-(iOS and macOS only) If curl is built against Secure Transport, then the
-certificate string can either be the name of a certificate/private key in the
-system or user keychain, or the path to a PKCS#12-encoded certificate and
-private key. If you want to use a file from the current directory, please
-precede it with "./" prefix, in order to avoid confusion with a nickname.
-
-If this option is used several times, the last one will be used.
-
-See also \fI--cert-type\fP and \fI--key\fP and \fI--key-type\fP.
-.IP "--ciphers <list of ciphers>"
-(TLS) Specifies which ciphers to use in the connection. The list of ciphers
must
-specify valid ciphers. Read up on SSL cipher list details on this URL:
-
- https://curl.haxx.se/docs/ssl-ciphers.html
-
-If this option is used several times, the last one will be used.
-.IP "--compressed"
-(HTTP) Request a compressed response using one of the algorithms curl
supports, and
-save the uncompressed document. If this option is used and the server sends
-an unsupported encoding, curl will report an error.
-.IP "-K, --config <file>"
-Specify which config file to read curl arguments from. The config file is a
-text file in which command line arguments can be written which then will be
-used as if they were written on the actual command line.
-
-Options and their parameters must be specified on the same config file line,
-separated by whitespace, colon, or the equals sign. Long option names can
-optionally be given in the config file without the initial double dashes and
-if so, the colon or equals characters can be used as separators. If the option
-is specified with one or two dashes, there can be no colon or equals character
-between the option and its parameter.
-
-If the parameter is to contain whitespace, the parameter must be enclosed
-within quotes. Within double quotes, the following escape sequences are
-available: \\\\, \\", \\t, \\n, \\r and \\v. A backslash preceding any other
-letter is ignored. If the first column of a config line is a '#' character,
-the rest of the line will be treated as a comment. Only write one option per
-physical line in the config file.
-
-Specify the filename to \fI-K, --config\fP as '-' to make curl read the file
from stdin.
-
-Note that to be able to specify a URL in the config file, you need to specify
-it using the \fI--url\fP option, and not by simply writing the URL on its own
-line. So, it could look similar to this:
-
-url = "https://curl.haxx.se/docs/";
-
-When curl is invoked, it always (unless \fI-q, --disable\fP is used) checks
for a
-default config file and uses it if found. The default config file is checked
-for in the following places in this order:
-
-1) curl tries to find the "home dir": It first checks for the CURL_HOME and
-then the HOME environment variables. Failing that, it uses getpwuid() on
-Unix-like systems (which returns the home dir given the current user in your
-system). On Windows, it then checks for the APPDATA variable, or as a last
-resort the '%USERPROFILE%\\Application Data'.
-
-2) On windows, if there is no _curlrc file in the home dir, it checks for one
-in the same dir the curl executable is placed. On Unix-like systems, it will
-simply try to load .curlrc from the determined home dir.
-
-.nf
-# --- Example file ---
-# this is a comment
-url = "example.com"
-output = "curlhere.html"
-user-agent = "superagent/1.0"
-
-# and fetch another URL too
-url = "example.com/docs/manpage.html"
--O
-referer = "http://nowhereatall.example.com/";
-# --- End of example file ---
-.fi
-
-This option can be used multiple times to load multiple config files.
-.IP "--connect-timeout <seconds>"
-Maximum time in seconds that you allow curl's connection to take. This only
-limits the connection phase, so if curl connects within the given period it
-will continue - if not it will exit. Since version 7.32.0, this option
-accepts decimal values.
-
-If this option is used several times, the last one will be used.
-
-See also \fI-m, --max-time\fP.
-.IP "--connect-to <HOST1:PORT1:HOST2:PORT2>"
-
-For a request to the given HOST:PORT pair, connect to
-CONNECT-TO-HOST:CONNECT-TO-PORT instead. This option is suitable to direct
-requests at a specific server, e.g. at a specific cluster node in a cluster of
-servers. This option is only used to establish the network connection. It
-does NOT affect the hostname/port that is used for TLS/SSL (e.g. SNI,
-certificate verification) or for the application protocols. "host" and "port"
-may be the empty string, meaning "any host/port". "connect-to-host" and
-"connect-to-port" may also be the empty string, meaning "use the request's
-original host/port".
-
-This option can be used many times to add many connect rules.
-
-See also \fI--resolve\fP and \fI-H, --header\fP. Added in 7.49.0.
-.IP "-C, --continue-at <offset>"
-Continue/Resume a previous file transfer at the given offset. The given offset
-is the exact number of bytes that will be skipped, counting from the beginning
-of the source file before it is transferred to the destination. If used with
-uploads, the FTP server command SIZE will not be used by curl.
-
-Use "-C -" to tell curl to automatically find out where/how to resume the
-transfer. It then uses the given output/input files to figure that out.
-
-If this option is used several times, the last one will be used.
-
-See also \fI-r, --range\fP.
-.IP "-c, --cookie-jar <filename>"
-(HTTP) Specify to which file you want curl to write all cookies after a
completed
-operation. Curl writes all cookies from its in-memory cookie storage to the
-given file at the end of operations. If no cookies are known, no data will be
-written. The file will be written using the Netscape cookie file format. If
-you set the file name to a single dash, "-", the cookies will be written to
-stdout.
-
-This command line option will activate the cookie engine that makes curl
-record and use cookies. Another way to activate it is to use the \fI-b,
--cookie\fP
-option.
-
-If the cookie jar can't be created or written to, the whole curl operation
-won't fail or even report an error clearly. Using \fI-v, --verbose\fP will get
a warning
-displayed, but that is the only visible feedback you get about this possibly
-lethal situation.
-
-If this option is used several times, the last specified file name will be
-used.
-.IP "-b, --cookie <data>"
-(HTTP) Pass the data to the HTTP server in the Cookie header. It is supposedly
-the data previously received from the server in a "Set-Cookie:" line. The
-data should be in the format "NAME1=VALUE1; NAME2=VALUE2".
-
-If no '=' symbol is used in the argument, it is instead treated as a filename
-to read previously stored cookie from. This option also activates the cookie
-engine which will make curl record incoming cookies, which may be handy if
-you're using this in combination with the \fI-L, --location\fP option or do
multiple URL
-transfers on the same invoke.
-
-The file format of the file to read cookies from should be plain HTTP headers
-(Set-Cookie style) or the Netscape/Mozilla cookie file format.
-
-The file specified with \fI-b, --cookie\fP is only used as input. No cookies
will be
-written to the file. To store cookies, use the \fI-c, --cookie-jar\fP option.
-
-Exercise caution if you are using this option and multiple transfers may
-occur. If you use the NAME1=VALUE1; format, or in a file use the Set-Cookie
-format and don't specify a domain, then the cookie is sent for any domain
-(even after redirects are followed) and cannot be modified by a server-set
-cookie. If the cookie engine is enabled and a server sets a cookie of the same
-name then both will be sent on a future transfer to that server, likely not
-what you intended. To address these issues set a domain in Set-Cookie (doing
-that will include sub domains) or use the Netscape format.
-
-If this option is used several times, the last one will be used.
-
-Users very often want to both read cookies from a file and write updated
-cookies back to a file, so using both \fI-b, --cookie\fP and \fI-c,
--cookie-jar\fP in the same
-command line is common.
-.IP "--create-dirs"
-When used in conjunction with the \fI-o, --output\fP option, curl will create
the
-necessary local directory hierarchy as needed. This option creates the dirs
-mentioned with the \fI-o, --output\fP option, nothing else. If the --output
file name
-uses no dir or if the dirs it mentions already exist, no dir will be created.
-
-To create remote directories when using FTP or SFTP, try
\fI--ftp-create-dirs\fP.
-.IP "--crlf"
-(FTP SMTP) Convert LF to CRLF in upload. Useful for MVS (OS/390).
-
-(SMTP added in 7.40.0)
-.IP "--crlfile <file>"
-(TLS) Provide a file using PEM format with a Certificate Revocation List that
may
-specify peer certificates that are to be considered revoked.
-
-If this option is used several times, the last one will be used.
-
-Added in 7.19.7.
-.IP "--data-ascii <data>"
-(HTTP) This is just an alias for \fI-d, --data\fP.
-.IP "--data-binary <data>"
-(HTTP) This posts data exactly as specified with no extra processing
whatsoever.
-
-If you start the data with the letter @, the rest should be a filename. Data
-is posted in a similar manner as \fI-d, --data\fP does, except that newlines
and
-carriage returns are preserved and conversions are never done.
-
-If this option is used several times, the ones following the first will append
-data as described in \fI-d, --data\fP.
-.IP "--data-raw <data>"
-(HTTP) This posts data similarly to \fI-d, --data\fP but without the special
-interpretation of the @ character.
-
-See also \fI-d, --data\fP. Added in 7.43.0.
-.IP "--data-urlencode <data>"
-(HTTP) This posts data, similar to the other \fI-d, --data\fP options with the
exception
-that this performs URL-encoding.
-
-To be CGI-compliant, the <data> part should begin with a \fIname\fP followed
-by a separator and a content specification. The <data> part can be passed to
-curl using one of the following syntaxes:
-.RS
-.IP "content"
-This will make curl URL-encode the content and pass that on. Just be careful
-so that the content doesn't contain any = or @ symbols, as that will then make
-the syntax match one of the other cases below!
-.IP "=content"
-This will make curl URL-encode the content and pass that on. The preceding =
-symbol is not included in the data.
-.IP "name=content"
-This will make curl URL-encode the content part and pass that on. Note that
-the name part is expected to be URL-encoded already.
-.IP "@filename"
-This will make curl load data from the given file (including any newlines),
-URL-encode that data and pass it on in the POST.
-.IP "address@hidden"
-This will make curl load data from the given file (including any newlines),
-URL-encode that data and pass it on in the POST. The name part gets an equal
-sign appended, resulting in \fIname=urlencoded-file-content\fP. Note that the
-name is expected to be URL-encoded already.
-.RE
-
-See also \fI-d, --data\fP and \fI--data-raw\fP. Added in 7.18.0.
-.IP "-d, --data <data>"
-(HTTP) Sends the specified data in a POST request to the HTTP server, in the
same way
-that a browser does when a user has filled in an HTML form and presses the
-submit button. This will cause curl to pass the data to the server using the
-content-type application/x-www-form-urlencoded. Compare to \fI-F, --form\fP.
-
-\fI--data-raw\fP is almost the same but does not have a special interpretation
of
-the @ character. To post data purely binary, you should instead use the
-\fI--data-binary\fP option. To URL-encode the value of a form field you may
use
-\fI--data-urlencode\fP.
-
-If any of these options is used more than once on the same command line, the
-data pieces specified will be merged together with a separating
-&-symbol. Thus, using '-d name=daniel -d skill=lousy' would generate a post
-chunk that looks like \&'name=daniel&skill=lousy'.
-
-If you start the data with the letter @, the rest should be a file name to
-read the data from, or - if you want curl to read the data from
-stdin. Multiple files can also be specified. Posting data from a file named
-'foobar' would thus be done with \fI-d, --data\fP @foobar. When --data is told
to read
-from a file like that, carriage returns and newlines will be stripped out. If
-you don't want the @ character to have a special interpretation use
\fI--data-raw\fP
-instead.
-
-See also \fI--data-binary\fP and \fI--data-urlencode\fP and \fI--data-raw\fP.
This option overrides \fI-F, --form\fP and \fI-I, --head\fP and \fI--upload\fP.
-.IP "--delegation <LEVEL>"
-(GSS/kerberos) Set LEVEL to tell the server what it is allowed to delegate
when it
-comes to user credentials.
-.RS
-.IP "none"
-Don't allow any delegation.
-.IP "policy"
-Delegates if and only if the OK-AS-DELEGATE flag is set in the Kerberos
-service ticket, which is a matter of realm policy.
-.IP "always"
-Unconditionally allow the server to delegate.
-.RE
-.IP "--digest"
-(HTTP) Enables HTTP Digest authentication. This is an authentication scheme
that
-prevents the password from being sent over the wire in clear text. Use this in
-combination with the normal \fI-u, --user\fP option to set user name and
password.
-
-If this option is used several times, only the first one is used.
-
-See also \fI-u, --user\fP and \fI--proxy-digest\fP and \fI--anyauth\fP. This
option overrides \fI--basic\fP and \fI--ntlm\fP and \fI--negotiate\fP.
-.IP "--disable-eprt"
-(FTP) Tell curl to disable the use of the EPRT and LPRT commands when doing
active
-FTP transfers. Curl will normally always first attempt to use EPRT, then LPRT
-before using PORT, but with this option, it will use PORT right away. EPRT and
-LPRT are extensions to the original FTP protocol, and may not work on all
-servers, but they enable more functionality in a better way than the
-traditional PORT command.
-
---eprt can be used to explicitly enable EPRT again and --no-eprt is an alias
-for \fI--disable-eprt\fP.
-
-If the server is accessed using IPv6, this option will have no effect as EPRT
-is necessary then.
-
-Disabling EPRT only changes the active behavior. If you want to switch to
-passive mode you need to not use \fI-P, --ftp-port\fP or force it with
\fI--ftp-pasv\fP.
-.IP "--disable-epsv"
-(FTP) (FTP) Tell curl to disable the use of the EPSV command when doing
passive FTP
-transfers. Curl will normally always first attempt to use EPSV before PASV,
-but with this option, it will not try using EPSV.
-
---epsv can be used to explicitly enable EPSV again and --no-epsv is an alias
-for \fI--disable-epsv\fP.
-
-If the server is an IPv6 host, this option will have no effect as EPSV is
-necessary then.
-
-Disabling EPSV only changes the passive behavior. If you want to switch to
-active mode you need to use \fI-P, --ftp-port\fP.
-.IP "-q, --disable"
-If used as the first parameter on the command line, the \fIcurlrc\fP config
-file will not be read and used. See the \fI-K, --config\fP for details on the
default
-config file search path.
-.IP "--dns-interface <interface>"
-(DNS) Tell curl to send outgoing DNS requests through <interface>. This option
is a
-counterpart to \fI--interface\fP (which does not affect DNS). The supplied
string
-must be an interface name (not an address).
-
-See also \fI--dns-ipv4-addr\fP and \fI--dns-ipv6-addr\fP.
\fI--dns-interface\fP requires that the underlying libcurl was built to support
c-ares. Added in 7.33.0.
-.IP "--dns-ipv4-addr <address>"
-(DNS) Tell curl to bind to <ip-address> when making IPv4 DNS requests, so that
-the DNS requests originate from this address. The argument should be a
-single IPv4 address.
-
-See also \fI--dns-interface\fP and \fI--dns-ipv6-addr\fP.
\fI--dns-ipv4-addr\fP requires that the underlying libcurl was built to support
c-ares. Added in 7.33.0.
-.IP "--dns-ipv6-addr <address>"
-(DNS) Tell curl to bind to <ip-address> when making IPv6 DNS requests, so that
-the DNS requests originate from this address. The argument should be a
-single IPv6 address.
-
-See also \fI--dns-interface\fP and \fI--dns-ipv4-addr\fP.
\fI--dns-ipv6-addr\fP requires that the underlying libcurl was built to support
c-ares. Added in 7.33.0.
-.IP "--dns-servers <addresses>"
-Set the list of DNS servers to be used instead of the system default.
-The list of IP addresses should be separated with commas. Port numbers
-may also optionally be given as \fI:<port-number>\fP after each IP
-address.
-
-\fI--dns-servers\fP requires that the underlying libcurl was built to support
c-ares. Added in 7.33.0.
-.IP "-D, --dump-header <filename>"
-(HTTP FTP) Write the received protocol headers to the specified file.
-
-This option is handy to use when you want to store the headers that an HTTP
-site sends to you. Cookies from the headers could then be read in a second
-curl invocation by using the \fI-b, --cookie\fP option! The \fI-c,
--cookie-jar\fP option is a
-better way to store cookies.
-
-When used in FTP, the FTP server response lines are considered being "headers"
-and thus are saved there.
-
-If this option is used several times, the last one will be used.
-
-See also \fI-o, --output\fP.
-.IP "--egd-file <file>"
-(TLS) Specify the path name to the Entropy Gathering Daemon socket. The socket
is
-used to seed the random engine for SSL connections.
-
-See also \fI--random-file\fP.
-.IP "--engine <name>"
-(TLS) Select the OpenSSL crypto engine to use for cipher operations. Use
\fI--engine\fP
-list to print a list of build-time supported engines. Note that not all (or
-none) of the engines may be available at run-time.
-.IP "--environment"
-Sets a range of environment variables, using the names the \fI-w,
--write-out\fP option
-supports, to allow easier extraction of useful information after having run
-curl.
-
-\fI--environment\fP requires that the underlying libcurl was built to support
RISC OS.
-.IP "--expect100-timeout <seconds>"
-(HTTP) Maximum time in seconds that you allow curl to wait for a 100-continue
-response when curl emits an Expects: 100-continue header in its request. By
-default curl will wait one second. This option accepts decimal values! When
-curl stops waiting, it will continue as if the response has been received.
-
-See also \fI--connect-timeout\fP. Added in 7.47.0.
-.IP "--fail-early"
-Fail and exit on first detected error.
-
-When curl is used to do multiple transfers on the command line, it will
-attempt to operate on each given URL, one by one. By default, it will ignore
-errors if there are more URLs given and the last URL's success will determine
-the error code curl returns. So early failures will be "hidden" by subsequent
-successful transfers.
-
-Using this option, curl will instead return an error on the first transfers
-that fails, independent on the amount of more URLs that are given on the
-command line. This way, no transfer failures go undetected by scripts and
-similar.
-
-This option will apply for all given URLs even if you use \fI-:, --next\fP.
-
-Added in 7.52.0.
-.IP "-f, --fail"
-(HTTP) Fail silently (no output at all) on server errors. This is mostly done
to
-better enable scripts etc to better deal with failed attempts. In normal cases
-when an HTTP server fails to deliver a document, it returns an HTML document
-stating so (which often also describes why and more). This flag will prevent
-curl from outputting that and return error 22.
-
-This method is not fail-safe and there are occasions where non-successful
-response codes will slip through, especially when authentication is involved
-(response codes 401 and 407).
-.IP "--false-start"
-(TLS) Tells curl to use false start during the TLS handshake. False start is a
mode
-where a TLS client will start sending application data before verifying the
-server's Finished message, thus saving a round trip when performing a full
-handshake.
-
-This is currently only implemented in the NSS and Secure Transport (on iOS 7.0
-or later, or OS X 10.9 or later) backends.
-
-Added in 7.42.0.
-.IP "--form-string <name=string>"
-(HTTP) Similar to \fI-F, --form\fP except that the value string for the named
parameter is used
-literally. Leading \&'@' and \&'<' characters, and the \&';type=' string in
-the value have no special meaning. Use this in preference to \fI-F, --form\fP
if
-there's any possibility that the string value may accidentally trigger the
-\&'@' or \&'<' features of \fI-F, --form\fP.
-
-See also \fI-F, --form\fP.
-.IP "-F, --form <name=content>"
-(HTTP) This lets curl emulate a filled-in form in which a user has pressed the
submit
-button. This causes curl to POST data using the Content-Type
-multipart/form-data according to RFC 2388. This enables uploading of binary
-files etc. To force the 'content' part to be a file, prefix the file name with
-an @ sign. To just get the content part from a file, prefix the file name with
-the symbol <. The difference between @ and < is then that @ makes a file get
-attached in the post as a file upload, while the < makes a text field and just
-get the contents for that text field from a file.
-
-Example: to send an image to a server, where \&'profile' is the name of the
-form-field to which portrait.jpg will be the input:
-
- curl -F address@hidden https://example.com/upload.cgi
-
-To read content from stdin instead of a file, use - as the filename. This goes
-for both @ and < constructs. Unfortunately it does not support reading the
-file from a named pipe or similar, as it needs the full size before the
-transfer starts.
-
-You can also tell curl what Content-Type to use by using 'type=', in a manner
-similar to:
-
- curl -F "address@hidden;type=text/html" example.com
-
-or
-
- curl -F "name=daniel;type=text/foo" example.com
-
-You can also explicitly change the name field of a file upload part by setting
-filename=, like this:
-
- curl -F "address@hidden;filename=nameinpost" example.com
-
-If filename/path contains ',' or ';', it must be quoted by double-quotes like:
-
- curl -F "address@hidden"localfile\\";filename=\\"nameinpost\\"" example.com
-
-or
-
- curl -F 'file=@"localfile";filename="nameinpost"' example.com
-
-Note that if a filename/path is quoted by double-quotes, any double-quote
-or backslash within the filename must be escaped by backslash.
-
-See further examples and details in the MANUAL.
-
-This option can be used multiple times.
-
-This option overrides \fI-d, --data\fP and \fI-I, --head\fP and \fI--upload\fP.
-.IP "--ftp-account <data>"
-(FTP) When an FTP server asks for "account data" after user name and password
has
-been provided, this data is sent off using the ACCT command.
-
-If this option is used several times, the last one will be used.
-
-Added in 7.13.0.
-.IP "--ftp-alternative-to-user <command>"
-(FTP) If authenticating with the USER and PASS commands fails, send this
command.
-When connecting to Tumbleweed's Secure Transport server over FTPS using a
-client certificate, using "SITE AUTH" will tell the server to retrieve the
-username from the certificate.
-
-Added in 7.15.5.
-.IP "--ftp-create-dirs"
-(FTP SFTP) When an FTP or SFTP URL/operation uses a path that doesn't
currently exist on
-the server, the standard behavior of curl is to fail. Using this option, curl
-will instead attempt to create missing directories.
-
-See also \fI--create-dirs\fP.
-.IP "--ftp-method <method>"
-(FTP) Control what method curl should use to reach a file on an FTP(S)
-server. The method argument should be one of the following alternatives:
-.RS
-.IP multicwd
-curl does a single CWD operation for each path part in the given URL. For deep
-hierarchies this means very many commands. This is how RFC 1738 says it should
-be done. This is the default but the slowest behavior.
-.IP nocwd
-curl does no CWD at all. curl will do SIZE, RETR, STOR etc and give a full
-path to the server for all these commands. This is the fastest behavior.
-.IP singlecwd
-curl does one CWD with the full target directory and then operates on the file
-\&"normally" (like in the multicwd case). This is somewhat more standards
-compliant than 'nocwd' but without the full penalty of 'multicwd'.
-.RE
-
-Added in 7.15.1.
-.IP "--ftp-pasv"
-(FTP) Use passive mode for the data connection. Passive is the internal default
-behavior, but using this option can be used to override a previous \fI-P,
--ftp-port\fP
-option.
-
-If this option is used several times, only the first one is used. Undoing an
-enforced passive really isn't doable but you must then instead enforce the
-correct \fI-P, --ftp-port\fP again.
-
-Passive mode means that curl will try the EPSV command first and then PASV,
-unless \fI--disable-epsv\fP is used.
-
-See also \fI--disable-epsv\fP. Added in 7.11.0.
-.IP "-P, --ftp-port <address>"
-(FTP) Reverses the default initiator/listener roles when connecting with FTP.
This
-option makes curl use active mode. curl then tells the server to connect back
-to the client's specified address and port, while passive mode asks the server
-to setup an IP address and port for it to connect to. <address> should be one
-of:
-.RS
-.IP interface
-i.e "eth0" to specify which interface's IP address you want to use (Unix only)
-.IP "IP address"
-i.e "192.168.10.1" to specify the exact IP address
-.IP "host name"
-i.e "my.host.domain" to specify the machine
-.IP "-"
-make curl pick the same IP address that is already used for the control
-connection
-.RE
-
-If this option is used several times, the last one will be used. Disable the
-use of PORT with \fI--ftp-pasv\fP. Disable the attempt to use the EPRT command
-instead of PORT by using \fI--disable-eprt\fP. EPRT is really PORT++.
-
-Since 7.19.5, you can append \&":[start]-[end]\&" to the right of the address,
-to tell curl what TCP port range to use. That means you specify a port range,
-from a lower to a higher number. A single number works as well, but do note
-that it increases the risk of failure since the port may not be available.
-
-See also \fI--ftp-pasv\fP and \fI--disable-eprt\fP.
-.IP "--ftp-pret"
-(FTP) Tell curl to send a PRET command before PASV (and EPSV). Certain FTP
servers,
-mainly drftpd, require this non-standard command for directory listings as
-well as up and downloads in PASV mode.
-
-Added in 7.20.0.
-.IP "--ftp-skip-pasv-ip"
-(FTP) Tell curl to not use the IP address the server suggests in its response
-to curl's PASV command when curl connects the data connection. Instead curl
-will re-use the same IP address it already uses for the control
-connection.
-
-This option has no effect if PORT, EPRT or EPSV is used instead of PASV.
-
-See also \fI--ftp-pasv\fP. Added in 7.14.2.
-.IP "--ftp-ssl-ccc-mode <active/passive>"
-(FTP) Sets the CCC mode. The passive mode will not initiate the shutdown, but
-instead wait for the server to do it, and will not reply to the shutdown from
-the server. The active mode initiates the shutdown and waits for a reply from
-the server.
-
-See also \fI--ftp-ssl-ccc\fP. Added in 7.16.2.
-.IP "--ftp-ssl-ccc"
-(FTP) Use CCC (Clear Command Channel) Shuts down the SSL/TLS layer after
-authenticating. The rest of the control channel communication will be
-unencrypted. This allows NAT routers to follow the FTP transaction. The
-default mode is passive.
-
-See also \fI--ssl\fP and \fI--ftp-ssl-ccc-mode\fP. Added in 7.16.1.
-.IP "--ftp-ssl-control"
-(FTP) Require SSL/TLS for the FTP login, clear for transfer. Allows secure
-authentication, but non-encrypted data transfers for efficiency. Fails the
-transfer if the server doesn't support SSL/TLS.
-
-Added in 7.16.0.
-.IP "-G, --get"
-When used, this option will make all data specified with \fI-d, --data\fP,
\fI--data-binary\fP
-or \fI--data-urlencode\fP to be used in an HTTP GET request instead of the POST
-request that otherwise would be used. The data will be appended to the URL
-with a '?' separator.
-
-If used in combination with \fI-I, --head\fP, the POST data will instead be
appended to
-the URL with a HEAD request.
-
-If this option is used several times, only the first one is used. This is
-because undoing a GET doesn't make sense, but you should then instead enforce
-the alternative method you prefer.
-.IP "-g, --globoff"
-This option switches off the "URL globbing parser". When you set this option,
-you can specify URLs that contain the letters {}[] without having them being
-interpreted by curl itself. Note that these letters are not normal legal URL
-contents but they should be encoded according to the URI standard.
-.IP "-I, --head"
-(HTTP FTP FILE) Fetch the headers only! HTTP-servers feature the command HEAD
which this uses
-to get nothing but the header of a document. When used on an FTP or FILE file,
-curl displays the file size and last modification time only.
-.IP "-H, --header <header>"
-(HTTP)
-Extra header to include in the request when sending HTTP to a server. You may
-specify any number of extra headers. Note that if you should add a custom
-header that has the same name as one of the internal ones curl would use, your
-externally set header will be used instead of the internal one. This allows
-you to make even trickier stuff than curl would normally do. You should not
-replace internally set headers without knowing perfectly well what you're
-doing. Remove an internal header by giving a replacement without content on
-the right side of the colon, as in: -H \&"Host:". If you send the custom
-header with no-value then its header must be terminated with a semicolon, such
-as \-H \&"X-Custom-Header;" to send "X-Custom-Header:".
-
-curl will make sure that each header you add/replace is sent with the proper
-end-of-line marker, you should thus \fBnot\fP add that as a part of the header
-content: do not add newlines or carriage returns, they will only mess things up
-for you.
-
-See also the \fI-A, --user-agent\fP and \fI-e, --referer\fP options.
-
-Starting in 7.37.0, you need \fI--proxy-header\fP to send custom headers
intended
-for a proxy.
-
-Example:
-
- curl -H "X-First-Name: Joe" http://example.com/
-
-\fBWARNING\fP: headers set with this option will be set in all requests - even
-after redirects are followed, like when told with \fI-L, --location\fP. This
can lead to
-the header being sent to other hosts than the original host, so sensitive
-headers should be used with caution combined with following redirects.
-
-This option can be used multiple times to add/replace/remove multiple headers.
-.IP "-h, --help"
-Usage help. This lists all current command line options with a short
-description.
-.IP "--hostpubmd5 <md5>"
-(SFTP SCP) Pass a string containing 32 hexadecimal digits. The string should
-be the 128 bit MD5 checksum of the remote host's public key, curl will refuse
-the connection with the host unless the md5sums match.
-
-Added in 7.17.1.
-.IP "-0, --http1.0"
-(HTTP) Tells curl to use HTTP version 1.0 instead of using its internally
preferred
-HTTP version.
-
-This option overrides \fI--http1.1\fP and \fI--http2\fP.
-.IP "--http1.1"
-(HTTP) Tells curl to use HTTP version 1.1.
-
-This option overrides \fI-0, --http1.0\fP and \fI--http2\fP. Added in 7.33.0.
-.IP "--http2-prior-knowledge"
-(HTTP) Tells curl to issue its non-TLS HTTP requests using HTTP/2 without
HTTP/1.1
-Upgrade. It requires prior knowledge that the server supports HTTP/2 straight
-away. HTTPS requests will still do HTTP/2 the standard way with negotiated
-protocol version in the TLS handshake.
-
-\fI--http2-prior-knowledge\fP requires that the underlying libcurl was built
to support HTTP/2. This option overrides \fI--http1.1\fP and \fI-0,
--http1.0\fP and \fI--http2\fP. Added in 7.49.0.
-.IP "--http2"
-(HTTP) Tells curl to use HTTP version 2.
-
-See also \fI--no-alpn\fP. \fI--http2\fP requires that the underlying libcurl
was built to support HTTP/2. This option overrides \fI--http1.1\fP and \fI-0,
--http1.0\fP and \fI--http2-prior-knowledge\fP. Added in 7.33.0.
-.IP "--ignore-content-length"
-(FTP HTTP) For HTTP, Ignore the Content-Length header. This is particularly
useful for
-servers running Apache 1.x, which will report incorrect Content-Length for
-files larger than 2 gigabytes.
-
-For FTP (since 7.46.0), skip the RETR command to figure out the size before
-downloading a file.
-.IP "-i, --include"
-Include the HTTP-header in the output. The HTTP-header includes things like
-server-name, date of the document, HTTP-version and more...
-
-See also \fI-v, --verbose\fP.
-.IP "-k, --insecure"
-(TLS) This option explicitly allows curl to perform "insecure" SSL connections
and
-transfers. All SSL connections are attempted to be made secure by using the CA
-certificate bundle installed by default. This makes all connections considered
-\&"insecure" fail unless \fI-k, --insecure\fP is used.
-
-See this online resource for further details:
- https://curl.haxx.se/docs/sslcerts.html
-.IP "--interface <name>"
-
-Perform an operation using a specified interface. You can enter interface
-name, IP address or host name. An example could look like:
-
- curl --interface eth0:1 https://www.example.com/
-
-If this option is used several times, the last one will be used.
-
-See also \fI--dns-interface\fP.
-.IP "-4, --ipv4"
-This option tells curl to resolve names to IPv4 addresses only, and not for
-example try IPv6.
-
-See also \fI--http1.1\fP and \fI--http2\fP. This option overrides \fI-6,
--ipv6\fP.
-.IP "-6, --ipv6"
-This option tells curl to resolve names to IPv6 addresses only, and not for
-example try IPv4.
-
-See also \fI--http1.1\fP and \fI--http2\fP. This option overrides \fI-6,
--ipv6\fP.
-.IP "-j, --junk-session-cookies"
-(HTTP) When curl is told to read cookies from a given file, this option will
make it
-discard all "session cookies". This will basically have the same effect as if
-a new session is started. Typical browsers always discard session cookies when
-they're closed down.
-
-See also \fI-b, --cookie\fP and \fI-c, --cookie-jar\fP.
-.IP "--keepalive-time <seconds>"
-This option sets the time a connection needs to remain idle before sending
-keepalive probes and the time between individual keepalive probes. It is
-currently effective on operating systems offering the TCP_KEEPIDLE and
-TCP_KEEPINTVL socket options (meaning Linux, recent AIX, HP-UX and more). This
-option has no effect if \fI--no-keepalive\fP is used.
-
-If this option is used several times, the last one will be used. If
-unspecified, the option defaults to 60 seconds.
-
-Added in 7.18.0.
-.IP "--key-type <type>"
-(TLS) Private key file type. Specify which type your \fI--key\fP provided
private key
-is. DER, PEM, and ENG are supported. If not specified, PEM is assumed.
-
-If this option is used several times, the last one will be used.
-.IP "--key <key>"
-(TLS SSH) Private key file name. Allows you to provide your private key in
this separate
-file. For SSH, if not specified, curl tries the following candidates in order:
-'~/.ssh/id_rsa', '~/.ssh/id_dsa', './id_rsa', './id_dsa'.
-
-If this option is used several times, the last one will be used.
-.IP "--krb <level>"
-(FTP) Enable Kerberos authentication and use. The level must be entered and
should
-be one of 'clear', 'safe', 'confidential', or 'private'. Should you use a
-level that is not one of these, 'private' will instead be used.
-
-If this option is used several times, the last one will be used.
-
-\fI--krb\fP requires that the underlying libcurl was built to support Kerberos.
-.IP "--libcurl <file>"
-Append this option to any ordinary curl command line, and you will get a
-libcurl-using C source code written to the file that does the equivalent
-of what your command-line operation does!
-
-If this option is used several times, the last given file name will be
-used.
-
-Added in 7.16.1.
-.IP "--limit-rate <speed>"
-Specify the maximum transfer rate you want curl to use - for both downloads
-and uploads. This feature is useful if you have a limited pipe and you'd like
-your transfer not to use your entire bandwidth. To make it slower than it
-otherwise would be.
-
-The given speed is measured in bytes/second, unless a suffix is appended.
-Appending 'k' or 'K' will count the number as kilobytes, 'm' or M' makes it
-megabytes, while 'g' or 'G' makes it gigabytes. Examples: 200K, 3m and 1G.
-
-If you also use the \fI-Y, --speed-limit\fP option, that option will take
precedence and
-might cripple the rate-limiting slightly, to help keeping the speed-limit
-logic working.
-
-If this option is used several times, the last one will be used.
-.IP "-l, --list-only"
-(FTP POP3) (FTP)
-When listing an FTP directory, this switch forces a name-only view. This is
-especially useful if the user wants to machine-parse the contents of an FTP
-directory since the normal directory view doesn't use a standard look or
-format. When used like this, the option causes a NLST command to be sent to
-the server instead of LIST.
-
-Note: Some FTP servers list only files in their response to NLST; they do not
-include sub-directories and symbolic links.
-
-(POP3)
-When retrieving a specific email from POP3, this switch forces a LIST command
-to be performed instead of RETR. This is particularly useful if the user wants
-to see if a specific message id exists on the server and what size it is.
-
-Note: When combined with \fI-X, --request\fP, this option can be used to send
an UIDL
-command instead, so the user may use the email's unique identifier rather than
-it's message id to make the request.
-
-Added in 7.21.5.
-.IP "--local-port <num/range>"
-Set a preferred single number or range (FROM-TO) of local port numbers to use
-for the connection(s). Note that port numbers by nature are a scarce resource
-that will be busy at times so setting this range to something too narrow might
-cause unnecessary connection setup failures.
-
-Added in 7.15.2.
-.IP "--location-trusted"
-(HTTP) Like \fI-L, --location\fP, but will allow sending the name + password
to all hosts that
-the site may redirect to. This may or may not introduce a security breach if
-the site redirects you to a site to which you'll send your authentication info
-(which is plaintext in the case of HTTP Basic authentication).
-
-See also \fI-u, --user\fP.
-.IP "-L, --location"
-(HTTP) If the server reports that the requested page has moved to a different
-location (indicated with a Location: header and a 3XX response code), this
-option will make curl redo the request on the new place. If used together with
-\fI-i, --include\fP or \fI-I, --head\fP, headers from all requested pages will
be shown. When
-authentication is used, curl only sends its credentials to the initial
-host. If a redirect takes curl to a different host, it won't be able to
-intercept the user+password. See also \fI--location-trusted\fP on how to change
-this. You can limit the amount of redirects to follow by using the
-\fI--max-redirs\fP option.
-
-When curl follows a redirect and the request is not a plain GET (for example
-POST or PUT), it will do the following request with a GET if the HTTP response
-was 301, 302, or 303. If the response code was any other 3xx code, curl will
-re-send the following request using the same unmodified method.
-
-You can tell curl to not change the non-GET request method to GET after a 30x
-response by using the dedicated options for that: \fI--post301\fP,
\fI--post302\fP and
-\fI--post303\fP.
-.IP "--login-options <options>"
-(IMAP POP3 SMTP) Specify the login options to use during server authentication.
-
-You can use the login options to specify protocol specific options that may
-be used during authentication. At present only IMAP, POP3 and SMTP support
-login options. For more information about the login options please see
-RFC 2384, RFC 5092 and IETF draft draft-earhart-url-smtp-00.txt
-
-If this option is used several times, the last one will be used.
-
-Added in 7.34.0.
-.IP "--mail-auth <address>"
-(SMTP) Specify a single address. This will be used to specify the
authentication
-address (identity) of a submitted message that is being relayed to another
-server.
-
-See also \fI--mail-rcpt\fP and \fI--mail-from\fP. Added in 7.25.0.
-.IP "--mail-from <address>"
-(SMTP) Specify a single address that the given mail should get sent from.
-
-See also \fI--mail-rcpt\fP and \fI--mail-auth\fP. Added in 7.20.0.
-.IP "--mail-rcpt <address>"
-(SMTP) Specify a single address, user name or mailing list name. Repeat this
-option several times to send to multiple recipients.
-
-When performing a mail transfer, the recipient should specify a valid email
-address to send the mail to.
-
-When performing an address verification (VRFY command), the recipient should be
-specified as the user name or user name and domain (as per Section 3.5 of
-RFC5321). (Added in 7.34.0)
-
-When performing a mailing list expand (EXPN command), the recipient should be
-specified using the mailing list name, such as "Friends" or "London-Office".
-(Added in 7.34.0)
-
-Added in 7.20.0.
-.IP "-M, --manual"
-Manual. Display the huge help text.
-.IP "--max-filesize <bytes>"
-Specify the maximum size (in bytes) of a file to download. If the file
-requested is larger than this value, the transfer will not start and curl will
-return with exit code 63.
-
-\fBNOTE:\fP The file size is not always known prior to download, and for such
-files this option has no effect even if the file transfer ends up being larger
-than this given limit. This concerns both FTP and HTTP transfers.
-
-See also \fI--limit-rate\fP.
-.IP "--max-redirs <num>"
-(HTTP) Set maximum number of redirection-followings allowed. When \fI-L,
--location\fP is used,
-is used to prevent curl from following redirections \&"in absurdum". By
-default, the limit is set to 50 redirections. Set this option to -1 to make it
-unlimited.
-
-If this option is used several times, the last one will be used.
-.IP "-m, --max-time <time>"
-Maximum time in seconds that you allow the whole operation to take. This is
-useful for preventing your batch jobs from hanging for hours due to slow
-networks or links going down. Since 7.32.0, this option accepts decimal
-values, but the actual timeout will decrease in accuracy as the specified
-timeout increases in decimal precision.
-
-If this option is used several times, the last one will be used.
-
-See also \fI--connect-timeout\fP.
-.IP "--metalink"
-This option can tell curl to parse and process a given URI as Metalink file
-(both version 3 and 4 (RFC 5854) are supported) and make use of the mirrors
-listed within for failover if there are errors (such as the file or server not
-being available). It will also verify the hash of the file after the download
-completes. The Metalink file itself is downloaded and processed in memory and
-not stored in the local file system.
-
-Example to use a remote Metalink file:
-
- curl --metalink http://www.example.com/example.metalink
-
-To use a Metalink file in the local file system, use FILE protocol (file://):
-
- curl --metalink file://example.metalink
-
-Please note that if FILE protocol is disabled, there is no way to use a local
-Metalink file at the time of this writing. Also note that if \fI--metalink\fP
and
-\fI-i, --include\fP are used together, --include will be ignored. This is
because
-including headers in the response will break Metalink parser and if the
-headers are included in the file described in Metalink file, hash check will
-fail.
-
-
-\fI--metalink\fP requires that the underlying libcurl was built to support
metalink. Added in 7.27.0.
-.IP "--negotiate"
-(HTTP) Enables Negotiate (SPNEGO) authentication.
-
-This option requires a library built with GSS-API or SSPI support. Use
-\fI-V, --version\fP to see if your curl supports GSS-API/SSPI or SPNEGO.
-
-When using this option, you must also provide a fake \fI-u, --user\fP option
to activate
-the authentication code properly. Sending a '-u :' is enough as the user name
-and password from the \fI-u, --user\fP option aren't actually used.
-
-If this option is used several times, only the first one is used.
-
-See also \fI--basic\fP and \fI--ntlm\fP and \fI--anyauth\fP and
\fI--proxy-negotiate\fP.
-.IP "--netrc-file <filemame>"
-This option is similar to \fI-n, --netrc\fP, except that you provide the path
(absolute
-or relative) to the netrc file that Curl should use. You can only specify one
-netrc file per invocation. If several \fI--netrc-file\fP options are provided,
-the last one will be used.
-
-It will abide by \fI--netrc-optional\fP if specified.
-
-This option overrides \fI-n, --netrc\fP. Added in 7.21.5.
-.IP "--netrc-optional"
-Very similar to \fI-n, --netrc\fP, but this option makes the .netrc usage
\fBoptional\fP
-and not mandatory as the \fI-n, --netrc\fP option does.
-
-See also \fI--netrc-file\fP. This option overrides \fI-n, --netrc\fP.
-.IP "-n, --netrc"
-Makes curl scan the \fI.netrc\fP (\fI_netrc\fP on Windows) file in the user's
-home directory for login name and password. This is typically used for FTP on
-Unix. If used with HTTP, curl will enable user authentication. See
-\fInetrc(5)\fP \fIftp(1)\fP for details on the file format. Curl will not
-complain if that file doesn't have the right permissions (it should not be
-either world- or group-readable). The environment variable "HOME" is used to
-find the home directory.
-
-A quick and very simple example of how to setup a \fI.netrc\fP to allow curl
-to FTP to the machine host.domain.com with user name \&'myself' and password
-\&'secret' should look similar to:
-
-.B "machine host.domain.com login myself password secret"
-.IP "-:, --next"
-Tells curl to use a separate operation for the following URL and associated
-options. This allows you to send several URL requests, each with their own
-specific options, for example, such as different user names or custom requests
-for each.
-
-\fI-:, --next\fP will reset all local options and only global ones will have
their
-values survive over to the operation following the \fI-:, --next\fP
instruction. Global
-options include \fI-v, --verbose\fP, \fI--trace\fP, \fI--trace-ascii\fP and
\fI--fail-early\fP.
-
-For example, you can do both a GET and a POST in a single command line:
-
- curl www1.example.com --next -d postthis www2.example.com
-
-Added in 7.36.0.
-.IP "--no-alpn"
-(HTTPS) Disable the ALPN TLS extension. ALPN is enabled by default if libcurl
was built
-with an SSL library that supports ALPN. ALPN is used by a libcurl that supports
-HTTP/2 to negotiate HTTP/2 support with the server during https sessions.
-
-See also \fI--no-npn\fP and \fI--http2\fP. \fI--no-alpn\fP requires that the
underlying libcurl was built to support TLS. Added in 7.36.0.
-.IP "-N, --no-buffer"
-Disables the buffering of the output stream. In normal work situations, curl
-will use a standard buffered output stream that will have the effect that it
-will output the data in chunks, not necessarily exactly when the data arrives.
-Using this option will disable that buffering.
-
-Note that this is the negated option name documented. You can thus use
---buffer to enforce the buffering.
-.IP "--no-keepalive"
-Disables the use of keepalive messages on the TCP connection. curl otherwis
-enables them by default.
-
-Note that this is the negated option name documented. You can thus use
---keepalive to enforce keepalive.
-.IP "--no-npn"
-(HTTPS) Disable the NPN TLS extension. NPN is enabled by default if libcurl
was built
-with an SSL library that supports NPN. NPN is used by a libcurl that supports
-HTTP/2 to negotiate HTTP/2 support with the server during https sessions.
-
-See also \fI--no-alpn\fP and \fI--http2\fP. \fI--no-npn\fP requires that the
underlying libcurl was built to support TLS. Added in 7.36.0.
-.IP "--no-sessionid"
-(TLS) Disable curl's use of SSL session-ID caching. By default all transfers
are
-done using the cache. Note that while nothing should ever get hurt by
-attempting to reuse SSL session-IDs, there seem to be broken SSL
-implementations in the wild that may require you to disable this in order for
-you to succeed.
-
-Note that this is the negated option name documented. You can thus use
---sessionid to enforce session-ID caching.
-
-Added in 7.16.0.
-.IP "--noproxy <no-proxy-list>"
-Comma-separated list of hosts which do not use a proxy, if one is specified.
-The only wildcard is a single * character, which matches all hosts, and
-effectively disables the proxy. Each name in this list is matched as either
-a domain which contains the hostname, or the hostname itself. For example,
-local.com would match local.com, local.com:80, and www.local.com, but not
-www.notlocal.com.
-
-Since 7.53.0, This option overrides the environment variables that disable the
-proxy. If there's an environment variable disabling a proxy, you can set
-noproxy list to \&"" to override it.
-
-Added in 7.19.4.
-.IP "--ntlm-wb"
-(HTTP) Enables NTLM much in the style \fI--ntlm\fP does, but hand over the
authentication
-to the separate binary ntlmauth application that is executed when needed.
-
-See also \fI--ntlm\fP and \fI--proxy-ntlm\fP.
-.IP "--ntlm"
-(HTTP) Enables NTLM authentication. The NTLM authentication method was
designed by
-Microsoft and is used by IIS web servers. It is a proprietary protocol,
-reverse-engineered by clever people and implemented in curl based on their
-efforts. This kind of behavior should not be endorsed, you should encourage
-everyone who uses NTLM to switch to a public and documented authentication
-method instead, such as Digest.
-
-If you want to enable NTLM for your proxy authentication, then use
-\fI--proxy-ntlm\fP.
-
-If this option is used several times, only the first one is used.
-
-See also \fI--proxy-ntlm\fP. \fI--ntlm\fP requires that the underlying libcurl
was built to support TLS. This option overrides \fI--basic\fP and
\fI--negotiated\fP and \fI--digest\fP and \fI--anyauth\fP.
-.IP "--oauth2-bearer"
-(IMAP POP3 SMTP) Specify the Bearer Token for OAUTH 2.0 server authentication.
The Bearer Token
-is used in conjunction with the user name which can be specified as part of
-the \fI--url\fP or \fI-u, --user\fP options.
-
-The Bearer Token and user name are formatted according to RFC 6750.
-
-If this option is used several times, the last one will be used.
-.IP "-o, --output <file>"
-Write output to <file> instead of stdout. If you are using {} or [] to fetch
-multiple documents, you can use '#' followed by a number in the <file>
-specifier. That variable will be replaced with the current string for the URL
-being fetched. Like in:
-
- curl http://{one,two}.example.com -o "file_#1.txt"
-
-or use several variables like:
-
- curl http://{site,host}.host[1-5].com -o "#1_#2"
-
-You may use this option as many times as the number of URLs you have. For
-example, if you specify two URLs on the same command line, you can use it like
-this:
-
- curl -o aa example.com -o bb example.net
-
-and the order of the -o options and the URLs doesn't matter, just that the
-first -o is for the first URL and so on, so the above command line can also be
-written as
-
- curl example.com example.net -o aa -o bb
-
-See also the \fI--create-dirs\fP option to create the local directories
-dynamically. Specifying the output as '-' (a single dash) will force the
-output to be done to stdout.
-
-See also \fI-O, --remote-name\fP and \fI--remote-name-all\fP and \fI-J,
--remote-header-name\fP.
-.IP "--pass <phrase>"
-(SSH TLS) Passphrase for the private key
-
-If this option is used several times, the last one will be used.
-.IP "--path-as-is"
-Tell curl to not handle sequences of /../ or /./ in the given URL
-path. Normally curl will squash or merge them according to standards but with
-this option set you tell it not to do that.
-
-Added in 7.42.0.
-.IP "--pinnedpubkey <hashes>"
-(TLS) Tells curl to use the specified public key file (or hashes) to verify the
-peer. This can be a path to a file which contains a single public key in PEM
-or DER format, or any number of base64 encoded sha256 hashes preceded by
-\'sha256//\' and separated by \';\'
-
-When negotiating a TLS or SSL connection, the server sends a certificate
-indicating its identity. A public key is extracted from this certificate and
-if it does not exactly match the public key provided to this option, curl will
-abort the connection before sending or receiving any data.
-
-PEM/DER support:
- 7.39.0: OpenSSL, GnuTLS and GSKit
- 7.43.0: NSS and wolfSSL/CyaSSL
- 7.47.0: mbedtls
- 7.49.0: PolarSSL
-sha256 support:
- 7.44.0: OpenSSL, GnuTLS, NSS and wolfSSL/CyaSSL.
- 7.47.0: mbedtls
- 7.49.0: PolarSSL
-Other SSL backends not supported.
-
-If this option is used several times, the last one will be used.
-.IP "--post301"
-(HTTP) Tells curl to respect RFC 7231/6.4.2 and not convert POST requests into
GET
-requests when following a 301 redirection. The non-RFC behaviour is ubiquitous
-in web browsers, so curl does the conversion by default to maintain
-consistency. However, a server may require a POST to remain a POST after such
-a redirection. This option is meaningful only when using \fI-L, --location\fP.
-
-See also \fI--post302\fP and \fI--post303\fP and \fI-L, --location\fP. Added
in 7.17.1.
-.IP "--post302"
-(HTTP) Tells curl to respect RFC 7231/6.4.3 and not convert POST requests into
GET
-requests when following a 302 redirection. The non-RFC behaviour is ubiquitous
-in web browsers, so curl does the conversion by default to maintain
-consistency. However, a server may require a POST to remain a POST after such
-a redirection. This option is meaningful only when using \fI-L, --location\fP.
-
-See also \fI--post301\fP and \fI--post303\fP and \fI-L, --location\fP. Added
in 7.19.1.
-.IP "--post303"
-(HTTP) Tells curl to respect RFC 7231/6.4.4 and not convert POST requests into
GET
-requests when following a 303 redirection. The non-RFC behaviour is ubiquitous
-in web browsers, so curl does the conversion by default to maintain
-consistency. However, a server may require a POST to remain a POST after such
-a redirection. This option is meaningful only when using \fI-L, --location\fP.
-
-See also \fI--post302\fP and \fI--post301\fP and \fI-L, --location\fP. Added
in 7.26.0.
-.IP "--preproxy [protocol://]host[:port]"
-Use the specified proxy before connecting to the ordinary proxy. Hence pre
-proxy. A pre proxy must be a SOCKS speaking proxy.
-
-The pre proxy string should be specified with a protocol:// prefix to specify
-alternative proxy protocols. Use socks4://, socks4a://, socks5:// or
-socks5h:// to request the specific SOCKS version to be used. No protocol
-specified will make curl default to SOCKS4.
-
-If the port number is not specified in the proxy string, it is assumed to be
-1080.
-
-User and password that might be provided in the proxy string are URL decoded
-by curl. This allows you to pass in special characters such as @ by using %40
-or pass in a colon with %3a.
-
-If this option is used several times, the last one will be used.
-
-Added in 7.52.0.
-.IP "-#, --progress-bar"
-Make curl display transfer progress as a simple progress bar instead of the
-standard, more informational, meter.
-
-This progress bar draws a single line of '#' characters across the screen and
-shows a percentage if the transfer size is known. For transfers without a
-known size, it will instead output one '#' character for every 1024 bytes
-transferred.
-.IP "--proto-default <protocol>"
-Tells curl to use \fIprotocol\fP for any URL missing a scheme name.
-
-Example:
-
- curl --proto-default https ftp.mozilla.org
-
-An unknown or unsupported protocol causes error
-\fICURLE_UNSUPPORTED_PROTOCOL\fP (1).
-
-This option does not change the default proxy protocol (http).
-
-Without this option curl would make a guess based on the host, see \fI--url\fP
for
-details.
-
-Added in 7.45.0.
-.IP "--proto-redir <protocols>"
-Tells curl to limit what protocols it may use on redirect. Protocols denied by
-\fI--proto\fP are not overridden by this option. See --proto for how protocols
are
-represented.
-
-Example, allow only HTTP and HTTPS on redirect:
-
- curl --proto-redir -all,http,https http://example.com
-
-By default curl will allow all protocols on redirect except several disabled
-for security reasons: Since 7.19.4 FILE and SCP are disabled, and since 7.40.0
-SMB and SMBS are also disabled. Specifying \fIall\fP or \fI+all\fP enables all
-protocols on redirect, including those disabled for security.
-
-Added in 7.20.2.
-.IP "--proto <protocols>"
-Tells curl to limit what protocols it may use in the transfer. Protocols are
-evaluated left to right, are comma separated, and are each a protocol name or
-'all', optionally prefixed by zero or more modifiers. Available modifiers are:
-.RS
-.TP 3
-.B +
-Permit this protocol in addition to protocols already permitted (this is
-the default if no modifier is used).
-.TP
-.B -
-Deny this protocol, removing it from the list of protocols already permitted.
-.TP
-.B =
-Permit only this protocol (ignoring the list already permitted), though
-subject to later modification by subsequent entries in the comma separated
-list.
-.RE
-.IP
-For example:
-.RS
-.TP 15
-.B \fI--proto\fP -ftps
-uses the default protocols, but disables ftps
-.TP
-.B \fI--proto\fP -all,https,+http
-only enables http and https
-.TP
-.B \fI--proto\fP =http,https
-also only enables http and https
-.RE
-
-Unknown protocols produce a warning. This allows scripts to safely rely on
-being able to disable potentially dangerous protocols, without relying upon
-support for that protocol being built into curl to avoid an error.
-
-This option can be used multiple times, in which case the effect is the same
-as concatenating the protocols into one instance of the option.
-
-See also \fI--proto-redir\fP and \fI--proto-default\fP. Added in 7.20.2.
-.IP "--proxy-anyauth"
-Tells curl to pick a suitable authentication method when communicating with
-the given HTTP proxy. This might cause an extra request/response round-trip.
-
-See also \fI-x, --proxy\fP and \fI--proxy-basic\fP and \fI--proxy-digest\fP.
Added in 7.13.2.
-.IP "--proxy-basic"
-Tells curl to use HTTP Basic authentication when communicating with the given
-proxy. Use \fI--basic\fP for enabling HTTP Basic with a remote host. Basic is
the
-default authentication method curl uses with proxies.
-
-See also \fI-x, --proxy\fP and \fI--proxy-anyauth\fP and \fI--proxy-digest\fP.
-.IP "--proxy-cacert <file>"
-Same as \fI--cacert\fP but used in HTTPS proxy context.
-
-See also \fI--proxy-capath\fP and \fI--cacert\fP and \fI--capath\fP and \fI-x,
--proxy\fP. Added in 7.52.0.
-.IP "--proxy-capath <dir>"
-Same as \fI--capath\fP but used in HTTPS proxy context.
-
-See also \fI--proxy-cacert\fP and \fI-x, --proxy\fP and \fI--capath\fP. Added

-.IP "--proxy-cert-type <type>"
-Same as \fI--cert-type\fP but used in HTTPS proxy context.
-
-Added in 7.52.0.
-.IP "--proxy-cert <cert[:passwd]>"
-Same as \fI-E, --cert\fP but used in HTTPS proxy context.
-
-Added in 7.52.0.
-.IP "--proxy-ciphers <list>"
-Same as \fI--ciphers\fP but used in HTTPS proxy context.
-
-Added in 7.52.0.
-.IP "--proxy-crlfile <file>"
-Same as \fI--crlfile\fP but used in HTTPS proxy context.
-
-Added in 7.52.0.
-.IP "--proxy-digest"
-Tells curl to use HTTP Digest authentication when communicating with the given
-proxy. Use \fI--digest\fP for enabling HTTP Digest with a remote host.
-
-See also \fI-x, --proxy\fP and \fI--proxy-anyauth\fP and \fI--proxy-basic\fP.
-.IP "--proxy-header <header>"
-(HTTP) Extra header to include in the request when sending HTTP to a proxy.
You may
-specify any number of extra headers. This is the equivalent option to \fI-H,
--header\fP
-but is for proxy communication only like in CONNECT requests when you want a
-separate header sent to the proxy to what is sent to the actual remote host.
-
-curl will make sure that each header you add/replace is sent with the proper
-end-of-line marker, you should thus \fBnot\fP add that as a part of the header
-content: do not add newlines or carriage returns, they will only mess things
-up for you.
-
-Headers specified with this option will not be included in requests that curl
-knows will not be sent to a proxy.
-
-This option can be used multiple times to add/replace/remove multiple headers.
-
-Added in 7.37.0.
-.IP "--proxy-insecure"
-Same as \fI-k, --insecure\fP but used in HTTPS proxy context.
-
-Added in 7.52.0.
-.IP "--proxy-key-type <type>"
-Same as \fI--key-type\fP but used in HTTPS proxy context.
-
-Added in 7.52.0.
-.IP "--proxy-key <key>"
-Same as \fI--key\fP but used in HTTPS proxy context.
-.IP "--proxy-negotiate"
-Tells curl to use HTTP Negotiate (SPNEGO) authentication when communicating
-with the given proxy. Use \fI--negotiate\fP for enabling HTTP Negotiate
(SPNEGO)
-with a remote host.
-
-See also \fI--proxy-anyauth\fP and \fI--proxy-basic\fP. Added in 7.17.1.
-.IP "--proxy-ntlm"
-Tells curl to use HTTP NTLM authentication when communicating with the given
-proxy. Use \fI--ntlm\fP for enabling NTLM with a remote host.

-.IP "--proxy-pass <phrase>"
-Same as \fI--pass\fP but used in HTTPS proxy context.
-
-Added in 7.52.0.
-.IP "--proxy-service-name <name>"
-This option allows you to change the service name for proxy negotiation.
-
-Added in 7.43.0.
-.IP "--proxy-ssl-allow-beast"
-Same as \fI--ssl-allow-beast\fP but used in HTTPS proxy context.
-

-Same as \fI--tlsuser\fP but used in HTTPS proxy context.
-
-Added in 7.52.0.
-.IP "--proxy-tlsv1"
-Same as \fI-1, --tlsv1\fP but used in HTTPS proxy context.
-
-Added in 7.52.0.
-.IP "-U, --proxy-user <user:password>"
-Specify the user name and password to use for proxy authentication.
-
-If you use a Windows SSPI-enabled curl binary and do either Negotiate or NTLM
-authentication then you can tell curl to select the user name and password
-from your environment by specifying a single colon with this option: "-U :".
-
-If this option is used several times, the last one will be used.
-.IP "-x, --proxy [protocol://]host[:port]"
-Use the specified proxy.
-
-The proxy string can be specified with a protocol:// prefix to specify
-alternative proxy protocols. Use socks4://, socks4a://, socks5:// or
-socks5h:// to request the specific SOCKS version to be used. No protocol
-specified, http:// and all others will be treated as HTTP proxies. (The
-protocol support was added in curl 7.21.7)
-
-If the port number is not specified in the proxy string, it is assumed to be
-1080.
-
-This option overrides existing environment variables that set the proxy to
-use. If there's an environment variable setting a proxy, you can set proxy to
-\&"" to override it.
-
-All operations that are performed over an HTTP proxy will transparently be
-converted to HTTP. It means that certain protocol specific operations might
-not be available. This is not the case if you can tunnel through the proxy, as
-one with the \fI-p, --proxytunnel\fP option.
-
-User and password that might be provided in the proxy string are URL decoded
-by curl. This allows you to pass in special characters such as @ by using %40
-or pass in a colon with %3a.
-
-The proxy host can be specified the exact same way as the proxy environment
-variables, including the protocol prefix (http://) and the embedded user +
-password.
-
-If this option is used several times, the last one will be used.
-.IP "--proxy1.0 <host[:port]>"
-Use the specified HTTP 1.0 proxy. If the port number is not specified, it is
-assumed at port 1080.
-
-The only difference between this and the HTTP proxy option \fI-x, --proxy\fP,
is that
-attempts to use CONNECT through the proxy will specify an HTTP 1.0 protocol
-instead of the default HTTP 1.1.
-.IP "-p, --proxytunnel"
-When an HTTP proxy is used \fI-x, --proxy\fP, this option will cause non-HTTP
protocols
-to attempt to tunnel through the proxy instead of merely using it to do
-HTTP-like operations. The tunnel approach is made with the HTTP proxy CONNECT
-request and requires that the proxy allows direct connect to the remote port
-number curl wants to tunnel through to.
-
-See also \fI-x, --proxy\fP.
-.IP "--pubkey <key>"
-(SFTP SCP) Public key file name. Allows you to provide your public key in this
separate
-file.
-
-If this option is used several times, the last one will be used.
-
-(As of 7.39.0, curl attempts to automatically extract the public key from the
-private key file, so passing this option is generally not required. Note that
-this public key extraction requires libcurl to be linked against a copy of
-libssh2 1.2.8 or higher that is itself linked against OpenSSL.)
-.IP "-Q, --quote"
-(FTP SFTP)
-Send an arbitrary command to the remote FTP or SFTP server. Quote commands are
-sent BEFORE the transfer takes place (just after the initial PWD command in an
-FTP transfer, to be exact). To make commands take place after a successful
-transfer, prefix them with a dash '-'. To make commands be sent after curl
-has changed the working directory, just before the transfer command(s), prefix
-the command with a '+' (this is only supported for FTP). You may specify any
-number of commands.
-
-If the server returns failure for one of the commands, the entire operation
-will be aborted. You must send syntactically correct FTP commands as RFC 959
-defines to FTP servers, or one of the commands listed below to SFTP servers.
-
-This option can be used multiple times. When speaking to an FTP server, prefix
-the command with an asterisk (*) to make curl continue even if the command
-fails as by default curl will stop at first failure.
-
-SFTP is a binary protocol. Unlike for FTP, curl interprets SFTP quote commands
-itself before sending them to the server. File names may be quoted
-shell-style to embed spaces or special characters. Following is the list of
-all supported SFTP quote commands:
-.RS
-.IP "chgrp group file"
-The chgrp command sets the group ID of the file named by the file operand to
-the group ID specified by the group operand. The group operand is a decimal
-integer group ID.
-.IP "chmod mode file"
-The chmod command modifies the file mode bits of the specified file. The
-mode operand is an octal integer mode number.
-.IP "chown user file"
-The chown command sets the owner of the file named by the file operand to the
-user ID specified by the user operand. The user operand is a decimal
-integer user ID.
-.IP "ln source_file target_file"
-The ln and symlink commands create a symbolic link at the target_file location
-pointing to the source_file location.
-.IP "mkdir directory_name"
-The mkdir command creates the directory named by the directory_name operand.
-.IP "pwd"
-The pwd command returns the absolute pathname of the current working directory.
-.IP "rename source target"
-The rename command renames the file or directory named by the source
-operand to the destination path named by the target operand.
-.IP "rm file"
-The rm command removes the file specified by the file operand.
-.IP "rmdir directory"
-The rmdir command removes the directory entry specified by the directory
-operand, provided it is empty.
-.IP "symlink source_file target_file"
-See ln.
-.RE
-.IP "--random-file <file>"
-Specify the path name to file containing what will be considered as random
-data. The data may be used to seed the random engine for SSL connections. See
-also the \fI--egd-file\fP option.
-.IP "-r, --range <range>"
-(HTTP FTP SFTP FILE) Retrieve a byte range (i.e a partial document) from a
HTTP/1.1, FTP or SFTP
-server or a local FILE. Ranges can be specified in a number of ways.
-.RS
-.TP 10
-.B 0-499
-specifies the first 500 bytes
-.TP
-.B 500-999
-specifies the second 500 bytes
-.TP
-.B -500
-specifies the last 500 bytes
-.TP
-.B 9500-
-specifies the bytes from offset 9500 and forward
-.TP
-.B 0-0,-1
-specifies the first and last byte only(*)(HTTP)
-.TP
-.B 100-199,500-599
-specifies two separate 100-byte ranges(*) (HTTP)
-.RE
-.IP
-(*) = NOTE that this will cause the server to reply with a multipart
-response!
-
-Only digit characters (0-9) are valid in the 'start' and 'stop' fields of the
-\&'start-stop' range syntax. If a non-digit character is given in the range,
-the server's response will be unspecified, depending on the server's
-configuration.
-
-You should also be aware that many HTTP/1.1 servers do not have this feature
-enabled, so that when you attempt to get a range, you'll instead get the whole
-document.
-
-FTP and SFTP range downloads only support the simple 'start-stop' syntax
-(optionally with one of the numbers omitted). FTP use depends on the extended
-FTP command SIZE.
-
-If this option is used several times, the last one will be used.
-.IP "--raw"
-(HTTP) When used, it disables all internal HTTP decoding of content or transfer
-encodings and instead makes them passed on unaltered, raw.
-
-Added in 7.16.2.
-.IP "-e, --referer <URL>"
-(HTTP) Sends the "Referrer Page" information to the HTTP server. This can also
be set
-with the \fI-H, --header\fP flag of course. When used with \fI-L,
--location\fP you can append
-";auto" to the \fI-e, --referer\fP URL to make curl automatically set the
previous URL
-when it follows a Location: header. The \&";auto" string can be used alone,
-even if you don't set an initial \fI-e, --referer\fP.
-
-If this option is used several times, the last one will be used.
-
-See also \fI-A, --user-agent\fP and \fI-H, --header\fP.
-.IP "-J, --remote-header-name"
-(HTTP) This option tells the \fI-O, --remote-name\fP option to use the
server-specified
-Content-Disposition filename instead of extracting a filename from the URL.
-
-If the server specifies a file name and a file with that name already exists
-in the current working directory it will not be overwritten and an error will
-occur. If the server doesn't specify a file name then this option has no
-effect.
-
-There's no attempt to decode %-sequences (yet) in the provided file name, so
-this option may provide you with rather unexpected file names.
-
-\fBWARNING\fP: Exercise judicious use of this option, especially on Windows. A
-rogue server could send you the name of a DLL or other file that could possibly
-be loaded automatically by Windows or some third party software.
-.IP "--remote-name-all"
-This option changes the default action for all given URLs to be dealt with as
-if \fI-O, --remote-name\fP were used for each one. So if you want to disable
that for a
-specific URL after \fI--remote-name-all\fP has been used, you must use "-o -"
or
---no-remote-name.
-
-Added in 7.19.0.
-.IP "-O, --remote-name"
-Write output to a local file named like the remote file we get. (Only the file
-part of the remote file is used, the path is cut off.)
-
-The file will be saved in the current working directory. If you want the file
-saved in a different directory, make sure you change the current working
-directory before invoking curl with this option.
-
-The remote file name to use for saving is extracted from the given URL,
-nothing else, and if it already exists it will be overwritten. If you want the
-server to be able to choose the file name refer to \fI-J,
--remote-header-name\fP which
-can be used in addition to this option. If the server chooses a file name and
-that name already exists it will not be overwritten.
-
-There is no URL decoding done on the file name. If it has %20 or other URL
-encoded parts of the name, they will end up as-is as file name.
-
-You may use this option as many times as the number of URLs you have.
-.IP "-R, --remote-time"
-When used, this will make curl attempt to figure out the timestamp of the
-remote file, and if that is available make the local file get that same
-timestamp.
-.IP "-X, --request <command>"
-(HTTP) Specifies a custom request method to use when communicating with the
-HTTP server. The specified request method will be used instead of the method
-otherwise used (which defaults to GET). Read the HTTP 1.1 specification for
-details and explanations. Common additional HTTP requests include PUT and
-DELETE, but related technologies like WebDAV offers PROPFIND, COPY, MOVE and
-more.
-
-Normally you don't need this option. All sorts of GET, HEAD, POST and PUT
-requests are rather invoked by using dedicated command line options.
-
-This option only changes the actual word used in the HTTP request, it does not
-alter the way curl behaves. So for example if you want to make a proper HEAD
-request, using -X HEAD will not suffice. You need to use the \fI-I, --head\fP
option.
-
-The method string you set with \fI-X, --request\fP will be used for all
requests, which
-if you for example use \fI-L, --location\fP may cause unintended side-effects
when curl
-doesn't change request method according to the HTTP 30x response codes - and
-similar.
-
-(FTP)
-Specifies a custom FTP command to use instead of LIST when doing file lists
-with FTP.
-
-(POP3)
-Specifies a custom POP3 command to use instead of LIST or RETR. (Added in
-7.26.0)
-
-(IMAP)
-Specifies a custom IMAP command to use instead of LIST. (Added in 7.30.0)
-
-(SMTP)
-Specifies a custom SMTP command to use instead of HELP or VRFY. (Added in
7.34.0)
-
-If this option is used several times, the last one will be used.
-.IP "--resolve <host:port:address>"
-Provide a custom address for a specific host and port pair. Using this, you
-can make the curl requests(s) use a specified address and prevent the
-otherwise normally resolved address to be used. Consider it a sort of
-/etc/hosts alternative provided on the command line. The port number should be
-the number used for the specific protocol the host will be used for. It means
-you need several entries if you want to provide address for the same host but
-different ports.
-
-The provided address set by this option will be used even if \fI-4, --ipv4\fP
or \fI-6, --ipv6\fP
-is set to make curl use another IP version.
-
-This option can be used many times to add many host names to resolve.
-
-Added in 7.21.3.
-.IP "--retry-connrefused"
-In addition to the other conditions, consider ECONNREFUSED as a transient
-error too for \fI--retry\fP. This option is used together with --retry.
-
-Added in 7.52.0.
-.IP "--retry-delay <seconds>"
-Make curl sleep this amount of time before each retry when a transfer has
-failed with a transient error (it changes the default backoff time algorithm
-between retries). This option is only interesting if \fI--retry\fP is also
-used. Setting this delay to zero will make curl use the default backoff time.
-
-If this option is used several times, the last one will be used.
-
-Added in 7.12.3.
-.IP "--retry-max-time <seconds>"
-The retry timer is reset before the first transfer attempt. Retries will be
-done as usual (see \fI--retry\fP) as long as the timer hasn't reached this
given
-limit. Notice that if the timer hasn't reached the limit, the request will be
-made and while performing, it may take longer than this given time period. To
-limit a single request\'s maximum time, use \fI-m, --max-time\fP. Set this
option to
-zero to not timeout retries.
-
-If this option is used several times, the last one will be used.
-
-Added in 7.12.3.
-.IP "--retry <num>"
-If a transient error is returned when curl tries to perform a transfer, it
-will retry this number of times before giving up. Setting the number to 0
-makes curl do no retries (which is the default). Transient error means either:
-a timeout, an FTP 4xx response code or an HTTP 5xx response code.
-
-When curl is about to retry a transfer, it will first wait one second and then
-for all forthcoming retries it will double the waiting time until it reaches
-10 minutes which then will be the delay between the rest of the retries. By
-using \fI--retry-delay\fP you disable this exponential backoff algorithm. See
also
-\fI--retry-max-time\fP to limit the total time allowed for retries.
-
-If this option is used several times, the last one will be used.
-
-Added in 7.12.3.
-.IP "--sasl-ir"
-Enable initial response in SASL authentication.
-
-Added in 7.31.0.
-.IP "--service-name <name>"
-This option allows you to change the service name for SPNEGO.
-
-Examples: \fI--negotiate\fP \fI--service-name\fP sockd would use
sockd/server-name.
-
-Added in 7.43.0.
-.IP "-S, --show-error"
-When used with \fI-s, --silent\fP, it makes curl show an error message if it
fails.
-.IP "-s, --silent"
-Silent or quiet mode. Don't show progress meter or error messages. Makes Curl
-mute. It will still output the data you ask for, potentially even to the
-terminal/stdout unless you redirect it.
-
-Use \fI-S, --show-error\fP in addition to this option to disable progress
meter but
-still show error messages.
-
-See also \fI-v, --verbose\fP and \fI--stderr\fP.
-.IP "--socks4 <host[:port]>"
-Use the specified SOCKS4 proxy. If the port number is not specified, it is
-assumed at port 1080.
-
-This option overrides any previous use of \fI-x, --proxy\fP, as they are
mutually
-exclusive.
-
-Since 7.21.7, this option is superfluous since you can specify a socks4 proxy
-with \fI-x, --proxy\fP using a socks4:// protocol prefix.
-
-If this option is used several times, the last one will be used.
-
-Added in 7.15.2.
-.IP "--socks4a <host[:port]>"
-Use the specified SOCKS4a proxy. If the port number is not specified, it is
-assumed at port 1080.
-
-This option overrides any previous use of \fI-x, --proxy\fP, as they are
mutually
-exclusive.
-
-Since 7.21.7, this option is superfluous since you can specify a socks4a proxy
-with \fI-x, --proxy\fP using a socks4a:// protocol prefix.
-
-If this option is used several times, the last one will be used.
-
-Added in 7.18.0.
-.IP "--socks5-gssapi-nec"
-As part of the GSS-API negotiation a protection mode is negotiated. RFC 1961
-says in section 4.3/4.4 it should be protected, but the NEC reference
-implementation does not. The option \fI--socks5-gssapi-nec\fP allows the
-unprotected exchange of the protection mode negotiation.
-
-Added in 7.19.4.
-.IP "--socks5-gssapi-service <name>"
-The default service name for a socks server is rcmd/server-fqdn. This option
-allows you to change it.
-
-Examples: \fI--socks5\fP proxy-name \fI--socks5-gssapi-service\fP sockd would
use
-sockd/proxy-name \fI--socks5\fP proxy-name \fI--socks5-gssapi-service\fP
sockd/real-name
-would use sockd/real-name for cases where the proxy-name does not match the
-principal name.
-
-Added in 7.19.4.
-.IP "--socks5-hostname <host[:port]>"
-Use the specified SOCKS5 proxy (and let the proxy resolve the host name). If
-the port number is not specified, it is assumed at port 1080.
-
-This option overrides any previous use of \fI-x, --proxy\fP, as they are
mutually
-exclusive.
-
-Since 7.21.7, this option is superfluous since you can specify a socks5
-hostname proxy with \fI-x, --proxy\fP using a socks5h:// protocol prefix.
-
-If this option is used several times, the last one will be used.
-
-Added in 7.18.0.
-.IP "--socks5 <host[:port]>"
-Use the specified SOCKS5 proxy - but resolve the host name locally. If the
-port number is not specified, it is assumed at port 1080.
-
-This option overrides any previous use of \fI-x, --proxy\fP, as they are
mutually
-exclusive.
-
-Since 7.21.7, this option is superfluous since you can specify a socks5 proxy
-with \fI-x, --proxy\fP using a socks5:// protocol prefix.
-
-If this option is used several times, the last one will be used.
-
-This option (as well as \fI--socks4\fP) does not work with IPV6, FTPS or LDAP.
-
-Added in 7.18.0.
-.IP "-Y, --speed-limit <speed>"
-If a download is slower than this given speed (in bytes per second) for
-speed-time seconds it gets aborted. speed-time is set with \fI-y,
--speed-time\fP and is
-30 if not set.
-
-If this option is used several times, the last one will be used.
-.IP "-y, --speed-time <seconds>"
-If a download is slower than speed-limit bytes per second during a speed-time
-period, the download gets aborted. If speed-time is used, the default
-speed-limit will be 1 unless set with \fI-Y, --speed-limit\fP.
-
-This option controls transfers and thus will not affect slow connects etc. If
-this is a concern for you, try the \fI--connect-timeout\fP option.
-
-If this option is used several times, the last one will be used.
-.IP "--ssl-allow-beast"
-This option tells curl to not work around a security flaw in the SSL3 and
-TLS1.0 protocols known as BEAST. If this option isn't used, the SSL layer may
-use workarounds known to cause interoperability problems with some older SSL
-implementations. WARNING: this option loosens the SSL security, and by using
-this flag you ask for exactly that.
-
-Added in 7.25.0.
-.IP "--ssl-no-revoke"
-(WinSSL) This option tells curl to disable certificate revocation checks.
-WARNING: this option loosens the SSL security, and by using this flag you ask
-for exactly that.
-
-Added in 7.44.0.
-.IP "--ssl-reqd"
-(FTP IMAP POP3 SMTP) Require SSL/TLS for the connection. Terminates the
connection if the server
-doesn't support SSL/TLS.
-
-This option was formerly known as --ftp-ssl-reqd.
-
-Added in 7.20.0.
-.IP "--ssl"
-(FTP IMAP POP3 SMTP)
-Try to use SSL/TLS for the connection. Reverts to a non-secure connection if
-the server doesn't support SSL/TLS. See also \fI--ftp-ssl-control\fP and
\fI--ssl-reqd\fP
-for different levels of encryption required.
-
-This option was formerly known as --ftp-ssl (Added in 7.11.0). That option
-name can still be used but will be removed in a future version.
-
-Added in 7.20.0.
-.IP "-2, --sslv2"
-(SSL) Forces curl to use SSL version 2 when negotiating with a remote SSL
-server. Sometimes curl is built without SSLv2 support. SSLv2 is widely
-considered insecure (see RFC 6176).
-
-See also \fI--http1.1\fP and \fI--http2\fP. \fI-2, --sslv2\fP requires that
the underlying libcurl was built to support TLS. This option overrides \fI-3,
--sslv3\fP and \fI-1, --tlsv1\fP and \fI--tlsv1.1\fP and \fI--tlsv1.2\fP.
-.IP "-3, --sslv3"
-(SSL) Forces curl to use SSL version 3 when negotiating with a remote SSL
-server. Sometimes curl is built without SSLv3 support. SSLv3 is widely
-considered insecure (see RFC 7568).
-
-See also \fI--http1.1\fP and \fI--http2\fP. \fI-3, --sslv3\fP requires that
the underlying libcurl was built to support TLS. This option overrides \fI-2,
--sslv2\fP and \fI-1, --tlsv1\fP and \fI--tlsv1.1\fP and \fI--tlsv1.2\fP.
-.IP "--stderr"
-Redirect all writes to stderr to the specified file instead. If the file name
-is a plain '-', it is instead written to stdout.
-
-If this option is used several times, the last one will be used.
-
-See also \fI-v, --verbose\fP and \fI-s, --silent\fP.
-.IP "--tcp-fastopen"
-Enable use of TCP Fast Open (RFC7413).
-
-Added in 7.49.0.
-.IP "--tcp-nodelay"
-Turn on the TCP_NODELAY option. See the \fIcurl_easy_setopt(3)\fP man page for
-details about this option.
-
-Since 7.50.2, curl sets this option by default and you need to explictitly
-switch it off if you don't want it on.
-
-Added in 7.11.2.
-.IP "-t, --telnet-option <opt=val>"
-Pass options to the telnet protocol. Supported options are:
-
-TTYPE=<term> Sets the terminal type.
-
-XDISPLOC=<X display> Sets the X display location.
-
-NEW_ENV=<var,val> Sets an environment variable.
-.IP "--tftp-blksize <value>"
-(TFTP) Set TFTP BLKSIZE option (must be >512). This is the block size that
curl will
-try to use when transferring data to or from a TFTP server. By default 512
-bytes will be used.
-
-If this option is used several times, the last one will be used.
-
-Added in 7.20.0.
-.IP "--tftp-no-options"
-(TFTP) Tells curl not to send TFTP options requests.
-
-This option improves interop with some legacy servers that do not acknowledge
-or properly implement TFTP options. When this option is used
\fI--tftp-blksize\fP is
-ignored.
-
-Added in 7.48.0.
-.IP "-z, --time-cond <time>"
-(HTTP FTP) Request a file that has been modified later than the given time and
date, or
-one that has been modified before that time. The <date expression> can be all
-sorts of date strings or if it doesn't match any internal ones, it is taken as
-a filename and tries to get the modification date (mtime) from <file>
-instead. See the \fIcurl_getdate(3)\fP man pages for date expression details.
-
-Start the date expression with a dash (-) to make it request for a document
-that is older than the given date/time, default is a document that is newer
-than the specified date/time.
-
-If this option is used several times, the last one will be used.
-.IP "--tlsauthtype <type>"
-Set TLS authentication type. Currently, the only supported option is "SRP",
-for TLS-SRP (RFC 5054). If \fI--tlsuser\fP and \fI--tlspassword\fP are
specified but
-\fI--tlsauthtype\fP is not, then this option defaults to "SRP".
-
-Added in 7.21.4.
-.IP "--tlspassword"
-Set password for use with the TLS authentication method specified with
-\fI--tlsauthtype\fP. Requires that \fI--tlsuser\fP also be set.
-
-Added in 7.21.4.
-.IP "--tlsuser <name>"
-Set username for use with the TLS authentication method specified with
-\fI--tlsauthtype\fP. Requires that \fI--tlspassword\fP also is set.
-
-Added in 7.21.4.

-(TLS) Forces curl to use TLS version 1.2 when connecting to a remote TLS
server.
-
-Added in 7.34.0.
-.IP "--tlsv1.3"
-(TLS) Forces curl to use TLS version 1.3 when connecting to a remote TLS
server.
-
-Note that TLS 1.3 is only supported by a subset of TLS backends. At the time
-of writing this, those are BoringSSL and NSS only.
-
-Added in 7.52.0.
-.IP "-1, --tlsv1"
-(SSL) Tells curl to use TLS version 1.x when negotiating with a remote TLS
-server. That means TLS version 1.0, 1.1 or 1.2.
-
-See also \fI--http1.1\fP and \fI--http2\fP. \fI-1, --tlsv1\fP requires that
the underlying libcurl was built to support TLS. This option overrides
\fI--tlsv1.1\fP and \fI--tlsv1.2\fP and \fI--tlsv1.3\fP.
-.IP "--tr-encoding"
-(HTTP) Request a compressed Transfer-Encoding response using one of the
algorithms
-curl supports, and uncompress the data while receiving it.
-
-Added in 7.21.6.
-.IP "--trace-ascii <file>"
-Enables a full trace dump of all incoming and outgoing data, including
-descriptive information, to the given output file. Use "-" as filename to have
-the output sent to stdout.
-
-This is very similar to \fI--trace\fP, but leaves out the hex part and only
shows
-the ASCII part of the dump. It makes smaller output that might be easier to
-read for untrained humans.
-
-If this option is used several times, the last one will be used.
-
-This option overrides \fI--trace\fP and \fI-v, --verbose\fP.
-.IP "--trace-time"
-Prepends a time stamp to each trace or verbose line that curl displays.
-
-Added in 7.14.0.
-.IP "--trace <file>"
-Enables a full trace dump of all incoming and outgoing data, including
-descriptive information, to the given output file. Use "-" as filename to have
-the output sent to stdout. Use "%" as filename to have the output sent to
-stderr.
-
-If this option is used several times, the last one will be used.
-
-This option overrides \fI-v, --verbose\fP and \fI--trace-ascii\fP.
-.IP "--unix-socket <path>"
-(HTTP) Connect through this Unix domain socket, instead of using the network.
-
-Added in 7.40.0.
-.IP "-T, --upload-file <file>"
-This transfers the specified local file to the remote URL. If there is no file
-part in the specified URL, curl will append the local file name. NOTE that you
-must use a trailing / on the last directory to really prove to Curl that there
-is no file name or curl will think that your last directory name is the remote
-file name to use. That will most likely cause the upload operation to fail. If
-this is used on an HTTP(S) server, the PUT command will be used.
-
-Use the file name "-" (a single dash) to use stdin instead of a given file.
-Alternately, the file name "." (a single period) may be specified instead
-of "-" to use stdin in non-blocking mode to allow reading server output
-while stdin is being uploaded.
-
-You can specify one \fI-T, --upload-file\fP for each URL on the command line.
Each
-\fI-T, --upload-file\fP + URL pair specifies what to upload and to where. curl
also
-supports "globbing" of the \fI-T, --upload-file\fP argument, meaning that you
can upload
-multiple files to a single URL by using the same URL globbing style supported
-in the URL, like this:
-
- curl --upload-file "{file1,file2}" http://www.example.com
-
-or even
-
- curl -T "img[1-1000].png" ftp://ftp.example.com/upload/
-
-When uploading to an SMTP server: the uploaded data is assumed to be RFC 5322
-formatted. It has to feature the necessary set of headers and mail body
-formatted correctly by the user as curl will not transcode nor encode it
-further in any way.
-.IP "--url <url>"
-Specify a URL to fetch. This option is mostly handy when you want to specify
-URL(s) in a config file.
-
-If the given URL is missing a scheme name (such as "http://"; or "ftp://"; etc)
-then curl will make a guess based on the host. If the outermost sub-domain
-name matches DICT, FTP, IMAP, LDAP, POP3 or SMTP then that protocol will be
-used, otherwise HTTP will be used. Since 7.45.0 guessing can be disabled by
-setting a default protocol, see \fI--proto-default\fP for details.
-
-This option may be used any number of times. To control where this URL is
-written, use the \fI-o, --output\fP or the \fI-O, --remote-name\fP options.
-.IP "-B, --use-ascii"
-(FTP LDAP) Enable ASCII transfer. For FTP, this can also be enforced by using
an URL that
-ends with ";type=A". This option causes data sent to stdout to be in text mode
-for win32 systems.
-.IP "-A, --user-agent <name>"
-(HTTP)
-Specify the User-Agent string to send to the HTTP server. To encode blanks in
-the string, surround the string with single quote marks. This can also be set
-with the \fI-H, --header\fP option of course.
-
-If this option is used several times, the last one will be used.
-.IP "-u, --user <user:password>"
-Specify the user name and password to use for server authentication. Overrides
-\fI-n, --netrc\fP and \fI--netrc-optional\fP.
-
-If you simply specify the user name, curl will prompt for a password.
-
-The user name and passwords are split up on the first colon, which makes it
-impossible to use a colon in the user name with this option. The password can,
-still.
-
-When using Kerberos V5 with a Windows based server you should include the
-Windows domain name in the user name, in order for the server to successfully
-obtain a Kerberos Ticket. If you don't then the initial authentication
-handshake may fail.
-
-When using NTLM, the user name can be specified simply as the user name,
-without the domain, if there is a single domain and forest in your setup
-for example.
-
-To specify the domain name use either Down-Level Logon Name or UPN (User
-Principal Name) formats. For example, EXAMPLE\\user and address@hidden
-respectively.
-
-If you use a Windows SSPI-enabled curl binary and perform Kerberos V5,
-Negotiate, NTLM or Digest authentication then you can tell curl to select
-the user name and password from your environment by specifying a single colon
-with this option: "-u :".
-
-If this option is used several times, the last one will be used.
-.IP "-v, --verbose"
-Makes curl verbose during the operation. Useful for debugging and seeing
-what's going on "under the hood". A line starting with '>' means "header data"
-sent by curl, '<' means "header data" received by curl that is hidden in
-normal cases, and a line starting with '*' means additional info provided by
-curl.
-
-If you only want HTTP headers in the output, \fI-i, --include\fP might be the
option
-you're looking for.
-
-If you think this option still doesn't give you enough details, consider using
-\fI--trace\fP or \fI--trace-ascii\fP instead.
-
-Use \fI-s, --silent\fP to make curl really quiet.
-
-See also \fI-i, --include\fP. This option overrides \fI--trace\fP and
\fI--trace-ascii\fP.
-.IP "-V, --version"
-Displays information about curl and the libcurl version it uses.
-
-The first line includes the full version of curl, libcurl and other 3rd party
-libraries linked with the executable.
-
-The second line (starts with "Protocols:") shows all protocols that libcurl
-reports to support.
-
-The third line (starts with "Features:") shows specific features libcurl
-reports to offer. Available features include:
-.RS
-.IP "IPv6"
-You can use IPv6 with this.

-PSL is short for Public Suffix List and means that this curl has been built
-with knowledge about "public suffixes".
-.RE
-.IP "-w, --write-out <format>"
-Make curl display information on stdout after a completed transfer. The format
-is a string that may contain plain text mixed with any number of
-variables. The format can be specified as a literal "string", or you can have
-curl read the format from a file with "@filename" and to tell curl to read the
-format from stdin you write "@-".
-
-The variables present in the output format will be substituted by the value or
-text that curl thinks fit, as described below. All variables are specified as
-%{variable_name} and to output a normal % you just write them as %%. You can
-output a newline by using \\n, a carriage return with \\r and a tab space with
-\\t.
-
-.B NOTE:
-The %-symbol is a special symbol in the win32-environment, where all
-occurrences of % must be doubled when using this option.
-
-The variables available are:
-.RS
-.TP 15
-.B content_type
-The Content-Type of the requested document, if there was any.

-.RE
-.IP
-If this option is used several times, the last one will be used.
-.IP "--xattr"
-When saving output to a file, this option tells curl to store certain file
-metadata in extended file attributes. Currently, the URL is stored in the
-xdg.origin.url attribute and, for HTTP, the content type is stored in
-the mime_type attribute. If the file system does not support extended
-attributes, a warning is issued.
-.SH FILES
-.I ~/.curlrc
-.RS
-Default config file, see \fI-K, --config\fP for details.
-.SH ENVIRONMENT
-The environment variables can be specified in lower case or upper case. The
-lower case version has precedence. http_proxy is an exception as it is only
-available in lower case.
-
-Using an environment variable to set the proxy has the same effect as using
-the \fI-x, --proxy\fP option.
-
-.IP "http_proxy [protocol://]<host>[:port]"
-Sets the proxy server to use for HTTP.
-.IP "HTTPS_PROXY [protocol://]<host>[:port]"
-Sets the proxy server to use for HTTPS.
-.IP "[url-protocol]_PROXY [protocol://]<host>[:port]"
-Sets the proxy server to use for [url-protocol], where the protocol is a
-protocol that curl supports and as specified in a URL. FTP, FTPS, POP3, IMAP,
-SMTP, LDAP etc.
-.IP "ALL_PROXY [protocol://]<host>[:port]"
-Sets the proxy server to use if no protocol-specific proxy is set.
-.IP "NO_PROXY <comma-separated list of hosts>"
-list of host names that shouldn't go through any proxy. If set to a asterisk
-\&'*' only, it matches all hosts.
-
-Since 7.53.0, this environment variable disable the proxy even if specify
-\fI-x, --proxy\fP option. That is
-.B NO_PROXY=direct.example.com curl -x http://proxy.example.com
-.B http://direct.example.com
-accesses the target URL directly, and
-.B NO_PROXY=direct.example.com curl -x http://proxy.example.com
-.B http://somewhere.example.com
-accesses the target URL through proxy.
-
-.SH "PROXY PROTOCOL PREFIXES"
-Since curl version 7.21.7, the proxy string may be specified with a
-protocol:// prefix to specify alternative proxy protocols.
-
-If no protocol is specified in the proxy string or if the string doesn't match
-a supported one, the proxy will be treated as an HTTP proxy.
-
-The supported proxy protocol prefixes are as follows:
-.IP "socks4://"
-Makes it the equivalent of \fI--socks4\fP
-.IP "socks4a://"
-Makes it the equivalent of \fI--socks4a\fP
-.IP "socks5://"
-Makes it the equivalent of \fI--socks5\fP
-.IP "socks5h://"
-Makes it the equivalent of \fI--socks5-hostname\fP
-.SH EXIT CODES
-There are a bunch of different error codes and their corresponding error
-messages that may appear during bad conditions. At the time of this writing,
-the exit codes are:
-.IP 1
-Unsupported protocol. This build of curl has no support for this protocol.
-.IP 2
-Failed to initialize.
-.IP 3
-URL malformed. The syntax was not correct.
-.IP 4
-A feature or option that was needed to perform the desired request was not
