Machine Type: i686-pc-linux-gnu
Bash Version: 4.1
Patch Level: 0
Release Status: release
Description:
Some of the time, using CRLF line endings cause syntax errors
in Bash scripts ("unexpected end of file").
This problem shows up on Bash 4.1 on Linux, Bash 3.2 on Linux,
and Bash 3.2 on Cygwin (where I first noticed it).
Repeat-By:
Create a file containing the following contents:
if true; then
echo foo;
fi
(This seems to be robust to a few changes: putting 'then' on
the next line; omitting the semicolon from the end of
'echo foo'.)
Verify that it works:
$ ./bash ../test.sh
foo
Convert the line endings to CRLF:
$ unix2dos ../test.sh
unix2dos: converting file ../test.sh to DOS format ...
Verify that it fails:
$ ./bash ../test.sh
../test.sh: line 4: syntax error: unexpected end of file
(Alternately, you can create it with CRLF, show that it
fails, dos2unix it, and show it now works.)
