Is there any way to have command options included for certain commands?
i.e. to have some sort of script or regex look allow me to have
ssh:address@hidden, or irc:irc.freenode.net
screen does not support this; its automatic titling stuff is relatively
simple. Since you're running tcsh, you could use the postcmd alias to
achieve what you want. (postcmd is tcsh's analog to zsh's preexec.)
Don't you mean precmd?
I see form my notes that the tcsh invocation to get the name of the
current command into the shelltitle is
Here's what I've got:
set prompt="%{\ek\e\\%}\%"
Note that the shell builtin "echo" and the set command both understand \e
as echo, so we don't.
alias postcmd 'echo -ne "^[k\!#:0^[\\"'
(man echo reveals that FreeBSD's echo doesn't support -e -- also, echo is
probably being interpreted by tcsh's echo builtin)
so this should do roughly what you want:
alias postcmd 'echo -ne "^[k\!#:0 \!#:$^[\\"'
Nope, gives me this:
\ekendif endif\e\\% for my first prompt (all other prompts are normal.)
What should I have my shelltitle set to?

Now, for zsh, I might do something like this:
preexec () {
if [[ "$TERM" == "screen" ]]; then
local CMD="${1[(wr)^(<*|*=*|sudo|exec|-*)]}
${1[(wrn:2:)^(<*|*=*|sudo|exec|-*)]}"
echo -n "\ek$CMD\e\\"
fi
}
which pulls out the first and second non-variable, non-input redirection,
non-option elements of the command line. (It's not terribly happy if
there isn't a second (or first, for that matter) such element.)
