Another bash prompt trick
Authored by: dougc on Dec 22, '01 11:10:55AM

This is a cool tip, but I've never liked so much stuff in the prompt, so I split it up and put some into the title bar. My prompt is simply two lines:

export PS1='$USER@$HOST:{!}=>'

This line should be obvious. It will set your prompt to user@host and also display the command number. The command number is handy for executing a previous command. For example, !25 will execute command 25 in the history.

export PROMPT_COMMAND='echo -n "^[]1;$PWD^G"'

This line is a little tricky. What is not obvious are the characters in between the " ". The first character is a literal escape character. It is input in vi by typing ^V then pressing the escape key. These two keystrokes will produce the two characters ^[ . The next characters are just regular characters: ]1'$PWD . But the last character is a literal ^G. It is entered the same way as the escape, in vi type ^V then ^G. What all of this work will get you, is the current path (or whatever $PWD is set to) in the title bar of your terminal window.

This one rocks. Definitely better than what I posted.

Naw... It's nothing really. This is just old xterm stuff that I've never forgot.

BTW, thanks for pushing bash. I don't know how anyone can use csh based shells any more.

Setting the Terminal window title from tcsh

To set the title of the Terminal window from tcsh you do pretty much the same thing, except tcsh uses an alias to do its magic: alias cwdcmd 'echo -n "^[]1;$PWD^G"'

It's even easier than you guys are making it out to be. I set my bash prompt with the following:
PS1="\[\033]0;\u @ \h: \w\007\]\$ "
This sets my widow title to be "<username> @ <hostname>: <path> (ttyp?)".
