Here's a small patch for xterm.
Using tcsh, I set re-set the title of xterm before each shell prompt,
so that it states my current working directory. This ensures that my
title is up to date, no matter where I am, or what I'm doing.
But what would really bug me is that the most of the time, the
update would not be necessary, and would cause an unsightly flicker
of the title bar.
I hacked xterm where it set the title, so that it would only
set the new title if it had actually changed.
It should also work for the icon name, but I never change that,
so I don't know if it does.
There may be a more correct way of doing this, but it works for me.
Standard disclaimers apply.
Duncan Sinclair.
----------------
To apply, cd into the xterm source directory (<mumble>/mit/clients/xterm),
and run `patch <this-file'.
You can build xterm seperate from the rest of the X source using xmkmf.

Which doesn't work if you have, say, a super user shell that you keep suspended in the background for easy access to super user powers. If you only update the title with the current working directory when you do a ``cd'' then a suspend of the super user shell or a foregrounding of it won't set the prompt. I also used to include an update of the current working directory in my prompt string and was annoyed by the flicker. Nice patch if it works. I'll have to give it a shot. You should submit it to the regular xbugs address for inclusion in R5. Casey

(This should work for any shell with something equivalent >to an aliasing mechanism). Show me a way to make it work in this scenario: Say I have two suns called `midway' and `vanuata'. I am running an xterm on midway, and so have, say, the title bar: "midway:/usr/X11/src/local/tvtwm" In /usr/hosts there are links from midway & vanuata to /usr/ucb/rsh. This allows me to type `vanuata' to rlogin onto it. Once I reach vanuata, the title bar becomes: "vanuata:/users/grad/sinclair" I run a few commands, then logoff, returning to midway. In my system I now have the correct title bar, in other systems I don't. I did use the alias method before, but I'm too much of a perfectionist, and I just wasn't happy with it. I could create my own equivalent `/usr/hosts', with a ton of shell scripts so that the title would be reset automatically, but that would be too much hassle for such a little thing. Instead I use tcsh's "precmd" alias, and put a small hack into xterm which can be useful either way.

Well, I have an answer for this one if you use a modern Bourne shell (one with shell functions): # Define functions for labeling window title and icon, where available. case "$TERM" in xterm) case "$BANNER" in console) # BANNER=console xterm -T console -C -ls title_bar() { echo "\033]0;console:$TCWD\007\c"; } icon_name() { echo "\033]1;console\007\c"; } PS1="console$ ";; *) # X window title_bar() { echo "\033]0;$HOST:$TCWD\007\c"; } icon_name() { echo "\033]1;$HOST\007\c"; };; esac;; sun*) case "BANNER" in console) # BANNER=console cmdtool -C title_bar() { echo "\033]lconsole:$TCWD\033\\\\\c"; } icon_name() { echo "\033]Lconsole\033\\\\\c"; } PS1="console$ ";; *) #Suntools window title_bar() { echo "\033]l$HOST:$TCWD\033\\\\\c"; } icon_name() { echo "\033]L$HOST\033\\\\\c"; };; esac;; iris*) case "`tty`" in /dev/console) #Iris console window title_bar() { echo -n "\033P1.yconsole:$TCWD\033\\"; } PS1="console$ ";; *) #Iris window title_bar() { echo -n "\033P1.y$HOST:$TCWD\033\\"; };; esac;; tty5620*) # 5620 myx software title_bar() { myxban -l "$HOST:$TCWD"; myxban -r "$SHELL"; };; tty630*) # 630 layers software title_bar() { echo '\033[?'`expr "$PS1" : '.*'`";2v$PS1\c"; };; *) # other terminals title_bar() { PS1="$HOST:$TCWD$ "; };; esac cd() { PREVDIR="$CWD" # used by backd() case $# in 0) builtin cd;; *) builtin cd "$1";; esac CWD=`pwd` case $CWD in $HOME*) TCWD=`echo $CWD | sed -e "s!^$HOME!~!" `;; *) TCWD=$CWD;; esac title_bar icon_name }

This may be a nit, but what is wrong with cwdcmd in tcsh? It does
what you want with a minimum of fuss and without messing with the
xterm source. When I ran tcsh I used the following for my xterms and
never got that annoying flicker. (Note that the ^[ are real escapes,
and the ^G and ^A are real control characters.)

No need to do that, just make the aliasing conditional. Here's what I have in my .bashrc. if [ "(" "$TERM" = "xterm" ")" -o "(" "$TERM" = "xterm+" ")" ] ; then set_headline() { case "$PWD" in ${HOME}*) echo -n "\033]0;`expr $PWD : $HOME'\(.*\)'`\007" ;; *) echo -n "\033]0;${PWD}\007" ;; esac } cd() { builtin cd $*; set_headline; } pushd() { builtin pushd $*; set_headline; } popd() { builtin popd $*; set_headline; } pwd() { builtin pwd ; set_headline ; } set_headline fi Michael -- Michael Elbel | Wollen haetten wir schon moegen me@dude.PCS.COM | aber duerfen haben wir uns nicht getraut. | - Karl Valentin

I called it 'cd' | originally, but I noticed that when I ran sunview (to use some non-X stuff) | the escape sequences seem to cause the SunView 'shelltool's to hang. This occurs because xterm and shelltool use different escape sequences to set the title string. Xterm uses ^[]2;yourtexthere^G whereas SunView shelltool uses ^[]lyourtexthere^[\ By coincidence, X11R3 and earlier versions of xterm would accept a string similar to SunView's. You could set an xterm with the same sequence, except that the string would be terminated by ESC instead of ESC-backslash. So, if you programmed your shell to emit ^[]lyourtexthere^[ to set the title string for xterm, and then moved over a SunView shelltool, the shelltool would "hang" building up the title string. It would stay "hung" until it got ESC-backslash. This happened to me once. The resulting title string was quite amusing once I got the shelltool out of that mode. Now my shells base their title-setting sequences on the terminal type. s'marks Stuart W. Marks ARPA: smarks@eng.sun.com Windows & Graphics Software UUCP: sun!smarks Sun Microsystems, Inc.
