View Full Version : update window title

August 18th, 2009, 08:29 PM
I am trying to reproduce an issue with my taskbar flickering, but I need a simple script that will change a window title repeatability

I tried to do it by changing $PS1 a couple of times, but it only shows the last change.

PS1='\[\e]0;\u@\h:1 \w\a\]${debian_chroot:+($debian_chroot)}\u@\h:\w\$'
sleep 1

PS1='\[\e]0;\u@\h:2 \w\a\]${debian_chroot:+($debian_chroot)}\u@\h:\w\$'
sleep 1

PS1='\[\e]0;\u@\h:3 \w\a\]${debian_chroot:+($debian_chroot)}\u@\h:\w\$'
sleep 1

PS1='\[\e]0;\u@\h:4 \w\a\]${debian_chroot:+($debian_chroot)}\u@\h:\w\$'

tried executing it with
. scriptname

I don't have alot of gui experience so if someone knows of a quick way to do something like this it would be appreciated.

You can just echo an escape sequence to set a gnome-terminal title.
These title changes will go by too quickly to see them all.
You could add a sleep command if you want to slow them down.

title ()
echo -en "\033]2;$1\007"
for (( i=1; i<20000; i++ ))
title $i

That will work. Thank you

Where do I find documentation on the escape codes for future ref?

The gnome-terminal documentation is very weak at covering escape sequences.
The best approach is to look at the xterm escape sequences.
gnome-terminal attempts to match xterm (unless a feature has a security problem like getting a terminal to echo back arbitrary strings.)
Look here for a long list of xterm escape sequences-
