How to change gnome-terminal title in Ubuntu 10

Question

I've tried setting my PROMPT_COMMAND variable:

PROMPT_COMMAND='echo -ne "\033]0;"myWindowTitle"\007"'

but something changes my tab (or the whole terminal title) to 'user@hostname:/current/path', thus

PROMPT_COMMAND='echo -ne "\033]0;"myWindowTitle"\007" && sleep 3'

changes title for 3 second only :)

Answer 1

PROMPT_COMMAND is issued before a prompt is set based on the PS1 variable. Probably you have some character sequence in PS1 which sets your windows title. You may invoke unset PS1 or set it to some other value:

export PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '

Alternatively you can set window title in your PS1 variable:

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

Answer 2

In Ubuntu the .bashrc file has some code that adds text to the PS1 variable. This extra text changes the title after you set it with the --title option. Just comment it.

# If this is an xterm set the title to user@host:dir
case "$TERM" in
xterm*|rxvt*)
    PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1"
    ;;
*)
    ;;
esac

Answer 3

Rather than do:

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

Try using a variable and setting this in your .bashrc:

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

Then you can simply do this to change the window title at the prompt by:

WT="my new window title"

If you like, you can include the path in the window title in your .bashrc:

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

BTW, I don't think you need to "export" PS1.
