Why not do away with the fragile binary characters here and instead do:
function settitle() { echo -ne "\e]2;[EMAIL PROTECTED];[EMAIL PROTECTED]"; }
Or the simpler:
function settitle() { echo -ne "\e]0;[EMAIL PROTECTED]"; }
I actually use the following, which sets the title via the prompt (which
means it's more persistent):
function settitle()
{
if [ $# -eq 0 ]
then
eval set -- "[EMAIL PROTECTED]: \\w"
fi
case $TERM in
xterm*) local title="\[\033]0;[EMAIL PROTECTED]";;
*) local title=''
esac
local prompt=$(echo "$PS1" | sed -e 's/\\\[\\033\]0;.*\\007\\\]//')
PS1="${title}${prompt}"
}
With this, it's nice to do:
$ PS1="\u\$ "
$ settitle "\\h: \\w"
This puts the user name in the prompt, and the host and working directory
in the title bar.
