Setting the PuTTY window title from command line

I sometimes want to set the title of my PuTTY windows, like "Editor", "Compiler", etc. to identify distinct windows. I found the following script very useful. You can add that to your ~/.bash_profile. Once you login, you can set the title to whatever you want:

function wtitle {
if [ "$TERM" == "xterm" ] ; then
# Remove the old title string in the PS1, if one is already set.
PS1=`echo $PS1 | sed -r 's/^\\\\\[.+\\\\\]//g'`
export PS1="\[\033]0;$1 - \u@\h:\w\007\]$PS1"
else
echo "You are not working in xterm. I cannot set the title."
fi
}

The above function will make the window title to be whatever argument you give followed by the usual user@host:workingdirectory. I think this should work with any xterm client. Not just PuTTY. (I haven't tested with any other xterm client.)

For e.g. to set the window title to be Editor, you would give the following command:

wtitle Editor
