Setting the cygwin title for telnet/ssh

Per default cygwin sets the PS1 variable so that the window title always shows the current directory. However, if you use telnet/ssh to login to a different computer, the title isn’t changed. If you tend to have several windows open (like myself), you end up with a lot of cygwin windows with unmeaningful names.

This morning I finally decided to do something about it, and wrote quick wrapper scripts for telnet. The script should be fairly self-explanatory:


#!/bin/sh

#
# Wrapper script to set window title to the host contacted.
#

# Helper function to set title of window
function settitle() { echo -ne “\e]2;$@\a\e]1;$@\a”; }

#
# Default cygwin PS1 also sets the title, effectively overriding any custom settings.
# We therefore set PS1 to zero, and restore it afterwards.
#
PS1_BCKUP=$PS1
PS1=
# Make sure PS1 is restored even in case of interrupts
trap “PS1=$PS1_BCKUP” 0
trap “exit 2″ 1 2 3 15

settitle $1
/usr/bin/telnet $1
