How to add a title to xterm

[Robert Body]

Here is a script that works in bash or ksh for setting the title based on 
your current path, by setting up $PS1. I have also seen similar thing done 
by aliasing "cd" command

I use bash mostly, but for ksh there is need for Perl in my script below to 
accomplish the passing of ESC characters to ksh. I could not figure out how 
to do it with awk

case "`echo "_$0" | /usr/bin/tr '[:upper:]' '[:lower:]' | sed -e 's/^_//'`"

><your title> ^G . You can do it from the xterm application (writing to
>/dev/tty or stdout if its connected, or externally, by writing to
>/dev/tty<n> [Cygwin] or /dev/pts/<n> [Linux]).
