|Barry, Ken,
|
|Thanks for your valuable scripting examples.  It sent me scurrying back to the
|man page to figure out case/esac and command substitution.  It's also a good
|reminder of the wealth of detail available in /proc.

For the record, this in .bashrc seems to work well in xterm's white background
and mintty's black background.

case "$(< /proc/$PPID/exename)" in
   */xterm) function setPS1() {
      PS1="\[\033]0;\w\007\033[32m\]\u@\h \[\033[35m\w\033[0m\]\n$" ;
      echo xterm
   } ;;
   */mintty) function setPS1() {
      PS1="\[\e]0;\w\a\]\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]\n\$" ;
      echo mintty
   } ;;
esac
