   I'd like to be able to specify a command to be run on every cd, pushd,
   popd.  (So I can put the current directory into the title of my xterm
   window.)


In my .bashrc:

xtitle () { echo -n -e "\033]l$*\033" }
function cd_xtitle () { 
   if [ "$cd_xtitle_pwd" != "$PWD" ]; then
      if [ -z "$tty" ]; then tty=`tty | sed -e s:/dev/ttyp::`; fi
      xtitle "$HOST:$PWD (${tty})"
      cd_xtitle_pwd=$PWD
   fi
}

case $TERM in
   xterm | hpterm)
     PROMPT_COMMAND=cd_xtitle
   ;;
esac
