Here's another option (from my .bashrc) that works with rxvt's (and
xterms?).  It dynamically sets the title bar to user@machine:pwd so
you don't have to have it all on the prompt.  If you're not using an
xterm/rxvt, it sets the prompt instead.  It also does /home/username
-> ~ translation when appropriate.

if [ ${PS1:-UNSET} = UNSET ]
then
	INTERACTIVE_SHELL=F
else
	INTERACTIVE_SHELL=T

  if [ "$TERM" = x"term" ]
  then
    set_titlebar () { echo -n "]2;$*"; }
    export -f set_titlebar

    my_dirname () { 
      if [ "${PWD#$HOME}" != "$PWD" ]
      then
    	  echo '~'${PWD#$HOME}
      else
    	  echo $PWD
      fi
    }
    export -f my_dirname

    export PS1='\n\!\$ '
	  export PROMPT_COMMAND='eval set_titlebar `whoami`@`hostname`:`my_dirname`'
  else
    export PS1='\n\u@\h:\w\n\!\$ '
  fi 
fi
