A better way to manage this (more reliable and safer) is to use bash's
PROMPT_COMMAND variable (assuming that you use bash).  It also won't
be confused by things that change state (like your pwd) underneath you
without the use of cd (i.e. aliases, scripts, etc).

>From my .bashrc (sets the titlebar of an xterm or rxvt to
user@host:pwd, with "~" substitution if appropriate):

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

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

    my_dirname () { 
      if [ "${PWD#$HOME}" != "$PWD" ]
      then
    	  echo '~'${PWD#$HOME}
      else
    	  echo $PWD
      fi
    }
    export PS1='\n\!\$ '
	  PROMPT_COMMAND='eval set_titlebar `whoami`@`hostname`:`my_dirname`'
	  set +a
  else
    export PS1='\n\u@\h:\w\n\!\$ '
  fi 
fi
