Don't use cd aliases for showing the current path in your xterm
titlebar.  There's a more elegant way involving PROMPT_COMMAND:

     bash-2.05b$ export PS1='\$ '
     $ export PROMPT_COMMAND='echo ::`pwd`::'
     ::/home/keramida::
     $ cd /etc
     ::/etc::
     $ cd /usr/src
     ::/usr/src::
     $ exit
     exit

You can set PROMPT_COMMAND to any command you want, no matter how
complicated.  A nice wrapper script around your "usual stuff" for
PROMPT_COMMAND can be called too with:

     $ export PROMPT_COMMAND='/home/keramida/bin/promptcmd.sh'

Regarding the current username, host name and directory, you might be
interested in this output too:

     $ echo $USER
     keramida
     $ hostname -s
     orion
     $ echo $PWD
     /home/keramida
     $
