If you have bash, then this is a cleaner way:

host=$(uname -n)
if [ "${TERM}" = "xterm" -o "${TERM}" = "xterm-color" ]
then
   if [ -z "${BASH}" ]
   then
      echo "\033]2;${host}\007\033]1;${host}\007"
   else
      export PROMPT_COMMAND=\
      'echo -ne "\033]2;${host}:${PWD}\007\033]1;@${host}:${PWD}\007"'
   fi
fi

Also, for VIM just add "set title" to your .vimrc.  Bash with the
PROMPT_COMMAND set as above will set it back when you exit.
