Re: Prompt in Bash

[Rob Browning <rlb@cs.utexas.edu>]

Ask and ye shall receive :> This is a cut-down version of my bashrc.
It also shows a trick to get around the problem with some shells
actually being login shells, but not calling .bash_login (i.e. X login
shells).  I just symlink my .bash_login to my .bashrc, and let .bashrc
handle figuring out what kind of shell it is (see BASH_INITIALIZED
below).

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

  if [ "$TERM" = xterm -o "$TERM" = rxvt ]
  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

if [ "${BASH_INITIALIZED}" != "Yes" ]
then
	export BASH_INITIALIZED=Yes

  # Do other stuff here that should only happen once, and be
  # inherited by sub-shells.

fi
