[buug] How to show directory at prompt?

[Gary Yang]

Hi,
   
  My path includes several directories. See below as an example.
   
  hostname:gary_scripts>pwd
  /work/gary/gary_scripts/cm/MAIN
   
  I only want to show the directory, gary_scripts (the third directory in the path) at the prompt. The directory gary_scripts shows at the prompt when I am in this directory or its sub-directories. It is not showed at prompt if I am not under this directory. I can easily make it in Korn Shell using the lines below. I put these two lines in a file and source it. But, I am no good at C-Shell. Anyone has idea of how to do it in C-Shell?
   
  my_cd() { \cd "$1"; PS1="`hostname`:`pwd | awk -F/ '{print $4}'`>"; }
  alias cd=my_cd
   
   
  Thanks,
   
   
  Gary
