I got this script originally from Jim Truher and have tweaked it a bit over time (nothing major). Basically it replaces your CD function with one that keeps a history.

  2. # Custom 'cd' command to maintain directory history
  3. #
  4. # Usage:
  5. #  cd          no args means cd $home
  6. #  cd <name>   changes to the directory specified by <name>
  7. #  cd -l       list your directory history
  8. #  cd -#       change to the history entry specified by #
  9. #
