  3. #  This script is to be called by an alias of the rm command
  4. #  e.g. using the entry...
  5. #  alias rm='sh /home/user1/my_scripts/rm_replacement.sh'
  6. #  in your $HOME/.profile or $HOME/.bashrc file
  7. #
  8. #  It will move rm files to /home/user1/.RecycleBin
  9. #  You need to create the directory /home/user1/.RecycleBin if
  10. #  it doesn't already exist
  11. #
  12. #  If a file/directory with the same name already exists in the
  13. #  RecycleBin, the file/directory already in the RecycleBin
  14. #  will be renamed taging "_X" on to the end where
  15. #  X is an incremental number and then the newly rm'd
  16. #  file/directory will be copied into the RecycleBin
  17. #
  18. #  Consequently the latest version of the file will be its normall
  19. #  name, without any extension.
