Safe RM

Safe-Remove/Restore Project

• Create a recycle bin at $HOME/deleted (default).
• Recycle bin location can be customized by using $HOME/.rm.cfg or env variable $RMCFG.
• To avoid name conflicts in the recycle bin, the file name is changed to the original name followed by an underscore and then followed by the inode. * For example, if a file named "f1" with inode 1234 were removed, the file would be named f1_1234 in the recycle bin.
• Original directory and filename are stored in $HOME/.restore.info * Each line of this file contain the name of a stored file, followed by a colon, followed by the original full path and filename. * For example, if file f1 with inode 1234 were removed from the /home/usr1.name/ directory and another file named f1 with inode 5432 were removed from the /home/usr1.name/testing directory then .restore.info would contain:
  • f1_1234:/home/usr1.name/f1
  • f1_5432:/home/usr1.name/testing/f1
• To restore a file use safe_rm_restore * For example: safe_rm_restore f1_1234
• Error checking
  • Use "safe_rm" without a name of a file - error message
  • Use "safe_rm file1" and file1 does not exist - error message
  • Use "safe_rm dir1" and dir1 is a directory - error message
  • Try to restore a file that does not exist in the recycle bin - error message
  • If the restoring file already exists in the target directory, it will prompt "Do you want to overwrite?"
• safe_rm supports wildcards and option flags: -i for interactive, and -v for verbose, -r or -R to remove file(s) and directories recursively. * Example:
  • safe_rm file1 file2 file3
  • safe_rm *
  • safe_rm -ivr *
