Trash Can

[Tim]

I'm trying to create a trash can that consist of Toss, Trashpick; and
Dispose. Toss is going to place files in a designated folder, Trashpick is
to recover files from the storage folder, and Dispose is to erase all files
in the storage folder. I'm not having much success with the little knowledge
I have with Unix. I would appreciate any good ideas or innovative ways to
accomplish this task.

[Nick Bachmann]

I made Bash scrips, delete, recycleutill, and deld, which do similar
things. This comes up about every 3 days on the list, so I will repost
them, with changes suggested by others on the list.

---

My notes on the scripts:

*DO NOT REPLACE rm WITH THESE. Call them delete or recycle. Other
scripts may call rm when they want something deleted forever. Also,
daemons/scripts may not put files in /home/user/.recycle, but in /.recycle.

*Delete now checks if .recycle and restored/ work.

*The scripts first tar and compress the file, then put it in ~/.recycle
with its name being utime-rand (utime is Unix time, rand is a random number)

*If your tar doesn't support z, get one that does, or run gzip.

*Run deld as a cron job, it deletes files that are 21, 22, or 23 days old.

*I put deld in /usr/local so it wouldn't be in PATH, so I could use Tab
to autocomplete delete after typing 'del'

*[hermie@gandalf hermie]$ ls -al /bin/sh
lrwxrwxrwx 1 root root 4 Jun 10 08:37 /bin/sh -> bash

*Recycleutill is a front end for undeleting. It needs some work. Users
enter which file they want examined, it it tells them its contents.

*Enjoy! Let me know how useful they are, and if I forgot to include
anything.
