Well, I am back again and you may not be rejoicing.
This is CAN 2.0.
Yes it is all (almost all) new.
First, what you need to do to make this nifty thing for yourself
or your system (if you are the system manager)
1. Copy the appropriate Makefile to Makefile and then compile.
2. Edit emptytrash to make it look in the trashcans of your system.
3. Install all of this wonderful stuff (Don't forget the man pages).
Make sure to make "emptytrash" executable by the crontab that will run it.
Second, So why have you wasted my time again or why version 2.0?
1. Well, I rewrote the entire can in C. This made it move twice as fast.
Still a little slower than rm but certainly much nicer.
2. In the process of rewriting it, I added the verbose option and the
interactive option.
Third, There are some things about this that you should know.
1. This is my first attempt at a "C" utility but as far as I can tell,
it does the trick.
2. It only changes the access time, not the modification time and then
empties trash on the basis of access time. So, if you are really
hard-core, you can see if the one you removed and then recovered is
really the version you want.
3. This has the same handicap as my original script. You can only recover
one file at a time, and you must know it's specific name. If I have
time I will try my best to fix this problem.
4. The listing option is very primitive but since it traverses the
directory tree by where it is placed, the last things canned are
usually at the end of the list. I, once again, will do what I can
to repair these features (bugs?).
5. This is my first time passing around multiple system designs.
If I have a poor conception of what any system is like please let
me know at the address below. (rhyme?)
6. You may have the possibility of a pathname greater than 80. I rarely do.
To remedy any problems caused by this, simply change the define
entitled MAXPATHLEN.
7. May be possible to add a force option, but I don't see the necessity
of it right now.
If you have any complaints or you have bug fixes or
anything of the sort please write me at
"athey@nosc.mil"
Please write me if you install this and find it useful.
Just a quick note would be great, everybody.
I mean let me know if I should keep posting this artwork (junk?).

NOTE: CAN 2.01 now we can deal with cross device canning.
NOTE: CAN 2.02 segmented and cleaned code.
