Well I don't know any such tool, but I would be willing to extend the rm
of DOG to accept @listfile. (I've been looking for some inspiration on to
code on DOS, and I feel this is it. Thanx :)

I guess I could do this too.

A nice and compace spec ;)

C rules ;)... Hmmm I'll see what I'll cook up.

OK I'll start with that.

you do know that rm can do -r to remove recursively combine it with with
-f and rm will also whisk away the dirs. so you would say:

and get no complaints, and no stale dirs either. Linux is nice ;)

Phew ;) (post bash to DOS...)

yes there is. (IIRC)
and same goes for rm and ls BTW (which I like using)

Yeah. I agree. Guess what? When I complete this we will have a rudimentary
package handler... Hmmm I think I'll have another clooose look at the .dep
package system (it has some nice features like installation scripts inside
the .deb itself, dependencies etc... ;)

Back to earth...
Here is my plan:

1. change rm (of DOG) so that it accepts @filename as a file with a list
of files to remove (should be easy)
2. I'll write some install / uninstall batch progs
3. examine .deb with a microscope (i.e. read docs and code...)
4. think... :)

What do you think?
