Homework & Coursework Questions

I just need to edit the "rm" command such that it should move all the files / directories to particular folder instead of deleting.

Its regarding my dessertation work , started working on the source code coreutils/src/rm , can any one guide mw to create a new source code for "rm " such that it should move all the files / dir to a particulat folder instead of deleting.

Try just aliasing rm to something else in your shell's login. This will make all rm's called interactively in your account run whatever program you want.

If you really must intercept all calls to rm, there's problems.
1) Your backup dir will pile high with useless temporary files.
2) Modifying the source code of rm may not be particularly helpful. It's not a good starting point for one thing -- it does nothing remotely like what you want. It'd make more sense to replace rm with a shell script, so the admin (or yourself, a year later) can discover and realize just what exactly you were up to.
3) Binary programs don't need to run rm to delete a file, they can just use the unlink() system call.
