rm is part of coreutils, so you are lookin in the correct place. You answered your own question so...

I'm a C++ developer and i use like this:

Code:

// Remove.cpp
#include <iostream>

int main() {
    remove("test.txt");
  return 0;
}

But this is a very simple code, we can add if structures and some other things!
But, you have experience in which languages?

Hi all thanks , but i need to study the code for commands rm & mv , so that i can try to develop a new command "delete" ,as while deleting a file a zipped copy of the file is moving to a marked location.

Can any one get me the actual code for the commands...

You are really going to have a hard time to do this if you can't even figure that out...

Code:

$ tar xf /var/portage/distfiles/coreutils-7.5.tar.gz 
$ cd coreutils-7.5/
$ ls src/rm*
src/rm.c  src/rmdir.c
$ ls src/mv*
src/mv.c

The names of the files are evident enough. If you truly have looked into the source of coreutils (I think you didn't) it's very hard to miss these, the names of the files are self-explanatory.

Thanks , From coreutil/src/rm & coreutils/src/mv i have started learning the codes for rm & mv .

hope after studying i can edit the code in such a way once giving the rm command the marking file will dump to a destination folder.

Please let us know apart from this coreutil/src/rm & coreutils/src/mv what are all the supporting files that i should check and edit while applying this to kernel.

If any one aware of these script ,please let us know how to edit this rm script what are the supporting scripts for this.....
