Source code for GNU utils?
 

hi, do you happen to know where can I find the source code for stuff like : the cp command? or any other commands such as mv or grep, etc?

I just want to see how these stuff were implemented, which is fascinating !

Thanks

Did you not think about going to the GNU website? cp, mv and friends are part of GNU Coreutils and grep, is well, GNU grep. Try googling to find a project's homepage and you'll be able to download the source from there.

Thanks, I've seen it only after I posted.


Thanks anyways./

On a debian-based distro, you can do it like this:

1. Make sure the source repositories are enabled in your /etc/apt/sources.list
2. Find out which package provides the program in question:
   
   Code:

   ---

   dpkg -S $(which mv)

   ---

3. Install source:
   
   Code:

   ---

   apt-get source packagename

   ---

I couldn't find the sources for other stuff I was looking like ps,
I'd be happy if you could guide me which package to look for the ps code, since I can't find it :(

procps. Looking at man pages usually helps, too ;).

Dude, just use your package manager (supposing you use one). It will be able to tell you what files belong to which package (matthewg42 gave some instructions for dpkg-based distros). Incidentally, on most linux distros, ps comes from the procps package.
