how to get source code of Unix commands?

Can anyone tell me how/where to get the source code for the unix commands like "ls ,finger,cp....etc" commands . I
have tried very hard but failed so far.

start at The GNU Operating system - the GNU project - Free Software Foundation - Free as in Freedom - GNU/Linux

I am not getting the source code on the given website...

Can you give more elaboration on it....

Thanks

All the major unix versions in the market are not free, that means you can't see the source code.
You may want to check out FreeBSD or OpenSolaris OR you may want to check out linux distros.
Almost all linux distros are free and you can check out the source code.

The link provided by porter is about GNU...It's all about open source movement.
I guess you didn't get the context of his message.

The complete directory of GNU utils. Check coreutils for source of ls, cp, etc.
