If you tell me which distro youre using I can give a far more precise
answer, but the vague version of the story is to use your distro's package
management system to find out which packages provide the programmes ls and
rm. Then download the source for those packages, and there you have it.

You could also have a hunt through the www.gnu.org website for "pure"

Just put the binary in a directory in your path. This could be somewhere
like /usr/bin .
To find out what directories are in your path run
echo $PATH
at the command prompt.
