#1

Hello all.
I’m a newbie in Linux.
I have openSUSE 11.1.

I need sources of ‘top’ and ‘df’ utilites.
Could you say me where I can find they.

Thank you.

$ rpm -qf which top df
procps-3.2.7-147.22
coreutils-6.12-32.10

So top comes from the procps package and df comes from the coreutils package.
