How to find the given program w/o knowledge about the package it belongs to?
I need to install the program iostat but i have no idea which package to choose.

[root@localhost ~]# yum provides iostat
Loaded plugins: langpacks, refresh-packagekit
sysstat-10.1.6-1.fc20.x86_64 : Collection of performance monitoring tools for Linux
Repo        : fedora
Matched from:
Filename    : /usr/bin/iostat

Et voila…
