I’m still learning my way through Red Hat Enterprise Linux, and today went looking for htop. Unfortunately, its not quite as easy as installing through yum from the default repositories, so we must dig a bit deeper. By adding the Extra Packages for Enterprise Linux (EPEL), provided by the Fedora Project, to the repository list, we can then install htop, as well as a number of other great packages.

# as root
rpm -Uvh http://download.fedora.redhat.com/pub/epel/6/x86_64/epel-release-6-5.noarch.rpm
yum install htop

Bang. Easy.
