htop is an interactive process viewer and manager for UNIX/Linux systems. It is a text-mode application and easy to use.

I usually use htop to show running process on my Linux servers even on my MacBook Pro.

Recently I turn my Linux server from Ubuntu distribution to CentOS distribution. And I found when I use yum install -y htop to install htop on CentOS, it failed.

After search on web, the commands below may be help.

yum install epel-release -y
yum install htop -y
