While the top utility gives us a basic overview of the processes running on your Linux system, the htop utility goes further, by giving us additional information about the processes and also allow several manipulations.
To install htop, sort the list of processes using criteria such as: CPU usage, memory, virtual memory, and others and then, search for a process. Next, kill the process.
Automatic installation from repositories (Most distributions )
The htop package exist for most of the Linux distributions, thus allowing easy installation via the package manager!
This is the generic procedure to be used:
NB: all commands are entered as root (admin), alternatively you can use the sudo program to execute a command as root (Ubuntu/Kubuntu/Lubuntu/Xubuntu).
Installation in Debian, Ubuntu, Linux Mint and derivatives (Kubuntu, Lubuntu, Xubuntu, LMDE, etc)
The first thing to do, is to verify if your repositories are up-to-date
apt-get update
The next step is to install "htop":
apt-get install -y htop
The "-y" argument above, automatically accepts the package installation!
Fedora, CentOS, RedHat and others
For these distributions, you will notice that htop package is generally missing from official repositories. It is therefore necessary to use the "EPEL" repositories:
Fedora
yum install htop
CentOS, RHEL, Scientific Linux and other
Installing EPEL repositories:
yum install epel-release
If the "epel-release" package does not exist, you will need to install it manually:
RHEL/CentOS 7.X
