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.
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:
The first thing to do, is to verify if your repositories are up-to-date
The next step is to install "htop":
apt-get install -y htop
The "-y" argument above, automatically accepts the package installation!
For these distributions, you will notice that htop package is generally missing from official repositories. It is therefore necessary to use the "EPEL" repositories:
yum install htop
Installing EPEL repositories:
yum install epel-release
If the "epel-release" package does not exist, you will need to install it manually:
rpm -ivh https://mir01.syntis.net/epel/7/$(arch)/e/epel-release-7-5.noarch.rpm
rpm -ivh http://fr2.rpmfind.net/linux/epel/6/$(arch)/epel-release-6-8.noarch.rpm
RHEL / CentOS 5.x
rpm -ivh http://mirror.in2p3.fr/pub/epel/5/$(arch)/epel-release-5-4.noarch.rpm
Install the htop package:
yum install htop
Simply use emerge to install the package.
A manual installation from sources may be required when:
Installation and compilation of htop should work on most systems provided you have the right tools!
We'll start by downloading the sources:
Then we will extract this archive:
tar zxf htop-1.0.3.tar.gz
And now we will compile our tool:
./configure; make; make install
Normally, if your installation was successful and has returned an error message, you run htop with the following command:
