How to Install htop in Ubuntu, Debian, CentOS, Fedora
You can install htop from default repositories of most Linux distributions such as Ubuntu, Debian, CentOS, and Fedora simply through a Linux terminal and using Linux distribution specific package managers.
The htop is a powerful real-time system monitoring tool that offers a dynamic and interactive view of running processes and your server resource usage with detailed information for optimizing resource management.
Install htop on Linux using package managers (Quick way)
Installing htop, a user-friendly, powerful, customizable, and interactive process viewer tool, is an efficient way to manage and monitor your Linux VPS after buying.
Therefore any Linux system administrator needs htop to have essential insights into system performance and ensure optimal and smooth server operation.
Fortunately, most Linux distribution repositories include htop by default. You can install htop in Ubuntu, Debian, CentOS, and Fedora using common package managers. Access your Linux server, open the terminal (by pressing Ctrl+Alt+T ), and follow the below steps with Root or sudo access and a stable internet connection to install htop on Ubuntu, Debian, CentOS, Fedora:
1. Update your system package list:
Start the htop installation process in various Linux distributions by updating your system package list which is an essential step:
For Debian-based systems (Ubuntu, Debian, Linux Mint, etc) :
sudo apt updateFor CentOS/RHEL :
sudo yum updateFor Fedora:
sudo dnf updateFor Arch Linux and Manjaro :
sudo pacman -SyFor openSUSE:
sudo zypper refresh2. Install htop in different Linux Distros
Install htop in Debian-based systems (Ubuntu, Debian, Linux Mint, etc):
For Debian-based systems including Ubuntu and Debian, install htop tool using the apt package manager with the following commands:
sudo apt install htopInstall htop in CentOS/ RHEL:
For Red Hat-based systems including CentOS (on CentOS/RHEL 7), htop tool is available in the EPEL (Extra Packages for Enterprise Linux) repository, therefore first you must enable the EPEL repository using the following command:
sudo yum install epel-releaseThen you can install htop on CentOS/ RHEL systems using yum package manager:
sudo yum install htopInstall htop in Fedora:
For Fedora systems, install htop using dnf package manager by running the following command:

sudo pacman -Syu htopIn openSUSE:
sudo zypper refresh
sudo zypper update htopThe htop tool should be installed on your Linux system successfully to monitor your Linux system optimally.
Install htop on Linux Distributions from the source
If you require the latest version of htop to benefit from the latest features while it is not available in your distribution’s repositories, you can install htop from the source through the below steps:
1. Install necessary dependencies and build tools:
- For Debian/ Ubuntu:
sudo apt install build-essential libncursesw5-dev libncurses5-dev- For Red Hat/CentOS:
sudo yum groupinstall "Development Tools"sudo yum install ncurses-devel2. Download the latest release of htop from the official website or GitHub using wget command in Linux:
wget https://github.com/hishamhm/htop/archive/refs/tags/3.1.2.tar.gz3. Extract the tarball and navigate to the directory using the following command:
tar -xvf 3.1.2.tar.gz
cd htop-3.1.24. Compile and install the latest version of htop with:
./configure
make
sudo make installSo you have successfully installed the latest version of htop on your Linux system.
Install a specific version of htop on Linux
Through previous methods you have installed the latest version, however, you can install a specific or older version of htop on different Linux distributions based on your requirements. But how?
Here are steps to install specific versions of htop on Ubuntu, Debian, CentOS, Fedora, Manjaro, and openSUSE:
Using package manager
In Debian-based systems, first, you must find the PPA that supports your specific version of htop by looking for community repositories and add the appropriate PPA to your Debian-based system by running the following command:
sudo add-apt-repository ppa:example/ppa-nameThen install your desired htop version in Debian-based using:
sudo apt install htop=<version>For RPM-based systems including CentOS and Fedora, to install a specific version of htop, first check available versions in your package manager’s repositories with:
yum info htopNow, you can install your desired version of htop using the following command:
sudo yum install htop-<version>Installing htop from source code
If your desired version is not available in your package manager, alternatively you can install a specific version of htop from the source using the following command:
wget https://github.com/hishamhm/htop/archive/refs/tags/<version>.tar.gzReplace your desired version with <version> in the previous command.
Then, configure, compile, and install your desired version of htop by running the following command:
./configure
make
sudo make installYou are done and successfully have installed your specific version of htop. Using these methods depends on your specific requirements and the availability of the desired version in the archive.
However, using package managers for htop installation on a Linux server is the most straightforward method because installing htop from source requires more technical knowledge and might be more complex.
How to use htop on Linux VPS?
Now you have equipped your Linux system with a powerful process monitoring tool, it is time to benefit from htop features by starting the htop tool by running the below command and pressing Enter:
htopSample output:

# 1447 root 20 0 404M 101M 6068 S 0.0 5.0 0:00.73 /usr/sbin/NetworkManager --no-daemonAs you see htop shows the key information in two main sections. The top section returns a summary of overall system resources such as CPU, memory, swap usage, and load average (as a percentage and a bar graph). The bottom section lists total running processes with their PID, user, CPU usage, memory usage, virtual memory, resident memory, shared memory, status, and command.
As a result, htop provides you with overall real-time insights into your Linux system performance.
The htop provides an interactive interface, allowing easy navigation of the process list and killing or managing processes using function keys. To get a better understanding of htop function take a look at the htop keyboard shortcut keys and discover htop features:

Basic syntax of htop command
The main syntax of htop is as follows:
htop [options]htop command options
The htop does not have vast options, here are some common :
- –no-color, -C: Disables highlighting output with color./ Disables color-coded output.
- –tree,-t: Shows tree view of processes.
- –user =USERNAME,-u: Shows the processes owned by the specific user.

What is the Importance of htop for process management?
The htop is a valuable tool for Linux process management by offering a user-friendly interface and a real-time, interactive view of system processes.
Every running program or service on the system is a system process that has a unique process ID (PID). Optimally managing system processes is one of the important administration tasks that affect Linux system performance, stability, and security.
the user-friendly interface of htop provides you dynamic and understandable format to monitor and track CPU, memory, and swap usage, allowing you to identify resource-intensive processes or suspicious activity, kill problematic processes, analyze every process resource consumption, optimally allocate resources to different applications or services, and monitor system health and troubleshoot potential issues.
Using htop you can maintain a healthy and efficient Linux server by managing processes behavior and resource utilization.
