how to install htop on rhel 9

First, make sure your system is up to date:

sudo dnf update -y

Now check if the EPEL (Extra Packages for Enterprise Linux) repository is available. While htop used to require EPEL in older versions, RHEL 9 often includes it in AppStream or BaseOS repositories.

Try installing htop directly:

sudo dnf install htop -y

If that works, you’re done. Run it with:

htop

If htop is not found in your default repositories, enable the EPEL repository:

sudo dnf install epel-release -y

Then refresh your repo list:

sudo dnf update -y

Try installing htop again:

sudo dnf install htop -y

After installation, launch htop:

htop

If you want htop to open every time you SSH into the server, you can add it to your .bash_profile:

echo "htop" >> ~/.bash_profile

To remove htop later:

sudo dnf remove htop -y

To check the version installed:

htop --version

And if you want to monitor only a specific user or process, you can use the filter feature inside htop. Just press / and type your search term.

For users who prefer YUM compatibility mode:

sudo yum install htop -y

This works too, as RHEL 9 supports both yum and dnf.

To make the output more readable with tree-view:

Inside htop, press F5 to toggle tree view and F6 to sort by CPU, memory, etc.
