It doesn\u2019t matter whatever system you\u2019re using \u2013 Windows, Linux or macOS or whatever, having a handy task manager is always a privilege as it allows you get even more control over the system. That\u2019s why there are a number of reasons I love to have Htop at my disposal.<\/p>\n

Htop is a great, interactive system monitor and process manager that targets the UNIX systems. Of course, it\u2019s a CLI tool that uses the text-mode. For using Htop, you need to have \u201cncurses\u201d present in your system.<\/p>\n

This is a very powerful solution for the enterprise and server areas where GUI is mostly avoided. Granted, GUI tools are more awesome-looking and easier-to-use for any user but for pro and server managers, the CLI is the best way to go.<\/p>\n

In the case of CentOS \u2013 the free edition of Red Hat Enterprise Linux, is the testing ground of the original condition of the server and enterprise. Today, let\u2019s have a look at the installation and usage of Htop on CentOS.<\/p>\n

Htop is already available at the Fedora EPEL repository and it\u2019s officially maintained. THat\u2019s why this is the most recommended way of getting htop. Don\u2019t worry; if you wish, you can also download the source and compile it by yourself.<\/p>\n

1) Installing from EPEL<\/h2>\n

Make sure that your system has enabled the EPEL repository \u2013<\/p>\n

sudo yum install epel-release
\nsudo yum update’<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

Once EPEL is ready, it\u2019s time to install htop \u2013<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

2) Installing from source<\/h2>\n

At first, make sure that your system includes the \u201cDevelopment Tools\u201d \u2013<\/p>\n

sudo yum groups mark install “Development Tools”
\nsudo yum groups mark convert “Development Tools”<\/p>\n

\"\"<\/p>\n

sudo yum groupinstall \u201cDevelopment Tools\u201d
\nsudo yum install glibc-devel glibc-headers kernel-headers kernel-devel gnutls-devel<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

sudo yum install ncurses-devel<\/p>\n

\"\"<\/p>\n

Now, download the latest source code of htop<\/a> \u2013<\/p>\n

\"\"<\/p>\n

tar -xvzf htop-2.2.0.tar.gz<\/p>\n

\"\"<\/p>\n

Start the building process \u2013<\/p>\n

\"\"\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

Htop usage<\/h2>\n

Fire up the tool \u2013<\/p>\n

\"\"<\/p>\n

This is the window where you\u2019ll find out every single information about your system.<\/p>\n

On the top, you can check out the memory and swap usage.<\/p>\n

\"\"<\/p>\n

For entering the setup, press F2.<\/p>\n

\"\"<\/p>\n

Here, you can easily check out what options and info are available on the main window.<\/p>\n

Tree view<\/h4>\n

It\u2019s my favorite view as it allows you to understand the hierarchy of each process with ease. Press F5 or \u201ct\u201d.<\/p>\n

\"\"<\/p>\n

Killing a process<\/h4>\n

Select a process and hit F9 or \u201ck\u201d button.<\/p>\n

\"\"<\/p>\n

Then, select \u201cSIGKILL\u201d.<\/p>\n

\"\"<\/p>\n

You can also perform multi-kill. Use \u201cSpacebar\u201d for tagging all the processes you want to kill and then,<\/p>\n

Processes from a single user<\/h4>\n

On the main window, hit \u201cu\u201d key.<\/p>\n

\"\"<\/p>\n

Then, select the user you want to see.<\/p>\n

\"\"<\/p>\n

Monitor a particular process<\/h4>\n

Highlight the process and hit \u201cF\u201d.<\/p>\n

\"\"<\/p>\n

The highlighting will change the highlighting of the process.<\/p>\n

For all the other usage, check out the man page of htop \u2013<\/p>\n

\"\"<\/p>\n

Or, the htop help page \u2013<\/p>\n

\"\"<\/p>\n

Enjoy!<\/p>\n
