How To Xclock In Linux

Whether you are a seasoned Linux user or just a beginner, dealing with the command line tools can sometimes be a bit challenging. One such handy tool that you may need to use is the Xclock. This blog post aims to provide a detailed guide on how to use Xclock in Linux.

What is Xclock?

The xclock program in Linux is a handy utility that displays the time in analog or digital form. It is a simple, lightweight application that doesn’t consume much system resources. The clock can be customized with a variety of options, and can be useful for quickly checking the time while you’re working within a terminal.

How to install Xclock

Before we can use Xclock, we need to install it first. On most Linux distributions, Xclock is included by default. However, if your system does not have it, you can easily install it using the package manager of your Linux distribution.

For Ubuntu and other Debian-based distributions, use the following command:

sudo apt-get install x11-apps

For CentOS, Fedora, and other RHEL-based distributions, use the following command:

sudo yum install xorg-x11-apps

Running Xclock

Once you have Xclock installed, running it is as simple as typing xclock in your terminal:


This will open a simple analog clock on your screen.

Customizing Xclock

Xclock comes with several command-line options that allow you to customize its display. For example, you can display the clock in digital form by using the -digital option:

xclock -digital

This will display a digital clock instead of an analog one.

There are many other command-line options available for Xclock, allowing you to change the font, color, size, and many other aspects of the clock. For a full list of available options, you can check the man page of Xclock by typing man xclock in your terminal.


Although it might look like a simple utility at first, Xclock can be a very useful tool if you spend a lot of time working in a terminal. It is lightweight, easy to use, and highly customizable, making it a great addition to any Linux user’s toolbox.
