UNIX and Linux are operating systems that can support a graphical user interface (GUI) in addition to a command-line interface (CLI). A GUI is a type of user interface that allows users to interact with a computer using visual elements such as icons, menus, and windows. A CLI is a type of user interface that allows users to enter commands using text input.
While UNIX and Linux can support a GUI, they do not come with a GUI installed by default. Instead, they come with a CLI, which allows users to interact with the operating system using text commands.
To use a GUI with a UNIX or Linux system, you will need to install a desktop environment, which is a software package that provides a GUI and a set of tools for interacting with the operating system. There are several desktop environments available for UNIX and Linux, including:
GNOME: A popular desktop environment that is easy to use and highly configurable.
KDE: Another popular desktop environment that is known for its customization options and feature-rich interface.
Xfce: A lightweight desktop environment that is designed to be fast and low on system resources.
To install a desktop environment on a UNIX or Linux system, you will need to use a package manager such as apt-get on Debian or Ubuntu systems or dnf on CentOS or Red Hat Enterprise Linux (RHEL) systems.
Once a desktop environment is installed, you can use it to access and interact with the operating system using a GUI, rather than using text commands in the CLI.
