Introduction
A utility of the Linux OS is the Linux Command. All primary and advanced tasks can be done by executing commands. The commands are performed on the Linux terminal. The terminal is a command line similar to the command prompt in Windows OS. Commands in Linux are case-sensitive.
It provides a powerful command-line interface compared to other OS like macOS and Windows. We can do basic and advanced work by using its terminal. We can do tasks such as creating, deleting, moving a file, etc. Also, we can do advanced tasks like administrative tasks (including package installation and user management), networking tasks (ssh connection), and many more.
