Linux Commands

Introduction  

Linux commands are the instructions that are typed into the command line interface (CLI) to perform various tasks in a Linux operating system. The command line is a powerful and flexible way to interact with a Linux system, and allows users to do things that are not possible using the graphical user interface (GUI) alone.

Linux commands are often used by developers and system administrators to automate tasks, configure the system, and perform advanced operations. Some common Linux commands include ls for listing files, cd for changing directories, mkdir for creating directories, and rm for deleting files.

To learn more about Linux commands, you can read the manual pages for each command using the man command. For example, to view the manual page for the ls command, you would run man ls at the command prompt.
