Most used commands in Linux.

 

Commands in Linux are utilities that allow users to perform basic and advanced tasks on the operating system. These commands are executed on the Linux terminal, which provides a command-line interface for users to interact with the system. The terminal in Linux is similar to the command prompt in Windows OS. It's worth noting that the commands in Linux are case-sensitive, and users must be careful with the spelling and capitalization of the commands they enter.
