Linux is a popular open-source operating system that is widely used for servers, desktops, and other devices. One of the key features of Linux is its powerful command-line interface, which allows users to perform various tasks and manage the system efficiently.
The Linux command line consists of a shell, which is a program that reads and executes commands. There are several shells available in Linux, including the most commonly used Bourne Again SHell (BASH). The shell accepts commands entered by the user and executes them, either by running a built-in command or by calling an executable file.
Some of the most commonly used Linux commands include ls, which lists the contents of a directory, cd, which changes the current working directory, and pwd, which prints the current working directory. The touch command creates a new file or updates the modification time of an existing file, while the rm command removes files or directories. The cat command concatenates and displays files, while the echo command displays a message or the value of a variable. See the bellow commands that are commonly used.
