Linux, an operating system, requires some network commands that direct it to perform specific tasks or show certain details. Generally, the Linux commands we give to the operating system to perform the requested tasks are giving commands. These commands are typed in the Linux terminal and granted individually, consuming more time and comparatively tricky.

Bash scripting or Shell scripting is a programming system where we create a specific file, and on an orderly basis, we place one after the other Linux command, we recognize these commands in one single file. Then, the specific file is transformed in the form of scripts. By doing so, we can easily activate or command our shell interpreters to execute the commands altogether.
