One of most popular platforms on the planet, Android, is powered by the Linux Operating System.
An Operating System is software that manages all of the hardware resources associated with your desktop or laptop. To put it simply, the operating system manages the communication between your software and your hardware. Without the operating system ,the software wouldn't function.
Why we use LINUX
Linux is also distributed under an open source license.
The freedom to run the program, for any purpose.
The freedom to study how the program works, and change it to make it do what you wish.
The freedom to redistribute copies so you can help your neighbor.
The freedom to distribute copies of your modified versions to others.
These points are crucial to understanding the community that works together to create the Linux Operating System.
What is Shell Script?
A Shell Script is a text file that contains a sequence of commands for a UNIX based operating system. It is called a shell script because it combines a sequence of commands, that would otherwise have to be typed into the keyboard one at a time, into a single script.
The shell is an operating system's command line interface and interpreter for the set of commands that are used to communicate with the system.
