Why Use Linux

Linux is completely different from other operating systems in many ways.

• It is an open source OS which gives a great advantage to the programmers as they can design their own custom operating systems.
• It gives you a lot of option of programs having some different features so you can choose according to your need.
• A global development community look at different ways to enhance its security, hence it is highly secured and robust so you don’t need an anti virus to scan it regularly. Companies like Google, Amazon and Facebook use linux in order to protect their servers as it is highly reliable and stable.
• Above all you don’t have to pay for software and server licensing to install Linux, its absolutely free and you can install it on as many computers as you want.
• Its completely trouble free operating system and don’t have an issue with viruses, malware and slowing down your computer.

Linux Bash

The Linux Bash is also known as ‘Bourne-again Shell.’ It is a command language interpreter for the Linux based system. It is a replacement of Bourne shell (sh). It was developed under the GNU Project and written by Brian Fox. Nowadays, Bash is the default user shell of most of the Linux distributions.

The Linux/Unix shell allows us to interact with the Linux system through the commands. It let us invoke an executable file to create a running process. Moreover, it also allows us to interact with the Linux file system. It is designed in such a way that we can perform all the Linux operations through Bash.

The Bash is a command language interpreter as well as a programming language. It supports variables, functions, and flow control, like other programming languages. It can also read and execute the commands from a file, which is called a shell script.
