Linux is a growing number of operating systems meant to run in computers, phones, and several more electronic devises. Linux was created by Linus Torvalds as a free alternative to Windows. The graphical user interface that runs on Linux is made up of free and open sourced software.

Many people like the command line functionality of the Linux operating system because it is well documented and even has
