Linux is an open-source Operating System which is released with different flavours (or distros) under the guise of free-to-use software. Anybody can download and run Linux free-of-charge and with no restraints on the end-user; you could release, distribute and profit from Linux with relative ease with no worry of associated cost or licensing infringement. It is fair to say Linux has formidably and profoundly revolutionised and defined the process of interacting with electronic devices. You can find Linux in cars, refrigerators, televisions and of course, as a desktop-grade or headless operating system. Once you become accustomed to Linux, you quickly see just why all the top 500 supercomputers all run Linux.

If you’ve ever used a Linux operating system used on most Virtual Private Servers, you may have heard of bash. It’s a Unix shell that reads and executes various commands. Bash, short for Bourne-Again Shell, is a Unix shell and a command language interpreter. It reads shell commands and interacts with the operating system to execute them. Why Use Bash Scripts? Bash scripts can help with your workflow as they compile many lengthy commands into a single executable script file. For example, if you have multiple commands that you have to run at a specific time interval, you can compile a bash script instead of typing out the commands manually one by one. You then execute the script directly, when it’s necessary.
