In this tutorial, we will explain the most common bash operations while also showing you a few bash script examples.
A Unix shell program interprets instructions and programs in the form of commands. These commands are either directly entered by the user, or they can be run in sequence from a file (called a shell script). An important distinction of bash scripts when compared to other coding languages is that they are interpreted and not compiled. When you write a shell script and then run it, it’s interpreted by your operating system, with no compilation required.
Bash scripts are a versatile and handy tool that most system administrators love using to simplify their workflow and automate repetitive tasks. With scripts, you can do almost anything that you can do using a normal shell environment.
