Introduction to Bash Scripting – Let’s Get Started
In this easy, step-by-step Bash series, we’ll guide you through everything you need to know about Bash scripting.
If you’ve ever used a Linux terminal, you’ve already taken the first step into the world of Bash scripting, whether you realized it or not.
Bash (short for Bourne Again SHell) is the default shell for most Linux systems, which lets you interact with your system using commands, but more importantly, it gives you the power to automate those commands with scripts.
Think of Bash scripts as simple programs you write to make your computer do boring or repetitive tasks for you. Instead of running the same command every day, you can write it once and let the script handle it automatically.
