So, you want to learn shell scripting? Or perhaps you want to improve your existing bash knowledge? I have collected a few resources that will help you learn shell scripting for free.
A shell is a command-line interpreter that lets you type in commands to get an output. You’re already looking at a shell when you’re using the terminal.
Yes, a shell is a command-line interface that you can interact with to give some type of instructions to the operating system. While there are different types of shells, bash (GNU Bourne-Again Shell) is the popular one used by almost every Linux distro out there.
When talk about shell scripting, that means — a user wants to execute multiple commands to get an output using a script.
You may need to learn shell scripting as part of your course curriculum or as part of your job. Knowing shell scripting also helps you automate certain repeated tasks in Linux.
Whatever be the reason for learning shell scripting, let me show you the resources.
