Top 5 Shell Scripting Books for Beginners in 2021

Being able to write shell scripts is like creating a clone of yourself: you become far more productive.

Being able to write shell scripts is like creating a clone of yourself: you become far more productive.

Shell scripting helps systems administrators and programmers do tedious computer tasks.

We perform small tasks all the time: opening folders, changing directories, gathering information, and editing files. Editing one file at a time for a person can get tedious.

Shell scripting allows you to perform these tasks all at once — almost like dispatching a clone of yourself to do the work.

 

In this article, we’re going over the best books to learn shell scripting. While there are many flavors of command line shells, bash, which is from a Unix environment, is among the most popular.

If you learn to write effective shell scripts and distribute it to your team, you may quickly get recognized for promotion. Everyone loves time savers.

Shell scripting is not only helpful — it is fun and rewarding. Now, let’s look at these books!

 

Why Learn Shell Scripting

Shell scripting is a powerful skill for anyone to adopt to make their systems tasks easier.

Here are a few reasons why you may want to learn shell scripting:

  • Save Time: When you learn to write a shell script, you can automate generic steps that you perform over and over again.

  • Become Highly Valued: If you can cut the time needed to do redundant, computational tasks, your time is freed up for other complex tasks. This can make you highly valued in the work place.

  • Stay Engaged: We feel alive when we are solving real problems. Finding new ways to complete computational tasks keeps you engaged, curious, and energized.

  • Become Entrepreneurial: If you are inspired by the ways automation can work for us, The 4 Hour Workweek set the trend for that vision. If you learn how to think in terms of simplifying redundant tasks, you not only become a better programmer, but you can think of ways to build an online business that mostly runs itself.
