Beginner's Guide to GNU/Linux Scripting
Beginner's Guide to GNU/Linux Scripting
Learn bash and the Unix core utilities in a relaxed way
About the Book
Have you ever used the command line interface on Linux or Mac? Did you feel comfortable in front of that black screen with a unfriendly prompt staring at you and waiting for instructions that you don't know how to give?
The Linux terminal is among the most powerful tools that you can have under your belt. It is extremely useful for developers and a mandatory step for anyone who wants to learn DevOps. Bash and the GNU utilities are two of the major players in the scripting world, and have been simplifying the work of developers and platform engineers around the world for the last 40 years. On top of that, you can find them in every Linux distribution and they can also be installed on MacOS.
This book will introduce you to this new amazing world step by step with a series of 20 slow-paced and focused lessons. Each lesson is meant to be 1 hour of work or less and, while it builds on the previous ones, it is self-contained.
This means that you can allocate just 2 hour a week and in less than 3 months become comfortable in front of the prompt, level up your knowledge of the Linux system, and start being more and more productive in your daily job.
