The author starts with a foundation of the terminal and then build opon layers on top where objects learned earlier are applied and things get more elaborate. Recommend Armin’s books and the blog for every Mac Admin. The book (as well as others from Armin) are well written.

Not until you read this book. Was sold after reading just the sample pages and realizing I didn’t know how much I didn’t know. Approaching 200 pages in and the facepalm moments and “try this” notes I’ve tagged throughout are too many to count. Love his blog, and appreciate all the free education Armin provides the world. Bought ALL of his Apple Books last week as a way of giving back - of course also with the intention of reading every page of every one of them. Thank You, Armin!

This is an excellent primer and reference on using the Terminal and shell scripting on macOS. I own and recommend all of Armin’s books, along with his blog and weekly newsletter. They are all valuable resources for the Apple ecoverse administrator/engineer.

For beginners and “seasoned” Mac Admins alike, Armin combines detailed explanations with real-world examples to help everyone increase their comfort level and productivity with Terminal and shell.

I’ve been administering macOS systems for quite some time, and I spend a lot of time in terminal and writing bash scripts. I have found so much new information in this book to help me understand how and why things happen, as well as details I wasn’t aware of to streamline workflows and scripts I’ve implemented. I highly reccomend this to any mac admin, even if you’re somewhat well versed you will find things to refer to and details ou may not have been aware of.
