Version 3.2, updated April 13, 2022

If you've ever thought you should learn to use the Unix command line that underlies macOS, or felt at sea when typing commands into Teal, Joe Kissell is here to help! With this book, you'll become comfortable working on the Mac's command line, starting with the fundamentals and adding more advanced topics as your knowledge increases.

Joe includes 66 real-life "recipes" for tasks that are best done from the command line, as well as directions for working with permissions, carrying out grep-based searches, creating shell scripts, and installing Unix software.
