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. Now includes complete coverage of Monterey, Big Sur, Catalina, and zsh! Joe includes 67 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. The book begins by teaching you these core concepts: • The differences among Unix, a command line, a shell, and Terminal • Exactly how commands, arguments, and flags work • The basics of Terminal's interface and how to customize it Next, it's on to the command line, where you'll learn: • How to navigate your Mac's directory structure • Basic file management: creating, copying, moving, renaming, opening, viewing, and deleting files • Creating symbolic links • The types of command-line programs • How to start and stop a command-line program • How to edit a text file in nano • How to customize your prompt and other shell defaults • The importance of your PATH and how to change it, if you need to • How to get help (Joe goes way beyond telling you to read the man pages) You'll extend your skills as you discover how to: • Create basic shell scripts to automate repetitive tasks. • Make shell scripts that have variables, user input, conditional statements, loops, and math. • See which programs are running and what system resources they're consuming. • Quit programs that refuse to quit normally. • Enable the command line to interact with the Finder. • Control another Mac via its command line with ssh. • Understand and change an item's permissions, owner, and group. • Run commands as the root user using sudo. • Handle output with pipe (|) or redirect (> or <). • Use grep to search for text patterns in files and filter output. • Install new command-line software from scratch or with a package manager. • Use handy shortcuts in the Terminal app itself and in zsh. Questions answered include: • What changed on the command line in recent versions of macOS? • What are the differences between the zsh shell and the bash shell? • Which shell am I using, and how can I change my default shell? • How do I quickly figure out the path to an item on my Mac? • How can I customize my Terminal window so I can see man pages behind it? • How can I make a shortcut to avoid retyping the same long command? • Is there a trick for entering a long path quickly? • What should I say when someone asks if I know how to use vi? • How do I change my prompt to suit my mood or needs? • What is Command Line Tools for Xcode? • When it comes to package managers, which one should I use? Finally, to help you put it all together, the book showcases 67 real-world "recipes" that combine commands to perform useful tasks, such as listing users who've logged in recently, manipulating graphics, using a separate FileVault password, creating and editing user accounts, figuring out why a disk won't eject, copying the source code of a webpage, determining which apps have open connections to the internet, flushing the DNS cache, finding out why a Mac won't sleep, sending an SMS message, and deleting stubborn items from the Trash.

Unlock the secrets of the Terminal and discover how this powerful tool solves problems the Finder can't handle. With this handy guide, you'll learn commands for a variety of tasks, such as killing programs that refuse to quit, renaming a large batch of files in seconds, or running jobs in the background while you do other work.

Look beyond the basics of Mac programming and development to become a Mac power user. When most people think about the Mac, they think about the amazing graphical user interface macOS is known for. However, there is a whole world to explore beneath the hood. This book approaches working directly in the terminal with fun projects and ideas to help turn you into an advanced Mac user. You'll work with Brew (HomeBrew), which gives you the ability to install applications from Linux (and Unix) that can make the terminal more useful. This is important, because a lot of applications have been stripped out of macOS or deprecated. For example, Apple's built-in PHP is usually a major release behind. You'll also customize your terminal to change everything about it, making it your own. The whole world is about personalizing. Why put up with the Apple defaults? Once you have your terminal set up and ready to rock, you'll review the basics of programming on the Mac terminal. This will allow you to get a taste of power scripting. You'll discover the power of bash, PHP, and Python. And then you'll apply those tools to web development. Tweak Your Mac Terminal takes you on a journey into a world of the terminal and its hidden applications. You will: Customize the terminal to make it perfect for your needs Develop web applications using basic coding skills in the terminal Install HomeBrew and by extension Linux and Unix applications.
