Shell scripts are an efficient way to interact with your machine and manage your files and system operations. With just a few lines of code, your computer will do exactly what you want it to do. But you can also use shell scripts for many other essential (and not-so-essential) tasks.

This second edition of Wicked Cool Shell Scripts offers a collection of useful, customizable, and fun shell scripts for solving common problems and personalizing your computing environment. Each chapter contains ready-to-use scripts and explanations of how they work, why you’d want to use them, and suggestions for changing and expanding them. You’ll find a mix of classic favorites, like a disk backup utility that keeps your files safe when your system crashes, a password manager, a weather tracker, and several games, as well as 23 brand-new scripts, including-

• ZIP code lookup tool that reports the city and state
  
• Bitcoin address information retriever
  
• suite of tools for working with cloud services like Dropbox and iCloud
  
• for renaming and applying commands to files in bulk
