Wicked cool shell scripts, 2nd edition (No Starch Press,US)

All computers running Linux, Mac OS X, or Unix-like operating systems have a command line interface that gives users a powerful alternative to managing their computers and learning programming basics. Users can write small programs, or scripts, that run in the command line "shell" to perform everyday tasks like renaming files or processing text. Like the best-selling first edition, this revision of Wicked Cool Shell Scripts provides the full source code for over 100 short shell scripts that solve common problems, can be used to personalize a user's computing environment, and are just plain entertaining. The tools include an interactive calculator, a stock tracker, a password manager, a weather checker, and a website search engine. This revision includes 22 brand-new scripts, a new chapter on image-processing, and a suite of scripts to work with cloud-based services like Dropbox and iCloud.
