Small, Sharp Software Tools

Harness the Combinatoric Power of Command-Line Tools and Utilities

by

The command-line interface is making a comeback. That’s because developers know that all the best features of your operating system are hidden behind a user interface designed to help average people use the computer. But you’re not the average user, and the CLI is the most efficient way to get work done fast. Turn tedious chores into quick tasks: read and write files, manage complex directory hierarchies, perform network diagnostics, download files, work with APIs, and combine individual programs to create your own workflows. Put down that mouse, open the CLI, and take control of your software development environment.

Customer Reviews

Small, Sharp Software Tools efficiently delivers the practical knowledge you should have if you’re a developer who spends any time at all working at the command line. If you’ve been looking for a text that shows you how to get things done in a Linux or MacOS terminal without slogging through the esoteric things you’ll never use, this is the book you should read.
