Command-line resources

Here are some things you'll want to keep nearby as you get familiar with Terminal commands and shell scripting: 

• Read The Fantastic Manual! Built-in manuals: man + [command name]

• For any given UNIX command, someone has probably already figured out how to do what you’re trying to do. Search online for [command name] + “UNIX examples”

• The incredibly useful ss64 command-line index (not just Unix / Linux, but also DOS prompt, mysql, and more)

• A directory full of random files and subdirectories for you to download and mess around with

• Quick reference for editing your PATH variable
