The Art of Command Line

Learn the command line on one page.

This guide is the result of many authors and translators and created for both beginners and experienced users.

The goals:

breadth (everything important);
specificity (give concrete examples of the most common case);
brevity (avoid things that aren't essential or digressions you can easily look up elsewhere).

Every tip is essential in some situation or significantly saves time over alternatives.
The focus is on interactive Bash, though many tips apply to other shells and to general Bash scripting.
It includes both "standard" Unix commands as well as ones that require special package installs -- so long as they are important enough to merit inclusion.
