Command line

Quick Definition

A command line (sometimes called a "console" or "command prompt") is a special text only interface that most operating systems have hidden away somewhere. These interfaces work by having the user enter a single command and then hit ENTER to execute it. In other words, each command is entered on its own line.

Note that while doing things on the command line can be easier than doing them using other tools, it's not really something a novice should be playing with. The command line expects the user to know what they are doing, and several commands can really damage your system or your documents.
