Commands

The primary way you interact with a terminal is by running commands.

You start with a blank prompt and write something like the following[^nottyped].

$ echo Hello
Hello

The first word is the name of the program to run. In this case echo. Everything after that is an "argument" to the program.

[^nottyped] You don't actually type the $. That is illustrative. Your terminal will give you something like a $ or a > as a "prompt."
