Commands and Other Terminal Text
Commands or command parameters that you might type, along with other text that normally appears in a Terminal window, are shown in this font. For example,
You can use the doit command to get things done.
When a command is shown on a line by itself as you might type it in a Terminal window, it follows a dollar sign that represents the shell prompt. For example,
$ doit
To use this command, type “doit” without the dollar sign at the command prompt in a Terminal window, then press the Return key.
Command Parameters and Options
Most commands require one or more parameters to specify command options or the item to which the command is applied.
