 <p>Don’t you think your shell looks messy with all of those old prompts? Don’t worry, you’re about to learn your first shell command which will clear up your shell! Type <code>clear</code> at the prompt and then hit enter. Voila! Your shell is back to how you started.</p>
 <p>Every command line command is actually a little computer program, even commands as simple as <code>clear</code>. These commands all tend to have the following structure:</p>
 <pre><code>[command] [options] [arguments]</code></pre>
-<p>Some simple commands like <code>clear</code> don’t require any options or arguments. Options are usually preceded by a hyphen (<code>-</code>) and they tweak the behavior of the command. Arguments can be names of files, raw data, or other options that the command requires. A simple command that has an argument is <code>echo</code>. The <code>echo</code> command prints a phrase to the console. Enter <code>echo &quot;Hello World!&quot;</code> into the command line to see what happens:</p>

 <p>We’ll be using the above syntax for the rest of the book, where on one line there will be a command that I’ve entered into the command line, and then below that command the console output of the command will appear (if there is any console output). You can use <code>echo</code> to print any phase surrounded by double quotes (<code>&quot;&quot;</code>) to the console.</p>
 <p>If you want to see the last command press the <code>Up</code> arrow key. You can press <code>Up</code> and <code>Down</code> in order to scroll through the history of commands that you’ve entered. If you want to re-execute a past command, you can scroll to that command then press <code>Enter</code>. Try getting back to the <code>echo &quot;Hello World!&quot;</code> command and execute it again.</p>
