'''Perform the Following Steps:''' # Make certain that you are logged into your Matrix account.<br><br>
# Issue the following command: <span style="color:blue;font-weight:bold">man man</span><br>How many volume numbers are contained in the man pages (like '''executable commands/programs''', '''games''', or '''system administrator commands''')?<br><br>
# Press the letter <span style="color:blue;font-weight:bold">q</span> to exit the man command.<br><br>
