# Issue a Linux command to confirm that those directories have been created<br>(you should already know how to do this).<br><br>There are better ways to create the same directory structure without using the '''cd''' command.<br><br>Issuing the '''cd''' command '''<u>prior</u>''' to issuing other commands indicates to others that you are a novice or "'''newbie'''".<br>You can actually '''lose marks''' on quizzes or examples if you issue multiple Linux commands to performed tasks that can be performed<br>using a single Linux command with '''pathnames'''.<br><br>
# Issue the following Linux command to return to your home directory: <span style="color:blue;font-weight:bold;font-family:courier;">cd</span><br><br>
# Issue a Linux command to confirm that you are now located in your home directory.<br><br>Although we will teach you how to '''remove''' directories and their contents in another sectioninvestigation,<br>let's remove the created directory structure' and '''recreate''' the same directory structure<br>using just <u>one</u> command using pathnames.<br><br>
# Issue the following Linux command to remove all of the directories that you have created:<br><span style="color:blue;font-weight:bold;font-family:courier;">rm -r uli101xx acp100xx xyz100xx</span><br><br>
# Issue a Linux command to confirm that the '''uli101xx''', '''acp100xx''' and '''xyz100xx''' that been removed.<br><br>

# If you encounter errors, then view the feedback to make corrections, and then re-run the checking script. If you receive a congratulation message that there are no errors, then proceed to the next sectionpart.
