→INVESTIGATION 1: ABSOLUTE / RELATIVE / RELATIVE-TO-HOME PATHNAMES
# '''Login''' your matrix account.<br><br>
# Issue a command to '''confirm''' you are located in your home directory.<br><br>Let's create the following directory structure under your home directory by issuing the mkdir command using only absolute pathnames.<br><br>'''NOTE:''' The command you issue below will be VERY LONG... just keep typing and let the text continue of separate lines. When using these absolute pathnames, start each one from the root directory (/) and replace the text "youruserid" with your actual login id.<br><br>
# Issue the following Linux command to create the directory structure displayed to the right using all '''absolute pathnames''':<br><br><span style="color:blue;font-weight:bold;font-family:courier;">mkdir -p /home/youruserid/tutorial3/practice/commands /home/youruserid/tutorial3/practice/examples /home/youruserid/tutorial3/notes/lesson1 /home/youruserid/tutorial3/notes/lesson2</span><br><br>Let's remove this directory structure, and issue the same command using a relative-to-home pathname.<br><br>
# Issue the following Linux command (enter "y" at each prompt to remove ALL contents):<br><span style="color:blue;font-weight:bold;font-family:courier;">rm -ri /home/youruserid/tutorial3</span><br><br>
# Issue a command to confirm that the tutorial3 directory (and its contents) no longer exist. You should know how to do this.<br><br>Let's recreate the same directory structure, but use a relative-to-home pathname. You usually generate the ~ character by Holding down '''SHIFT''' and press the button to the left of the number '''1''' above the text on your keyboard.<br><br>
