→INVESTIGATION 1: ABSOLUTE / RELATIVE / RELATIVE-TO-HOME PATHNAMES
# '''Login''' to 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 '''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>You should notice that using absolute pathnames with this Linux command requires a lot of typing. Let's remove this directory structure, and issue the same command using a ''relative-to-home'' pathnameinstead.<br><br># Issue To remove this directory structure, 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.<br>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>
# Issue the following Linux command to create the same directory structure using relative-to-home pathnames:<br><br><span style="color:blue;font-weight:bold;font-family:courier;">mkdir -p ~/tutorial3/practice/commands ~/tutorial3/practice/examples ~/tutorial3/notes/lesson1 ~/tutorial3/notes/lesson2</span><br><br>Let's remove the '''tutorial3''' directory and its contents and issue the mkdir command with '''relative pathnames''' to create the same directory structure.<br><br>
