→INVESTIGATION 1: ABSOLUTE / RELATIVE / RELATIVE-TO-HOME PATHNAMES
# Now issue the following Linux command using an '''absolute''' pathname: <span style="color:blue;font-weight:bold;font-family:courier;">ls /bin</span><br><br>Which type of pathname would be the best to use in this situation?<br><br>'''NOTE:''' Using the previous command using the '''relative-to-home''' pathname would work,<br> but it would look weird. Try to issue the command yourself!<br><br>
# Let's copy the file called ls which is contained in the '''/bin''' directory to your '''home''' directory by using the '''cp''' command.<br>First, issue the following Linux command to copy the ls command from the /bin directory to your home directory using absolute pathnames:<br><span style="color:blue;font-weight:bold;font-family:courier;">cp /bin/ls /home/youruserid</span><br><br>
# Now let's issue the previous command using just relative pathname (remember, our current directory location is '''examples'''):<br><span style="color:blue;font-weight:bold;font-family:courier;">cp ../../../../../bin/ls ../..</span><br><br>'''TIP:''' For relative pathnames that move up multiple parent directories such as these, it is HIGHLY RECOMMENDED<br>to view the tree diagram and check for the correct number of .. symbols. Students commonly make mistakes <br>and lose marks on these type of questions!<br><br>
# Let's issue the command using one absolute pathname and a relative pathname: <span style="color:blue;font-weight:bold;font-family:courier;">cp /bin/ls ../..</span><br>What did this command do?<br><br>
# Let's issue the same command using one absolute pathname and a relative-to-home pathname: <span style="color:blue;font-weight:bold;font-family:courier;">cp /bin/ls ~</span><br>What did this command do?<br><br>Which of the following file type combinations requires the LEAST number of keystrokes to copy the ls file to your home directory?<br><br>
