→LAB 3 SIGN-OFF (SHOW INSTRUCTOR): - migrating lab script to a server not behind vpn.
<li>Add a third prompt (immediately after the other two prompts and before the tar command), asking the user if they want the archive to be compressed. You'll need an if statement to run your tar command with gzip compression if they answered yes.</li>
<li>Test your script to make sure it works.</li>
<li>Add a fourth prompt asking the user what type of compression they want (present them with gzip, bzip2, and xz xzip as options). Note that this prompt should only be shown if the user opted for compression (if they don't want compression, there is no point asking what type they don't want).</li>
<li>Expand the if statement around your actual tar command to use whichever type of compression the user asked for.</li>
<li>Test your script to make sure it works.</li>
# Make certain that your '''c7host''' and '''centos3''' VMs are running.
# Switch to your <u>'''c7host'''</u> machine, open a shell terminal as a regular user, and change to the directory: '''~/bin'''
# Download the Lab 3 check script: <b><code><span style="color:#3366CC;font-size:1.2em;">wget https://ictosl740.senecacollegegithub.ca/~ops245io/labs/lab3-check.bash</span></code></b>
# Give the '''lab3-check.bash''' file execute permissions (for the file owner).
# Run the shell script with <code>sudo</code>, and if any warnings appear, fix the issues noted by the script and rerun the check until you receive the "Congratulations!" message.
