==Part 1: Automating Routine Tasks (Shell Scripting)==
[[Image:lab2_text_1.png|thumb|right|275px|When executed as '''root''' or using '''sudo''' command, provides VM status and opportunity to '''start''' VMs in a text-based interface]]
We continue the discussion of using Bash Shell Scripts to help automate routine tasks for the Linux system administrator. In lab1, you were exposed to downloading and running Bash Shell Scripts for demonstration purposes. Before showing you demos for this lab, you should learn a few more "shell scripting tricks" in case you need to create your own set of tools for task automation.
#Click on the following link to run an online tutorial showing you some additional shell scripting techniques: [ link ].
#It is recommended to practice creating Bash Shell Scripts as you proceed throughout this course.
#Let's look at some demos involving managing VMs with shell scripts. Issue the following command:<blockquote><b><code><span style="pointer-events: none;cursor: default;color:#3366CC;">wget https://scs.senecac.on.ca/~elizabeth.kopiec/backupVM.bash</span></code></b></blockquote>
#Set the appropriate permissions and run this Bash Shell script.
#Verify that the backup of your virtual machine occurred (hint: issue ls command to verify the date and time of creation).
#Use the <b><code>wget</code></b> command to download, study, and run the following shell scripts on-line:<blockquote><b><code><span style=" pointer-events:none;cursor:default;color:#3366CC;">https://scs.senecac.on.ca/~murray.saul/vm-start-text.bash<br>https://scs.senecac.on.ca/~murray.saul/vm-stop-text.bash</span></code></b><br><b><code><span style=" pointer-events:none;cursor:default;color:#3366CC;">https://scs.senecac.on.ca/~murray.saul/vm-start.bash<br>https://scs.senecac.on.ca/~murray.saul/vm-stop.bash</span></code></b></blockquote>
#Try to understand what these Bash Shell scripts do.
