=== Purpose / Objectives of Lab 3 ===
In this lab, you will practice working with the Linux command line by manipulating the file system in two separate investigations.
If you encounter technical issues, please contact your professor via e-mail or in your section's Microsoft Teams group.
=== Minimum Requirements ===
Before beginning, you must have:
# Successfully completed [[OPS705_Lab_1 | Lab 1]]
# Watched the Week 3 video lecture
# Read through the Week 3 slides, and have them handy as a reference for concepts
# Your Seneca Azure login credentials
# Your linked mobile device for 2FA
= INVESTIGATION 1: Create the Directory Structure =
[[Image:Ops705_lab3_fig1.png|thumb|right|250px|Figure 1. Square icons are directories, oval icons are empty text files.]]
In this investigation, you'll create the directory structure and text files you see in the tree diagram below. You will do so entirely on the command line using the utilities and command provided to you in the Week 2 lecture.
You work will be done entirely in your home directory.
To begin:
# Start your CentOS Linux VM in Azure (this may take a few minutes)
# Connect to the VM remotely using SSH
# Navigate to your home directory with this command: <code>cd ~</code>
# In your home directory, recreate the directory tree in Figure 1. ''yourusername'' should be your own username home folder that already exists.
# To prove you've completed this section, run the following: <code>echo "My name is ''insertFullName'', and I've completed the CentOS VM investigation." > ~/yourusername_lab2.txt</code>
= INVESTIGATION 2: Moving Files =
In this investigation, you're tasked with moving a set of existing files. You will download and run a script, which will create a set of files in '''~/tmp'''. It is then your job to create the directory structure seen in Figure 2, and move the files from '''~/tmp''' to their proper location according to the file tree diagram. '''Do not delete and recreate files, and do not delete your work from Investigation 1.'''

# On your Linux VM, from your home directory, download script for this lab with the following command: <code>wget https://ict.senecacollege.ca/~chris.johnson/ops705/lab3_script.bash</code>
# Give the script execute permissions: <code>chmod u+x ~/lab3_script.bash</code>
# Run the script: <code>~/lab3_script.bash</code>
# Check that the files 13-17 have been created in '''~/tmp''' (These ''must'' come from the script, do not create them yourself)
# Using Figure 2 as a model, create the '''~/shared''' directory structure
# Using Figure 2 as a model, move the files from '''~/tmp''' to their proper location in '''~/shared'''
= Lab Submission =
Submit to Blackboard's ''Lab Submission'' section full-desktop screenshots (PNG/JPG) of the following:
# From your home directory, run <code>tree</code>. Your screenshot should contain the entire output. (To install tree, run: <code>sudo yum install tree</code>)
# Run the following command and screenshot: <code>hostnamectl</code>
Your professor will review your VMs directly; the screenshots are a backup in case of catastrophic issues.
'''Your professor will not check your lab until the screenshots have been submitted.'''
Make sure to fully stop your VMs when you're done!
