What you need to do?

This assignment has two tasks. Your first task is to setup your computer to be able to run the required softwares for the course. In the second task, you'll learn about a few basic functions to work with the Terminal/Shell.

Step 1: Setup Your Computer

Follow the instructions for setting up your computer based on the Operating System you have.

Windows

Install Windows Subsystem for Linux (WSL1 or WSL2) and then install Ubuntu 18.04 or 20.04. Now, install XMing so that you can forward your display. Alternatively (use only one of the two methods), you can also utilize a Virtual Machine (VM) to run Ubuntu. If you want to use the Virtual Machine method, I recommend using VirtualBox. The WSL method is better for performance but the VM method is easier to install. Inside the Ubuntu environment (WSL or VM), install the following packages Python >=3.8, python-opencv, av and the following Python-pip packages numpy, scipy.

Linux (My Preferred OS!)

Install the following packages Python >=3.8, python-opencv, av and the following Python-pip packages numpy, scipy.

MacOS (Intel/AMD)

Install XCode and then the following packages Python >=3.8. Now, install the following Python-pip packages av, opencv-python, numpy, scipy.

.

MacOS (M1 or M1 Pro or M1 Max)

Install the UTM Virtual Machine (VM) with Ubuntu 20.04 from here (recommended) or Parallels . Now follow the instrctions on Linux inside your Virtual Machine.

Step 2: Learn Basic Terminal/Bash functions

Find answers to the following questions using the Terminal/Bash (for WSL's terminal (Ubuntu) if using Windows, native terminal if using Linux/MacOS or VM's terminal), you'll need to make a document to fill in the answers. More details about the submission is given in the next section.

• How do you run a command with superuser access?
• How do you list (a) only non-hidden files?, (b) non-hidden and hidden files?
• When you list files, how do you distinguish between files and folders?
• How do you (a) Change directory to any location?, (b) Change directory to home location?, (c) Change directory to one level up/previous?
• How do you (a) Make a folder?, (b) Make a folder with sub-folders?
• How do you (a) Remove a file?, (b) Remove all files in a folder? (BE SUPER CAREFUL WHEN RUNNING THESE COMMANDS! IT CAN WIPE YOUR ENTIRE HARD-DRIVE!)
• How do you (a) Move a file from one location to another?, (b) Move a folder from one location to another?
• How do you (a) Copy a file from one location to another?, (b) Copy a folder from one location to another?
• How do you display the contents of a file on the terminal?
• How do you know the current working directory path?
• How do you clear the contents of the terminal?

What you need to submit?

A document (feel free to use Word or Google Docs or any other software for this) converted to PDF with the following answers:

• One or multiple screenshots with the outputs (a screenshot is not a photo from your phone) of the following commands in Python environment after importing cv2, numpy, scipy, av.
  • cv2.__version__
  • numpy.__version__
  • scipy.__version__
  • av.__version__
  If any of the above commands throw an error, you have not installed the respective package correctly.
• Answer all the questions in Step 2 in the same document.
• Positive or Negative feedback about this assignment if you have any.
• Challenges you faced in solving this assignment along with lessons learned.

IMPORTANT NOTE: The submissions are made through ELMS with the name ASN1_DirID.pdf. Here, DirID is your directory ID, i.e., the first part of your terpmail email address. For e.g., if your terpmail email address is ABCD@terpmail.umd.edu, then your DirID is ABCD. Keep your submissions professional, grammatically correct without spelling mistakes. Do not use slangs and chat shorthands on your submissions. You'll get 25% grade penalty for not following the submission guidelines.
