For this assignment, you will be making a basic shell script to make some changes to a file system. A shell script is a useful tool for running multiple terminal commands sequentially. For this assignment, all your answers will be placed in the answers.sh file. Open answers.sh in your favorite text editor to answer (e.g. Notepad, gedit, Visual Studio Code, vim, etc.).
Homework 2 is due on 16 September 2019 at 11:59PM EDT.
-
You will be finished with the assignment when you have a functional SINGLE COMMAND for each of the 12 tasks in your
answers.shfile. -
In order to test your commands, run
bash -i grader.shin terminal. This program will let you know which command is not functionally properly.- Please note that the grade you receive with the
grader.shis not your guaranteed grade on homework 2. Your TA will still go through your commands to ensure that you only use a single command for each of the tasks.
- Please note that the grade you receive with the
-
Open a terminal window
-
Windows: Use Windows Subsystem for Linux (might need some configuration) or Git Bash
-
Mac & Linux: Just open terminal
-
If you are having issues, it might just be easier to use a lab machine in Lawson or Haas
-
-
Click the green "Clone or download" button on this GitHub repository and copy the URL.
-
In terminal, run
git clone URL, replacing URL with what you copied in step 2. (It will ask for GitHub credentials) -
You are ready to go! Start typing your answers in
answers.sh.
ALL COMMANDS SHOULD BE FROM THE ORIGIN DIRECTORY!!!!!
For instance mv Hello.java Hello2.java would not be an acceptable answer for renaming Hello.java to Hello2.java, since there does not exist Hello.java in the ORIGIN directory. Instead, the proper answer would be mv Programs/Hello.java Programs/Hello2.java.
EVERY ANSWER SHOULD ONLY BE A SINGLE COMMAND!!!!!
Rename Homework/MA165/HW2.txt to HW1.txt.
Delete Memes/Spongebob/money.jpeg (it wasn't funny enough to make it into the memes folder).
Move fafsa.jpg from the Star Wars meme folder to Memes/Spongebob (Spongebob memes don't belong in the Star Wars folder).
Delete the Homework/CS191 directory.
Make a new directory in Programs called C++.
Move Programs/Age.cpp to the newly created C++ directory made in Task 2.
Copy the Programs/Java directory into the Homework/CS180 folder, while renaming the Java directory Project_1.
Move Programs/Count.c and Programs/Goodbye.c to the Programs/C directory.
Move Programs/Name.py and Programs/Space.py to the Python 3 folder in the Programs directory.
Make a new file in Homework/POL141 called Essay.txt.
List the files and directories above the current working directory.
Create an alias wttr for the command curl wttr.in. You will need to create the alias in your .bashrc or .bash_profile (macOS only) in order to pass the test case in grader.sh. To get the homework points, please put the command you used to create the alias under # Task 12 in answers.sh.
-
Make sure all your commands are saved in
answers.sh! -
Run
./turn-in.sh(it will ask for your GitHub username and password) -
Verify that your answers have been submitted by opening your GitHub repository online and checking the
answers.shfile. -
You are done! Yay!!!

Simply run ./clean.sh. This will reset your ORIGIN directory without deleting your answers in answers.sh. It is like nothing ever happened!
Take a look at the Terminal_Guide.md file in the repository. This document reviews the content found in lecture. Everything you need to complete this assignment can be found there.
Try different things out by typing out commands in terminal. It is okay to mess up. Simply run ./clean.sh to revert any changes. The best way to learn is to experiment!
If you need extra help, ask a TA, ask on Piazza, or Google around. DO NOT COPY DIRECTLY FROM ANOTHER STUDENT
