Session 3 Practice Tasks

The assignments listed here should take you approximately 25 total minutes.

To start this assignment, click the button in the upper right-hand corner that says Fork. This is now your copy of the document. Click the Edit button when you're ready to start adding your answers. To save your work, click the green button in the bottom right-hand corner. You can always come back and re-edit your gist.

1. Creating Files and Directories (10 min)

You can reference the files/directories portion of the lesson here.

Scroll down to the bottom and look at the image of the directories and files. Use commands in your terminal to create the directories and files structured exactly how they appear in the image.

When you're done, type history to see your commands. Copy and paste the commands that were used to create the directory and files:

Last login: Tue Jan 29 18:42:40 on ttys000
katherin~ mkdir turing
katherin~ cd turing
katherin~/turing touch budget.txt
katherin~/turing touch mentors.txt
katherin~/turing ls
budget.txt	mentors.txt
katherin~/turing mkdir mod_0
katherin~/turing touch git_notes.txt
katherin~/turing touch oop_notes.txt
katherin~/turing cd ..
katherin~ cd turing
katherin~/turing mkdir prework
katherin~/turing cd prework
katherin~/turing/prework touch assignment_list.txt
katherin~/turing/prework mkdir projects
katherin~/turing/prework cd projects
katherin~/turing/prework/projects touch game.js
katherin~/turing/prework/projects ls
game.js
katherin~/turing/prework/projects

Since this is just a practice directory, feel free to remove the parent directory turing when you're done with this exercise.

2. Git Practice (15 min)

You can reference the files/directories portion of the lesson here.

Follow the steps below to practice the git workflow. Be ready to copy-paste your terminal output as confirmation of your practice.

1. Create a directory called git_homework. Inside of there, create a file called quotes.txt.
2. Initialize the directory
3. Check the git status
4. Add your notes file to the staging area
5. Check the git status
6. Create an initial commit
7. Check the status
8. Add your favorite quote to the quotes.txt file
9. Check the status
10. Check the diff
11. Add the changes to the staging area
12. Commit the new changes
13. Check the status
14. Show the log in oneline format

Copy and paste all of the terminal text from this process below (not just the history):

Last login: Wed Jan 30 21:09:02 on ttys000
katherin~ mkdir git_homework
katherin~ cd git_homework
katherin~/git_homework touch quotes.txt
katherin~/git_homework git init

IMPORTANT: Do not remove this git_homework directory. You will be using this directory during Thursday's session.

Extensions

1. If time permits and you want extra git practice and alternative explanations (it's often beneficial to have something explained in many different ways), check out Codecademy's Git Course, particularly the first free item on the syllabus, "Basic Git Workflow". In Mod 0, we will not cover anything beyond Codecademy's intro section; however, you are welcome to check out the other git lessons listed on the syllabus if you want a head start.

2. This course is how I personally learned command line. If time permits, I highly recommend reading and practicing.

3. Also recommended by Jeff Casimir: Michael Hartl's Learn Enough Command Line.

4. Add tab completion to make your life easier: Type Less. Do More.
