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)

Need help? You can go back to the files/directories portion of the lesson here.

Scroll down to the bottom of this page 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:

 157  mkdir session_3_practice
  158  cd session_3_practice/
  159  mkdir notes mkdir practice
  160  ls
  161  touch budget.csv mentors.txt
  162  ls
  163  cd notes/
  164  touch git_notes.txt command_line_notes.txt
  165  ls
  166  cd ..
  167  cd practice/
  168  mkdir projects
  169  cd projects/
  170  touch game.js
  171  ls
  172  cd ..
  173  touch git_practice.txt
  174  ls
  175  cd../..
  176  cd ../../
  177  history

Since this is just a practice directory, feel free to remove the parent directory session_3_practice 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 quotes.txt 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):

sara~$ mkdir git_homework sara~$ cd git_homework/ sara~/git_homework$ touch quotes.txt sara~/git_homework$ git init Initialized empty Git repository in /Users/sara/git_homework/.git/ sara~/git_homework$ git status On branch master

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

3. Questions/Comments/Confusions

If you have any questions, comments, or confusions that you would an instructor to address, list them below:

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.

Nice work, @slkarsh! Next time try formatting your copy-pasted git code by adding three backtics (key left of the letter one) ``` before and after your code block. This will come in handy when you are trying to Slack people code snippets as well.
