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:

noahgibson~$ cd
noahgibson~$ mkdir session_3_practice
noahgibson~$ ls
Applications		Library			Public
Desktop			Movies			session_3_practice
Documents		Music
Downloads		Pictures
noahgibson~$ cd session_3_practice
noahgibson~/session_3_practice$ touch budget.csv
noahgibson~/session_3_practice$ touch mentors.txt
noahgibson~/session_3_practice$ ls
budget.csv	mentors.txt
noahgibson~/session_3_practice$ mkdir notes
noahgibson~/session_3_practice$ ls
budget.csv	mentors.txt	notes
noahgibson~/session_3_practice$ cd notes
noahgibson~/session_3_practice/notes$ touch git_notes.txt
noahgibson~/session_3_practice/notes$ touch command_line_notes.txt
noahgibson~/session_3_practice/notes$ cd ..
noahgibson~/session_3_practice$ mkdir practice
noahgibson~/session_3_practice$ cd practice
noahgibson~/session_3_practice/practice$ touch git_practice.txt
noahgibson~/session_3_practice/practice$ ls
git_practice.txt
noahgibson~/session_3_practice/practice$ mkdir projects
noahgibson~/session_3_practice/practice$ cd projects
noahgibson~/session_3_practice/practice/projects$ touch game.js
noahgibson~/session_3_practice/practice/projects$ ls
game.js
noahgibson~/session_3_practice/practice/projects$ 

or 

 mkdir session_3_practice
   61  ls
   62  cd session_3_practice
   63  touch budget.csv
   64  touch mentors.txt
   65  ls
   66  mkdir notes
   67  ls
   68  cd notes
   69  touch git_notes.txt
   70  touch command_line_notes.txt
   71  cd ..
   72  mkdir practice
   73  cd practice
   74  touch git_practice.txt
   75  ls
   76  mkdir projects
   77  cd projects
   78  touch game.js
   79  ls
   80  cd
   81  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):

noahgibson~$ mkdir git_homework
noahgibson~$ cd git_homework
noahgibson~/git_homework$ touch quotes.txt
noahgibson~/git_homework$ ls
quotes.txt
noahgibson~/git_homework$ git init

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.
