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:

158  mkdir session_3_practice
  159  touch budget.csv
  160  touch mentors.txt
  161  cd session_3_practice/
  162  mkdir notes
  163  cd ..
  164  cat session_3_practice/
  165  ls
  166  cd session_3_practice/
  167  ls
  168  cd ..
  169  rm budget.csv 
  170  rm mentors.txt 
  171  ls
  172  cd session_3_practice/
  173  ls
  174  touch
  175  ls
  176  touch budget.csv
  177  touch mentors.txt
  178  ls
  179  cd notes
  180  touch git_notes.txt
  181  touch command_line_notes.txt
  182  ls
  183  cd ..
  184  mkdir practice
  185  cd practice/
  186  touch git_practice.txt
  187  mkdir projects
  188  cd projects/
  189  touch game.js
  190  ls
  191  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):

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

No commits yet

Untracked files:
  (use "git add <file>..." to include in what will be committed)

	quotes.txt

nothing added to commit but untracked files present (use "git add" to track)
faerber~/git_homework$ git add quotes.txt 
faerber~/git_homework$ git status
On branch master

No commits yet

Changes to be committed:
  (use "git rm --cached <file>..." to unstage)

	new file:   quotes.txt

faerber~/git_homework$ git commit -m 'Initial commit'

faerber~/git_homework[master]$ echo "Do what is right not what is easiest" >> quotes.txt
faerber~/git_homework[master !]$ git status
On branch master
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

	modified:   quotes.txt

no changes added to commit (use "git add" and/or "git commit -a")
faerber~/git_homework[master !]$ git diff
diff --git a/quotes.txt b/quotes.txt
index e69de29..844fe5c 100644

faerber~/git_homework[master !]$ git add quotes.txt
faerber~/git_homework[master !]$ git commit -m 'Add quote'

faerber~/git_homework[master]$ git status

faerber~/git_homework[master]$ git log --oneline
62b173b (HEAD -> master) Add quote
a24b7b2 Initial commit
faerber~/git_homework[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:

1. For the first practice, I originally built the two files before getting into the directory so I removed them and tried again. For the second practice, I Googled how to show the log in oneline format so I'm not 100% sure that was correct.

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, @hfaerber! It is great practice to have to remove files and then add them in a different place. And good job googling oneline format -- your work is correct!
