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:

mkdir session_3_practice
   87  ls
   88  cd session_3_practice
   89  touch budget.csv
   90  touch mentors.txt
   91  ls
   92  mkdir notes
   93  cd notes
   94  touch git_nots.txt
   95  touch command_line_notes.txt
   96  ls
   97  rm git_nots.txt
   98  touch git_notes.txt
   99  ls
  100  cd..
  101  cd ..
  102  mkdir practice
  103  touch git_practice.txt
  104  mkdir projects
  105  touch game.js
  106  ls
  107  rm -rf projects
  108  rm game.js
  109  ls
  110  rm git_practice.txt
  111  ls
  112  cd notes
  113  touch git_notes.txt
  114  touch command_line_notes.txt
  115  ls
  116  cd ..
  117  ls
  118  cd practice 
  119  touch git_practice.txt
  120  ls
  121  mkdir projects
  122  cd projects
  123  touch game.js
  124  ls
  125  cd
  126  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.

Create a directory called git_homework. Inside of there, create a file called quotes.txt.
Initialize the directory
Check the git status
Add your quotes.txt file to the staging area
Check the git status
Create an initial commit
Check the status
Add your favorite quote to the quotes.txt file
Check the status
Check the diff
Add the changes to the staging area
Commit the new changes
Check the status
Show the log in oneline (yes, oneline, not a spelling error) format

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

benfirth~$ mkdir git_homework
benfirth~$ cd git_homework
benfirth~/git_homework$ touch quotes.txt
benfirth~/git_homework$ git init
Initialized empty Git repository in /Users/benfirth/git_homework/.git/
benfirth~/git_homework$ git status

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)
benfirth~/git_homework$ git add quotes.txt
benfirth~/git_homework$ git status

	new file:   quotes.txt

benfirth~/git_homework[master]$ echo "Climb with honor. - Will Anglin" >> quotes.txt
benfirth~/git_homework[master !]$ git status

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")
benfirth~/git_homework[master !]$ git diff
diff --git a/quotes.txt b/quotes.txt

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

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.
This course is how I personally learned command line. If time permits, I highly recommend reading and practicing.
Also recommended by Jeff Casimir: Michael Hartl's Learn Enough Command Line.
