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:

  196  mkdir turing
  197  cd turing
  198  mkdir mod_0
  199  mkdir prework
  200  ls
  201  touch budget.csv
  202  touch mentors.txt
  203  ls
  204  cd mod_0
  205  touch git_notes.txt
  206  touch oop_notes.txt
  207  ls
  208  cd turing
  209  cd prework
  210  touch assignment_list.txt
  211  mkdir projects
  212  ls
  213  cd projects
  214  touch game.js
  215  history

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 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):

kylemac~ mkdir git_homework
kylemac~ cd git_homework
kylemac~/git_homework touch quotes.txt
kylemac~/git_homework git init
Initialized empty Git repository in /Users/kylemac/git_homework/.git/
kylemac~/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)
kylemac~/git_homework git add quotes.txt
kylemac~/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

kylemac~/git_homework git commit -m "Initial Commit"

kylemac~/git_homework[master] echo "To Be Or Not To Be" >> quotes.txt
kylemac~/git_homework[master !] cat quotes.txt

kylemac~/git_homework[master !] git diff quotes.txt
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.

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.
