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:

   14  cd
   15  mkdir session_3_practice
   16  cd session_3_practice
   17  touch budget.csv
   18  touch mentors.txt
   19  ls
   20  mkdir notes
   21  cd notes
   22  touch git_notes.txt
   23  touch command_line_notes.txt
   24  ls
   25  mkdir practice
   26  cd practice
   27  touch git_practice.txt
   28  ls
   29  mkdir projects
   30  cd projects
   31  touch game.js
   32  ls
   33  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):

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

Untracked files:

	quotes.txt

sam~/git_homework$ git add quotes.txt
sam~/git_homework$ git status

Changes to be committed:

	new file:   quotes.txt

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

sam~/git_homework[master]$ echo "He who fears he will suffer, already suffers becasue he fears" >> quotes.txt
sam~/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")
sam~/git_homework[master !]$ git diff quotes.txt
diff --git a/quotes.txt b/quotes.txt

sam~/git_homework[master]$ git log --oneline

1a2cf0c Initial commit
sam~/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:

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.
