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:

    7  mkdir session_3_practice
    8  touch budget.csv
    9  touch mentors.txt
   10  mkdir notes
   11  cd notes
   12  touch git_notes.txt
   13  touch command_line_notes.txt
   14  cd ..
   15  mkdir practice
   16  cd practice
   17  touch git_practice.txt
   18  mkdir projects
   19  cd projects
   20  touch game.js
   21  ls
   22  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):

ericmeldrum~/practice/projects$ cd ~ ericmeldrum~$ mkdir git_homework ericmeldrum~$ cd git_homework ericmeldrum~/git_homework$ quotes.txt -bash: quotes.txt: command not found ericmeldrum~/git_homework$ touch quotes.txt ericmeldrum~/git_homework$ git init Initialized empty Git repository in /Users/ericmeldrum/git_homework/.git/ ericmeldrum~/git_homework$ git status On branch 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.

Great job, @ericwm76! Looks your formatting in your markdown got a little funky when pasting in your terminal output, but solid work!
