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:

  146  mkdir session_3_practice
  147  cd session_3_practice
  148  touch budget.csv
  149  touch mentors.txt
  150  cd
  151  cd session_3_practice
  152  mkdir notes
  153  cd notes
  154  touch git_notes.txt
  155  touch command_line_notes.txt
  156  .. cd
  157  cd ..
  158  mkdir practice
  159  cd practice

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):

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

Untracked files:

jeannie~/git_homework$ git status

jeannie~/git_homework[master]$ echo 'All you need is love' >> quotes.txt
jeannie~/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")
jeannie~/git_homework[master !]$ git diff quotes.txt
diff --git a/quotes.txt b/quotes.txt
index e69de29..afdfe11 100644

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

 1 file changed, 1 insertion(+)
jeannie~/git_homework[master]$ git status

jeannie~/git_homework[master]$ git log --oneline
7ce6a28 (HEAD -> master) Add favorite quote
fd6ed8f Initial commit
jeannie~/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. I am not feeling super confident in the "Git Practice" section. I beleive I'm not feeling very confident because I am not sure what it is supposed to look like.

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.
