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:

  101  pwd
  102  ls
  103  cd desktop
  104  ls
  105  mkdir session_3_practice
  106  ls
  107  cd session_3_practice/
  108  ls
  109  touch budget.csv
  110  ls
  111  touch mentors.txt
  112  ls
  113  mkdir notes
  114  cd notes
  115  ls
  116  touch git_notes.txt
  117  ls
  118  touch command_line_notes.txt
  119  ls
  120  cd ..
  121  ls
  122  mkdir practice
  123  ls
  124  cd practice
  125  ls
  126  touch git_practice.txt
  127  ls
  128  mkdir projects
  129  ls
  130  cd projects
  131  ls
  132  touch game.js
  133  ls
  134  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):

Desktop		Downloads	Library		Music		Public		sonnets.txt
q~ cd desktop

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.
