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:

paste your commands here
22  mkdir session_3_practice
   23  ls
   24  pwd session_3_practice
   25  ls
   26  touch budget.csv
   27  touch mentors.txt
   28  ls
   29  cd ..
   30  rm mentors.txt
   31  cd ..
   32  rm budget.csv
   33  cd .. 
   34  ls
   35  home
   36  ls
   37  rm mentors.txt
   38  ls
   39  rm budget.csv
   40  ls
   41  pwd
   42  session_3_practice
   43  ls
   44  cd session_3_practice/
   45  touch budget.csv
   46  touch mentors.txt
   47  cd ..
   48  cd
   49  cd session_3_practice/
   50  ls
   51  cd ..
   52  cd session_3_practice
   53  mkdir notes
   54  cd notes
   55  touch git_notes.txt
   56  command_line_notes.txt
   57  touch command_line_notes.txt
   58  cd ..
   59  mkdir practice
   60  cd practice
   61  touch git_practice.txt
   62  mkdir projects
   63  cd projects
   64  touch game.js
   65  ls
   66  cd .. 
   67  cd ../..
   68  ls
   69  cd session_3_practice/
   70  ls
   71  cd practice
   72  ls
   73  touch git_practice.txt
   74  cd ..
   75  ls
   76  cd practice
   77  ls
   78  cd projects
   79  ls
   80  history
zoeketchamharvey~/session_3_practice/practice/projects$ 

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 (yes, oneline, not a spelling error) format

Copy and paste all of the terminal text from this process below (not just the history):

3. Classes, Attributes, and Methods

Look at the template below for a CardboardBox class. Fill in missing blanks with additional attributes and methods.

Class: CardboardBox

Attributes:

• width (integer)
• depth (integer)
• height (integer)
• color (style?)

Methods:

• break_down
• stack
• fill_with_items
• recycle

4. Questions/Comments/Confusions

If you have any questions, comments, or confusions that you would an instructor to address, list them below:

1. In the attributes section of part #3, i understand why the height/width/depth are integers, but I wasn't sure what would belong with the color attribute.

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.
