    Session 2 Practice Tasks

The assignments listed here should take you approximately 55 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:
 107  mkdir session_3_practice
  108  cd session_3_practice
  109  touch budget.csv
  110  touch mentors.txt
  111  mkdir notes
  112  cd notes
  113  touch git_notes.txt
  114  touch command_line_notes.txt
  115  cd ..
  116  mkdir practice
  117  cd practice
  118  touch git_practice.txt
  119  mkdir projects
  120  cd projects
  121  touch game.js

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.

Create a directory called git_homework. Inside of there, create a file called quotes.txt.
Initialize the directory
Check the git status
Add your quotes.txt file to the staging area
Check the git status
Create an initial commit
Check the status
Add your favorite quote to the quotes.txt file
Check the status
Check the diff
Add the changes to the staging area
Commit the new changes
Check the status
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 (15 min)

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 (string)

Methods:

break_down
stack
fill
empty

4. Modify your Zsh Prompt (10 min)


Make sure that your shell is set to zsh by running the following command: $ chsh -s /bin/zsh. Remember to omit the $! Note that macOS Catalina and later operating systems already use zsh as the default shell.


 Watch this video and follow each step to modify your own zshrc configuration file. As mentioned in the video, you will need this snippet below:


# Load version control information
autoload -Uz vcs_info
precmd() { vcs_info }

# Format the vcs_info_msg_0_ variable
zstyle ':vcs_info:git:*' formats '%b'

# Determine if current working directory is a git repository
git_branch_color() {
  if current_git_status=$(git status 2> /dev/null); then
    parse_git_dirty
  else
    echo ""
  fi
}

# Change branch color if working tree is clean
parse_git_dirty() {
  if current_git_status=$(git status | grep 'Changes to be committed:\|Untracked files:\|modified:|deleted:' 2> /dev/null); then
    echo "%F{red}"
  else
    echo "%F{green}"
  fi
}

# Set up the prompt (with git branch name)
setopt PROMPT_SUBST
PROMPT='%F{white}%d $(git_branch_color)${vcs_info_msg_0_} %f$'

5. Questions/Comments/Confusions

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

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.


This course is how I personally learned command line. If time permits, I highly recommend reading and practicing.


Also recommended by Jeff Casimir: Michael Hartl's Learn Enough Command Line.
