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.
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:
108 cd turing
109 mkdir session_3_practice
110 ls
111 cd session_3_practice/
112 mkdir budget.csv
113 ls
114 rm budget.csv
115 rm -rf budget.csv
116 ls
117 touch budget.csv
118 ls
119 touch mentors.txt
120 mkdir notes
121 ls 122 cd notes/
123 TOUCH GIT_NOTES.TXT
124 touch command_line_notes.txt
125 ls
126 cd ..
127 mkdir practice
128 cd practice/
129 touch git_practice.txt
130 mk dir projects
131 mkdir projects
132 ls
133 cd projects/
134 touch game.js
135 ls
Since this is just a practice directory, feel free to remove the parent directory session_3_practice when you're done with this exercise.
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 calledquotes.txt. - Initialize the directory
- Check the git status
- Add your
quotes.txtfile to the staging area - Check the git status
- Create an initial commit
- Check the status
- Add your favorite quote to the
quotes.txtfile - 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):

Watch this video and follow each step to modify your own bash profile. As mentioned in the video, you will need this snippet below:
# get current branch in git repo
function parse_git_branch() {
BRANCH=`git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/'`
if [ ! "${BRANCH}" == "" ]
then
STAT=`parse_git_dirty`
echo "[${BRANCH}${STAT}]"
else
echo ""
fi
}
# get current status of git repo
function parse_git_dirty {
status=`git status 2>&1 | tee`
dirty=`echo -n "${status}" 2> /dev/null | grep "modified:" &> /dev/null; echo "$?"`

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.
