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:

mkdir session_3_practice
cd session_3_practice
mkdir notes
mkdir practice
touch budget.csv
touch mentors.txt
cd notes
touch git_notes.txt
touch command_line_notes.txt
cd ..
cd practice
touch git_practice.txt
mkdir projects
cd projects
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.

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):

$ mkdir git_homework
$ cd git_homework
$ touch quotes.txt
$ git init
Initialized empty Git repository in /Users/raisaprimerova/git_homework/.git/
$ git add quotes.txt
$ git status
On branch master
No commits yet

Changes to be committed:
(use "git rm —cached ..." to unstage)
new file: quotes.txt

$ git commit -m "Initial commit"
[master (root-commit) d8decbb] Initial commit
1 file changed, 0 insertions(+), 0 deletions(-)
create mode 100644 quotes.txt
$ git status
On branch master
nothing to commit, working tree clean
$ echo "In a time of deceit telling the truth is a revolutionary act." » quotes.txt
$ git status
On branch master

Changes not staged for commit:
(use "git add ..." to update what will be committed)
(use "git checkout — ..." to discard changes in working directory)

modified: quotes.txt

no changes added to commit (use "git add" and/or "git commit -a")
$ git diff quotes.txt
diff —git a/quotes.txt b/quotes.txt
index e69de29..9cb4386 100644
-— a/quotes.txt
+++ b/quotes.txt
@@ -0,0 +1 @@
+In a time of deceit telling the truth is a revolutionary act.
$ git add .
$ git commit -m "Second changes"
[master e782729] Second changes
1 file changed, 1 insertion(+)
$ git status

nothing to commit, working tree clean
$ git log —pretty=oneline
e78272919c1a0a362fbd8daaac054f9daf7e6c23 (HEAD -> master) Second changes
d8decbb2707ed029ad77dacf53a473c628463afc Initial commit

IMPORTANT: Do not remove this git_homework directory. You will be using this directory during Thursday's session.

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.

Hey Raisa - good job on these assignments. Can you take advantage of some of the built in formatting that markdown provides to format the text that you copy/pasted from the terminal in a way that is more readable? Let me know if you have questions!
