road-not-taken.txt
==========================================================================
I Took All the Roads, by Robert Forks

Two roads went exactly the same way
And I was happy to travel them both
And be one traveler, I figured it out quick
blah blah blah
blah blah blah blah

blah blah blah blah
Both had terrible claims
Because it was smooth and boring
blah blah blah blah
This poem is terrible, Rob.

blah blah blah blah
In leaves no step had trodden blah
Oh, blah blah blah BLAAAAHHH
WEEEEEEEE!! This road is awesome.
I'm definitely coming back here!

Hahahahahahahhaha
Two roads diverged in a hahahahaha
HAHAHAHAHAHAHHAHAHAHAH! Gotcha.
==========================================================================

1.The file road-not-taken.txt doesn’t look right at all! Perhaps a rival poet snuck in and changed it while you were getting coffee. Good thing you’ve been committing often.
Checkout the HEAD version of road-not-taken.txt to discard changes made to the working directory.

$ git checkout HEAD road-not-taken.txt  

2.Now, finish the poem by adding a line. Here's a suggestion:
==========================================================================

And that has made all the difference.

==========================================================================
Then  Save.

3.Take a look at oven-bird.txt to see if it has also been tampered with.
Indeed it has! We’ll want to discard changes in the working directory again.
There’s a commonly used shortcut for this command:

$ git checkout -- filename

It does the same exact thing that git checkout HEAD filename does. Try it with oven-bird.txt.

$ git checkout -- oven-bird.txt

4.Now, finish "Oven Bird" by adding a line. Here's a suggestion:
==========================================================================

Is what to make of a diminished thing.

==========================================================================
Then  Save.

5.Click on fire-and-ice.txt.
This file has not been altered, but just to be sure, check the diff for this file.
Then, add these last two lines to the poem:
==========================================================================

Is also okay
And would suffice.

==========================================================================

$ git diff  

6.Now that you’ve restored and completed road-not-taken.txt and oven-bird.txt and added a line to fire-and-ice.txt, add all three of the files to the staging area with a single command.

$ git add road-not-taken.txt oven-bird.txt fire-and-ice.txt

7.fire-and-ice.txt could be better. Before you commit, remove this file from the staging area. 

$ git reset HEAD fire-and-ice.txt 

8.Now that you've removed fire-and-ice.txt, make a commit.

$ git commit -m "Ying Yu Commit"

9.You get the crazy idea to change your poems in a big way.

Make some drastic changes to each of the three poems. Remember to click Save after each file change.

10.Now add all three files to the staging area.

$ git add road-not-taken.txt oven-bird.txt fire-and-ice.txt 

11.Make a commit

$ git commit -m "Becky 2nd Commit" 

12.A little later you take a look at the current state of your poems and regret your last commit.

Reset your Git project to the commit before you made those drastic changes.

$ git log

$ git reset d7722af 

13.There’s a problem: you reset HEAD to a previous commit, but the changes you want to get rid of are still in the working directory.

What Git backtracking command that you already know can discard changes to the working directory, restoring the files to the way they look in the HEAD commit?

$ git checkout HEAD road-not-taken.txt oven-bird.txt fire-and-ice.txt
