Weapons

log show checkout
Workspace

~/git-quest/quest3/git-quest3

If you’re already confident with log and show and checkout you can still read the Short answer to understand this quest intent.

 Remember you don’t need to edit the project files. If you’re in trouble, reset this quest with git-quest init 3.

Before you start

Run git-quest init 3 to setup your environment for this quest. To ensure you can begin your quest in good conditions, go to the quest repository: ~/git-quest/quest3/git-quest3.

And run the two following commands to make sure both project and repository are in the right state.

Repository status
$ git status
On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean
 Didn’t get same results ? Reset the quest by running git-quest init 3 again

From here, if you’re familiar with git, go ahead and try to complete your quest on your own. Besides, for apprentices, I’ld recommand to follow the step by step solution first. Then, reset the quest and try to complete it without any help.

Check your result

Once you think you finished the quest, run the following command and check the output.

$ git log -1
commit 7e56812e40b27d52dc42fdb42b2a10ad69a4b2d2 (HEAD) (1) (2)
Author: john.doe <john.doe@>
Date:   Fri Jan 4 09:47:22 2019 +0100

    Translate message in ASCII art

  1. Commit SHA1: 7caf5b029e53ed3eafeeb25db7e61b33d8e243ec

  2. Commit location: detached HEAD (HEAD)

You miss something if you get an error or something different.

If you completed this quest on your own, it’s still relevant for you to read the Short answer. You can compare your solution with mine.
