Did you know that creating parallel timelines is perfectly legal and safe? It's true!
|
|
|
|
Can you find out when things went wrong in this zoo, and create commits that tell a better story?
|

[setup]
|
|
|
|
mkdir cage
|
|
echo "Looks very hungry." > cage/lion
|
|
|
|
echo "A small child.
|
|
It really loves cats!" > child
|
|
git add .
|
|
git commit -m "The beginning"
|
|
|
|
echo "It's holding a lollipop." >> child
|
|
git commit -am "The child buys something"
|
|
|
|
mv child cage
|
|
git add .
|
|
git commit -m "The child is curious"
|
|
|
|
git rm cage/child
|
|
echo "Looks happy. :)" > cage/lion
|
|
git add .
|
|
git commit -m "Oh no"
|
|
|
|
echo "It's sleeping." > cage/lion
|
|
git add .
|
|
git commit -m "Nap time!"
|
|
|
|
git checkout --detach
|
|
git branch -d main
|
|
|
|
[win]
|
|
|
|
# Is the child still there, and is the lion not hungry?
|
|
{ git ls-tree --name-only -r HEAD | grep child; } && { git show HEAD:cage/lion | grep -v "very hungry"; }
|
|

Whew, good job! This seems like a *much* better outcome.
|
|
|
|
Feel free to add more parallel timelines, or make them longer.

If you're ready, our next mission is already waiting...
