Another month later, you're woking on an essay about tardigrades!
|
|
|
|
But this time, a friend has borrowed you a time machine!
|
|
|
|
It's called "Git", and it's very shiny.
|
|
|
|
[setup]
|
|
|
|
rm -rf .git
|
|
|
|
echo "~ Why tardigrades are cool ~
|
|
|
|
- They can survive in space.
|
|
- They are resistant to extreme heat and cold." > essay.txt
|

# Initialize the time machine!
|
|
test -d .git
|
|
|
|
# Make a snapshot of your essay (a "commit")
|
|
test -d .git && git rev-parse HEAD
|
|
|
|
# Add another line to the essay.
|
|
test "$(cat essay.txt | wc -l)" -ge 5
|
|
|
|
# And make a second commit!
|
|
git rev-parse HEAD^ && test "$(git show HEAD:essay.txt | wc -l)" -ge 5
|
|
|

[congrats]

Nice! You can now travel between those two snapshots using `git checkout` - try it, and look at the essay in each commit!
