Fun with git

mkdir gittest
cd gittest

edit hello.txt

Hello, World!

exit

cat hello.txt

should be the same

git init
git add .
git commit -m "First commit!"
git branch update
git checkout update
cat hello.txt

should be the same
edit hello.txt

Hello, world!
Don't leave me!

save, exit

git add .
git commit -m "Update hello.txt 1"

Hmm. I don't like that. I've already committed!

git checkout HEAD~1 -- hello.txt

It's back!
edit hello.txt

Hello, world!
I love you!

save and exit

git commit -m "Love never dies"
git checkout master
cat hello.txt

It's gone?

git checkout update
cat hello.txt

It's back!

git log 

I need that entry n commits ago, but just for hello.txt

git checkout HEAD~n -- hello.txt
