lorem.txt を最初に作ったところに巻き戻す。

$ ls
hello_world.txt lorem.txt       readme.md
$ git checkout ff9444fa9302a63602ab6e84e6c67d2fe0e27844
Note: switching to 'ff9444fa9302a63602ab6e84e6c67d2fe0e27844'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at ff9444f init
