Creating Local Repositories with Linear History - Git Recipes - page 89

Problem
The operation of restoring a working directory to a given revision can be performed
with a $ git reset or a $ git checkout command. In Recipe 3-5 you re-
stored old snapshots with a $ git reset command. Now, you want to achieve sim-
ilar results with a $ git checkout command.
Solution
Clone the repository from Recipe 3-4:
$ cd git-recipes
$ git clone 03-04 03-06
$ cd 03-06
and print the history with $ git l . The output will be identical to Listing 3-6 . Save
the output of $ git l for future reference.
Now, restore the working directory to the very first revision, named 7cfb :
$ git checkout 7cfb
This command changes the repository's state into a detached HEAD . You can veri-
fy this with:
$ git status -sb
The output should be:
## HEAD (no branch)
The working directory now contains one file sing-a-song-of-six-
pence.txt and the history printed with $ git l consists of one revision only:
7cfb Sing a song of sixpence
Return it to the normal state with:
