Based on How can I undo the last commit in Git? .
Is there a way to return a Git repository to a specific commit?
For example:
Is there a way to go back to "commit c"?
You should only do git checkout commitC where commitC is the hash of that commit.
Example:
You look in the git log for the commit you want to return to:
git log
You'll have something like this:
commit eb9b03c2e22305c965b610aa84a7d316e5cb208d

commit1
You can see more information about git log here.
Then you do this:
git checkout eb9b03c
For more information on git checkout you can see here.
Then your HEAD will be pointing to the commit3 , being the result you need.
Just execute the following command (replace <hash> ):
$ git checkout <hash>
In order to make the jump from one confirmation (commit) to another, you must know the number (hash) by which it was registered. Taking into account that the official book of Git in Spanish, section 2.3 Fundamentals of Git - Viewing the confirmation history , tells us:
After having made several confirmations, or if you have cloned a repository that already had a history of confirmations, you probably want to look back to see what modifications have been made. The most basic and powerful tool to do this is the
git logcommand.
When you execute the git log command on your project, you will have something like this:
$ git log

Primera confirmación
The hash (or confirmation number) will be the alphanumeric set that is followed by the word commit . You will copy this hash to use it with the command git checkout <hash> that will take care of moving the pointer HEAD of your project to the indicated confirmation. Visual example (taking into account that you are the project is the branch master ):
In this way we can perceive that although your pointer now points to a previous capture, your subsequent changes to it still exist.
You can get more official information and in Spanish related to this topic in the following link: 6.1 Git tools - Selection of confirmations of specific changes
Short SHA : Simply by giving it the first characters of the SHA-1 code, Git is smart enough to figure out what the desired commit (commit) is. It is necessary to type at least 4 characters and these must be unambiguous --ie, there must be a single object in the repository whose code starts with that initial piece of SHA -.
