What is a commit in Git?

A commit in Git is the state of a file and directory at some point in time. It is identified by a 40-digit commit ID.

#Commit ID

Once you know the commit ID, you can revert the files and directories back to that state.

Git has information about the differences between files and directories between individual commits, and by stacking them from the first commit, it restores the state of the files and directories at some point in time.

Does the commit ID conflict?

Since the commit ID is the value of the SHA1 hash function, it is possible to collide, but since it is an astronomically small probability, it is probably okay for practical use. Even if it hits, you should be able to avoid it by making a slight change to the source code, such as "adding a blank".
