What is a Git Commit?

Last updated on February 7, 2021 by Sal Ferrarello

A Git commit, represented by a single building block in my Git mental model, is a frozen moment in time for your project (sometimes referred to as a snapshot). Along with this snapshot Git stores metadata about the commit (e.g. the author of the commit). Each commit has a unique identifier called the commit hash (a.k.a. SHA), a 40 character long alphanumeric string that is often abbreviated to just the first seven characters (e.g. “2b3a38b”).
