How to checkout a commit in project history

Change the directory to the Ursa directory in your file system:


Pull the latest commits from main by:

git fetch origin main

💡 A git fetch gathers commits from the target branch that do not exist and stores them in your local repository. It doesn't merge them with your current branch for that use git pull.

git pull origin main

Once you have the latest target branch commits, checkout to any particular commit

git checkout <Commit hash>

A git commit hash is a SHA1 hash of the state of the git repository at the time of the commit. Here's an example:


If you open the Github repository UI, you'll find the commit hash on the right-hand side of the list, check the example here.

You can run the git log command on your local repository directory to find commit hashes.

git log --oneline

Here's an example of how that'd look like:

Let's say that you are interested in checking out the commit feat: Use graphsync to pull data.

git checkout 957ed5c

💡 We can use the first few characters of the commit hash, valid as a short version that refers to 957ed5c92b5a9570cdadc821c571b19698aaf4db.
