Retrieving hash commit-How to retrieve the hash for the current commit in Git?

Question

I would like to retain (for now) the ability to link Git changesets to workitems stored in TFS.

I already wrote a tool (using a hook from Git) in which I can inject workitemidentifiers into the message of a Git changeset.

However, I would also like to store the identifier of the Git commit (the hash) into a custom TFS workitem field. This way I can examine a workitem in TFS and see what Git changesets are associated with the workitem.

How can I easily retrieve the hash from the current commit from Git?

Answer 1

To change arbitrary extended object reference into SHA-1, use the following example commands

git rev-parse HEAD

or

git rev-parse --verify HEAD.
