title: How to collect a name list from a sub-folder in git
body: <p>use case is, the git repository is a <a href="https://en.wikipedia.org/wiki/Monorepo" rel="nofollow noreferrer">monorepo</a>, I want to know who worked on a sub-project in history and get the name list.</p>
  <p>For example, I'd like to know who involved and merged the codes to this sub-folder <code>PackerBuildV1</code>.</p>
  <p>Only need target on master/main branch.</p>
  <p><a href="https://github.com/microsoft/azure-pipelines-tasks/tree/master/Tasks/PackerBuildV1" rel="nofollow noreferrer">https://github.com/microsoft/azure-pipelines-tasks/tree/master/Tasks/PackerBuildV1</a></p>
  <p>any hints for me?</p>
