title: How do I find the next commit in Git? (child/children of ref)
body: <p><code>ref^</code> refers to the commit before <code>ref</code>. What about getting the commit <em>after</em> <code>ref</code>?</p>
  <p>For example, if I <code>git checkout 12345</code>, how do I check out the next commit?</p>
  <p>Yes, Git's a <a href="https://en.wikipedia.org/wiki/Directed_acyclic_graph" rel="noreferrer">DAG</a> node pointer struct tree whatever.  <strong>How do I find the commit after this one?</strong></p>
