title: How to see a merge history?
body: <p>I'm using git but I'm not an expert with it.</p>
  
  <p>I inherited a legacy project and it follows git flow (and I like it): each new feature in a <code>feature/name</code> branch. But when new features were merged into <code>develop</code> main branch they were not erased from <code>origin</code>. So that now in origin I see a lot of branches and I don't know which one are old one or which are working-progress.</p>
  
  <p>Is there a way to have an history of the merges done between feature branches and the develop?</p>
  
  <p>EDIT: I'm on a linux machine</p>
