title: How to add a file to every git repository in a Bitbucket project
body: <p>There is a Bitbucket project with roughly 40 repositories. I would like to add a Jenkins file with lint checking:</p>
  
  <pre><code>staticTests {
      lintTargets = ["*.yml", "roles"] }
  </code></pre>
  
  <p>to each repository, because cloning each repo, adding the file, then committing and pushing to each repo is a tedious and time consuming task. </p>
  
  <p>I did some searching to check if there is an accepted way to do this automatically, however I could not come up with anything. </p>
  
  <p><strong>EDIT</strong>: I believe this question is different to <a href="https://stackoverflow.com/questions/849308">pull/push from multiple remote locations</a> due to involving different repositories rather than different remote locations for the same repository.</p>
  
  <p>tl;dr: How to add a file to multiple different git repositories at once?</p>
