title: Is there any automatic way of adding directives in all my existing files of my angular project?
body: <p>Suppose I have to add a <code>directive</code> called <code>bidi</code> in all my <code>matInput</code> fields .And I have approx 1000 input fields in 250 files in my project.
  Is there any way to automate this process instead of manually doing it?
  Thanks.</p>
