title: Find all files matching a given pattern AND excluding a given pattern?
body: <p>I want to find all files in a directory that match a given pattern say A and don't match a given pattern say B</p>
  
  <p>What I've tried:
  Doing "ls -I B" gives me all files which match the pattern B. But I'm not getting any leads on how to do what I want to.</p>
