body: <p>How to look for a text through all files inside a folder, where the filenames start with a pattern</p>
  
  <p>for e.g. grep -lr "text-to-find" /path/xyz*</p>
  
  <p>So find "text-to-find" through all files inside a folder where filenames startwith "xyz" inside the folder "path"</p>
  
  <p>I found a few answers online but none of them seem to be working. </p>
