title: chmod recursive for group but exclude a single file
body: <p>I'm trying to recursively allow a group to read a directory and skip a single file that is contained in within the directory (I am the designated owner of the directory but not for the single file to be skipped for the group).</p>
  <p>To put another way, when I run <code>chmod -R g+r /path/to/directory</code>, no error is thrown and the command does not seem to work due to the single file that is owned by a different user and I want to ignore it (I also tried with <code>-f</code> and got the same result).</p>
  <p>Is there a command to do this? Please advise.</p>
