title: terminal unix command find problem with setting up modes
body: <p>I have trouble constructing a single find line to do the following:
  find all files in the current dir and sub-dir with name ending with ~. or star and end with '#'.I think I have made a fundamental mistake but not so sure after 2 hours of thinking.</p>
  <p>This is what I came up with and it does not seem to work:
  find -name '[#]<em>' -a -name '</em>[~#]'</p>
  <p>macOSX terminal</p>
