Check users for ~/.my.cnf files that do not work and disable them. By default it only has output when a bad ~/.my.cnf is detected.

  $0 --dryrun     - do not disable an invalid ~/.my.cnf just report the problem
  $0 --user=USERA [--user=USERB} - specify a user (or users by using more than one --user flag) to check instead of checking all users
  $0 --perm-only - Do not test the connectivity, only do the mode and ownership check.
