----- Guess I got a bit carried away. On the above list with --one-file-system, only 'rm' is missing -x as a shorthand for it. I don't know that either BSD or Solaris have a one-file-system option, so it seems unlikely they would have a -x. secure rm does have -x, which has the same meaning. You can create any arbitrary set of conditions that fulfill your need for acceptance or denial. tar also uses -x and find uses -xdev. Clearly there are 4 other utils that use -x to mean stay on this file-system with -xdev being a weak fifth since find doesn't have many (if any) "--long" options.
