Re: chown should catch null owner:group

P> Is this just an academic worry, or were you really bitten by it?

Yes. About once a year I do chown -R . file, thinking that -R meant
recursive, oops, I mean "reference"... never expecting it to "work if
it doesn't work", as with most commands, if it doesn't complain, then
it must have worked, and one doesn't look back, until a month later
when one notices some files didn't get written and were now lost due
to a permission problem.
