#66 fuser return status determined by last name only

[Anonymous]

The fuser command only looks at the last name listed on the command line to determine its matching (or killing) return status. This is counterintuitive (to me), because e.g. grep returns success if a match is found in any listed file. (Or killall which returns error if any kill failed, but its name says all, so that seems logical.)

I'm attaching a patch that makes fuser return with success if any match was found, or any process was killed. It may seem strange that the exit status can still be success if it failed to kill some process, but that's no different than before, and I expect this to be the most useful behaviour.

This can be seen where:
sleep 100 &
fuser -k /bin/sleep /bin/false
returns 1

but
fuser -k /bin/false /bin/sleep
returns 0

The correct response is to always return 0 (which is what the fuser does without the k option).

I think there is a simpler solution to this problem.

This bug was fixed in [7c5cb8] a different way, but it gives the correct return value.
