#125 Exit code should be nonzero on permission denied

[Ian Chard]

Currently 'quota -u username' will exit with a zero status code even if permission is denied.

$ quota -u root
quota: root (uid 0): Permission denied
$ echo $?
0

It should exit nonzero as this is a failure. I'll try to submit a patch shortly.

Thanks for report.
