I get a different error on a 13.0-RELEASE machine I converted from 12 to
current about a year ago (bash and sh):
$ tail /COPYRIGHT <&-
tail: can't limit stdio rights: Bad file descriptor
works with sudo:
$ sudo tail /COPYRIGHT <&-
* California, Berkeley and its contributors."
etc etc...
but not as root, with a different error in sh:
# tail /COPYRIGHT <&-
Missing name for redirect.
as root in bash:
# tail /COPYRIGHT <&-
tail: can't limit stdio rights: Bad file descriptor
works as both user and root in ksh
