Texas A&M University

FreeBSD hermit.bcs.nostrum.com 3.2-STABLE FreeBSD 3.2-STABLE #0: Wed Jul 28 15:40:30 CDT 1999 root@hermit.bcs.nostrum.com:/opt/src/system/src/sys/compile/Hermit i386
>Description:
I am familiar with having a '-n' option to /bin/ls on other platforms (i.e.
Solaris/Linux/IRIX/etc) to print uid/gid information numerically in long
(-l) listings rather than performing username/groupname lookups. I was
unable to find any similar option to /bin/ls or similar programs. (Unless
I just completely overlooked it).
>How-To-Repeat:
No similar option found on FreeBSD, other OSs output similar to:
% ls -ldn
drwxr-x--x 9 1179 100 4096 Jul 29 00:53 .
>Fix:
Determine if my patch is acceptable, as given, or in concept; and apply in
