You mean UFS2? :)
% mount
/dev/ad1s3a on / (ufs, local)
devfs on /dev (devfs, local)
/dev/ad1s2d on /home (ufs, local, soft-updates)
/dev/ad1s3d on /tmp (ufs, local, soft-updates)
procfs on /proc (procfs, local)
(The test was under /home.)
Thanks for the info. In any case, cat do misbehave when both directories and
files are passed as parameters, as it doesn't cat anything else after the
directory:
% cat -n Makefile Makefile . Makefile Makefile
1 # @(#)Makefile 8.1 (Berkeley) 5/31/93
2 # $FreeBSD: src/bin/cat/Makefile,v 1.7 2001/12/04 01:57:37 obrien Exp
