FreeBSD calls them 'flags' rather than 'attributes', and supports searching for them with a '-flags' predicate. Quoting from find(1) on FreeBSD 7.2:
-flags [-|+]flags,notflags
The flags are specified using symbolic names (see chflags(1)).
Those with the "no" prefix (except "nodump") are said to be
notflags. Flags in flags are checked to be set, and flags in
notflags are checked to be not set. Note that this is
different
from -perm, which only allows the user to specify mode bits
that
are set.
If flags are preceded by a dash (``-''), this primary evaluates
to true if at least all of the bits in flags and none of
the bits
in notflags are set in the file's flags bits. If flags are
pre-
ceded by a plus (``+''), this primary evaluates to true if
any of
the bits in flags is set in the file's flags bits, or any
of the
bits in notflags is not set in the file's flags bits.
Otherwise,
this primary evaluates to true if the bits in flags exactly
match
the file's flags bits, and none of the flags bits match
those of
notflags.
