Well, the original point was that I don't really see the point of the=20
program at all. Even if it were part of the main distrobution, it's=20
still such a trivial program that it seems fitting that it be provided=20
as a script, as are many other such programs.

As for the speed, I just can't imagine it being an issue in practice,=20
but I also can't really imagine using the program at all, rather than=20
just grepping /proc. All in all, it doesn't matter much to me, it just=20
seems much simpler to just write it in rc.

The other problems you mentioned seem trivial. Redirecting greps stderr=20
to /dev/null solves the second 2. There are a number of simple ways to=20
solve the first.

#!/bin/rc

if(~ $#* 0)
	f =3D /proc/*/fd
if not
	f =3D /proc/^$*^/fd
f =3D `{ls $f | sort -t/ -n +2}

grep '.?' $f >[2]/dev/null | sed 's,^/proc/([0-9]+)/fd:,\1	,'

--=20
