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

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

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

#!/bin/rc

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

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