Suppose I have a directory with a HUGE number of filenames, all of which
happen to look like integers:

~/nntp/1
~/nntp/2
~/nntp/3
..
..
..
~/nntp/59874
~/nntp/59875
~/nntp/59876

Now, in a PHP script, what's the most efficient way to find the "largest"
filename, where "largest" means in the sense of an integer, not a string?

I could probably force the filenames to be 0-padded if that would make a
significant difference.

Is there some nifty shell command I should just "exec"?...

I don't really care which shell, but I'm a bash user generally.

Obviously I could loop through all the filenames, so I'm looking for
something faster than that. :-)
