that would work on *nix, but not windows.
Since I am developing and deploying on *nix, shell commands are fine
with me.

if you want a cross-platform solution (not that i use windows :))
or you dont want to use exec() or related functions look to the stream
functions. they support buffered reading, so theorectically a
script could
read portions of a file and count lines as it read through the
portions.
Sounds a little painful. I'll look into it though.
