% diff dir1 dir2
should do what you need, to compare file existence and contents.
% ls -lrt bittorrent bittorrent2
bittorrent2:
total 82

-rw-r----- 1 smithi smithi 0 Jun 9 2006 not_in_1

Then to just compare (eg) permissions and names, something like:
ls -la dir1 | awk '{print $1,$9}' >/tmp/lsd1
ls -la dir2 | awk '{print $1,$9}' >/tmp/lsd2
diff /tmp/lsd1 /tmp/lsd2
cheers, Ian
