This is available under Mac OS X too.

The following flags to the command line might be helpful:

-q Quiet mode, doesn't update the screen 10 times a second
   while scanning, reduces network bandwidth used

-x Don't cross filesystem borders (don't descend into a
   directory which is a mounted disk)
