If parsing ps output *freezed*, I think you did something wrong. Some other utilities like zap (from ports) do exactly that. Then, there's the possibility to use the direct sysctl interface, using CTL_KERN as the first level name and the KERN_PROC* names on the second level, see the manual page sysctl(3). That's the way how ps(1) and top(1) do it if I'm right. Kind regards, Hannah.
