Thanks for the info, but the devices encumbered with ioctls are the tricky ones and even if they can be sorted out I'm sure there are some other traps out there. Too bad there are no RFS gurus lurking here to offer their wisdom on remoting devices. I'm no RFS guru, thank deity, but I did

One thing I suspect people may be forgetting in the race to emulate YA feechure of YA UNIX variant is that one of the reasons for DTrace's complexities (hierarchical namespace, in-kernel interpreter) is the complexity of the Solaris kernel. When they're trying to work out how a thread in a

You can do it, definitely. Caveat: I'm in bed with a virus and the brain's on impulse power so these are untested and may be highly suboptimal. Is the input guaranteed to have 2 words on each line? What are your definitions of words and blanks? I know from your snippet that there's no leading
