And what is hz, hz = ? bash-2.02$ man delay No manual entry for delay Can't answer the first part, but I imagine that hz means Hertz, properly abbreviated as Hz. 1 Hz is 1 cycle per second or one second per cycle. Metric prefixes apply, therefore 1 kHz = 1000 cycles per second (0.001 seconds or 1 ms per cycle), and so on. -- Chris Hill chris@monochrome.org [1] Bus error netscape To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
