Ticket #64142, comment 3
v7 v8 1 1 P.S. I just discovered another program with the same name `ntpstat`. Unlike the original `ntpstat` which was written in C and did not rely on `ntpq`, the newer `ntpstat` is a shell script which prints the ntpd or chronyd synchronisation status, using the `ntpq` or `chronyc` program. See See https://github.com/mlichvar/ntpstat 2 2 3 It emulates the original `ntpstat` program written in C by G. Richard Keech, which implemented a subset of the mode 6 ntp message protocol supported by `ntpd`. But please note that it has an additional dependency that the original `ntpstat` did not have. It requires `gawk` (at least on older Macs where `awk` is pretty limited. I had to patch the original script replacing `awk` with `gawk` everywhere to make the newer `ntpstat` work on my older Macs).3 It emulates the original `ntpstat` program written in C by G.

It would have been better if the newer `ntpstat` used NTP mode 6 control messagesprotocol directly to `ntpd` (e.g.via C functions), like the original `ntpstat` program did, instead of using `ntpq` in "raw" mode . (see https://github.com/mlichvar/ntpstat/pull/4). But that is a lot more work and the ntp control message protocol is obscure.5 Another downside to the newer `ntpstat` program -- it is NOT fully POSIX shell (sh) compatible.

It is also still being developed.
