Changes between Version 6 and Version 7 of Ticket #64142, comment 3

v6	v7
3	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).

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

7	7	On the bright side, unlike the original `ntpstat` program, the newer `ntpstat` supports not only ntp but also chronyc. It is also still being developed.
