Pete, thank you for asking.

Yes, I can write. It is not the problem, since the generated code from
the awk file is  OK.

No, this is the out from

echo ngctl msg ${NODEPATH} setprogram { thisHook=\"${INHOOK}\"
ifMatch=\"${MATCHHOOK}\" ifNotMatch=\"${NOTMATCHHOOK}\" ${BPFPROG} } }

I added the echo command to see how it is getting executed. So I have
the echo and on the next line the command itself. Note that this was
just copied/pasted from the man page, with the exception of the
PATTERN.
