bind/script question

[Kevin Darcy]

Traditionally:

if kill -0 `cat /var/run/named.pid`; then echo up; else echo down;fi

(At least, that works in Bourne shell. Obviously you'd replace one or both
echo's with whatever you needed. Note that you have to run this with sufficient
permissions -- superuser or whatever ID you run named as -- otherwise you'll
have to do more work to parse the result).

You could probably replace that "kill" command with an "ndc status" if you
wish.
