since you already use awk, it's probably best to use printf instead of print.
And awk can also search for the right line. If I understand the
format of the output of DiG correctly, it would be
changequote([,])
define([MY_IP_ADDR],
esyscmd([dig @my.ns.domain.com machine.domain.com |
awk 'index($ 0, "machine.domain.com") == 1 {
printf("%s", $ 5) }']))
Portability notes:
This will work with any reasonable awk.
Warning: Solaris' /bin/awk is not reasonable, so this might fail.
In that case, you might try try /bin/nawk, it's better.
Most instalations of Solaris', but not all, have a reasonable awk
under /usr/xpg4/bin/awk.
Other unices have reasonable awk under /bin/awk, I think.
Enjoy,
Stepan
