It gives the same result though my direct grep needs one command (cat)
less, so it's a bit less overhead.

Correct. It doesn't really matter, what the result is, though. You could
also return the key again, which is sometimes nice for debugging work.
Postfix doesn't care as long as the lookup is successful it doesn't use
the result in any way (for relay_recipient_maps).

# set domainsnew as result of awk command (one line!)
domainsnew=`awk '!length < 1 && !/#/ && //h {printf ("\"%s\" ",$1)}'
generic`
arraydom=($domainsnew)
echo $domainsnew
# number of elements in array
echo ${#arraydom[*]}
