need help with a simple awk statement

[g2345c]

hi, I want to add a line to file new.log if /var/log/new.log is not presented in the file.
But it add:
$A_STRING /var/log/new.log
instaed of
local0.debug /var/log/new.log


#!/bin/sh
A_STRING=local0.debug

awk '/\/var\/log\/new.log/{++n}{print}END{if(!n)print "\n$A_STRING /var/log/new.log"}' syslog.conf > tmp.conf

thanks

Have you tried this ?
awk '/\/var\/log\/new.log/{++n}{print}END{if(!n)print "\n'$A_STRING' /var/log/new.log"}' syslog.conf > tmp.conf
Or this ?
fgrep -q "$A_STRING" syslog.conf || echo "\n$A_STRING /var/log/new.log" >> syslog.conf

Hope This Helps, PH.
