try this script:
for i in 'find required files';
do
awk '{if($1=="set" && $2=="abc" && $3=="1") {print $1,$2,"0"} else {print
$0}}' $i
done;
i haven't tried it - I am not that good at shell scripting
Pipes are what i like - this loop is from my mentor.
If i get a piped workout - will let you know ;)
