Thanks guys, but I have a problem using this in awk code, is there a way to pass this in a print statement in awk?

For example
awk '{
if ($1 ~ "^[(0-9]+\.[0-9]+\.[0-9]+\.[0-9)]+$" )
{print `sed "s/[()]//g"`'${1}'}

The above code does not work. Basically the logic checks to see if the first field in a txt file is an ip then print out the ip stripping the parantheses.

echo '(' | nawk 'match($1, "^[(0-9]+\.[0-9]+\.[0-9]+\.[0-9)]+$") {print substr($1,RSTART+1,RLENGTH-2)}'
