Extracting data between two characters
From the command line how would I extract data in file that was contained between parenthesis "()"? Awk or Grep?

Thanks in advance

The answer lies somewhere here.

echo "abc(opp)aop" | sed -n 's/(.*)//p'

This will give output abcaop
and I think the request is other way around content within brackets

Code:
echo "abc(opp)aop" | sed "s/.*(\(.*\)).*/\1/

With awk:
Code:
echo "abc(opp)aop" | awk -F"[()]" '{print $2}'

Code:
echo "abc(opp)aop" | awk -F"(" '{print $2}' | awk -F")" '{print $1}'

or
Code:
echo "abc(opp)aop" |cut -d"(" -f2 | cut -d")" -f1

These solutions should do the job too, but not at the most efficient way.
