extract regexp result from string and write it to a variable

Here is my command :

grep -E '\*[[:space:]]+FIN[[:space:]]+([^)]+?)') myfile

It outputs :

• FIN (SUCCESS)

And I would like it outputs only :

SUCCESS

How can I tell grep to do it ?

Answer 1

You can pipe the output of your grep command to the awk command.

grep -E '*[[:space:]]+FIN[[:space:]]+([^)]+?)') myfile | awk '{print $2}'

I am not sure how to do that with grep alone, as it is not really tailored to that exact use case. Since you are on a platform where grep is, use pipes to your advantage when you can have one command solve part of the problem, and another command the other part.
