adventures     com|hum
adversity    com|hum|hum

and File B looks like this:

Code:

adventure
adventures
adversary
Adverse
adversity

I want to print those lines in File A in which the value in Column 1 also appears in File B.

Thus, the desired output would be to print those lines from File A:

Code:

adventures     com|hum
adversity    com|hum|hum

I know there is a grep that does the opposite of that:

Code:

grep -F -x -v -f fileB fileA

But, is there a way to modify it so that I can reach my desired output?
Thank you
