look for line from FILE1 at FILE2
Hi guys!

I'm trying to write something to find each line of file1 into file2, if line is found return YES, if not found return NO. The result can be written to a new file.

Can you please help me out?

FILE1 INPUT:

WATER
CAR
SNAKE
(in reality this file has about 600 lines each with a different word)

FILE2 INPUT:

A
B
C
ABC.WATER.DEF
D
ABC.CAR.DEF

If I ran this script on above files it would return something similar to this in new file:

WATER YES
CAR. YES
SNAKE NO

Thanks a lot!
