Join?
Hi,

I am trying to exclude certain rows in File 1, based on File 2. i.e. in the example below, File 3 should be the output; i.e. the rows in File 2 are excluded from File 1. Any hints/suggestions would be highly appreciated.

Input File 1:

Code:
a	1	xxx
b	1	wje
c	5	ere
c	2	qqq
d	3	yyy


Input File 2:

Code:
b	1
c	5


Output File 3:

Code:
a	1	xxx
c	2	qqq
d	3	yyy


thanks!
