find common lines using just one column to compare and result with all columns
Hi.
If we have this file
A B C
7 8 9
1 2 10
and this other file
A C D F
7 9 2 3
9 2 3 4
The result i´m looking for is intersection with A B C D F
so the answer here will be
7 8 9 2 3
So how do we do a intersection using to compare just the column 1 .
I think what I want is very similiar to this topic, but didn´t work for me

I´m lost for my next step.
I´m using solaris 10
Thanks very much.
