Awk one-liner?
Hello,
I have two files...

File #1
Code:
1 3
2 5

File #2
Code:
3 5 3
1 3 7
9 1 5
2 5 8
3 3 1

I need to extract all lines from File #2 where the first two columns match each line of File #1. So in the example, the output would be:

Code:
1 3 7
2 5 8

Is there a quick one-liner that would accomplish this?

Thanks so much!
