Matching 2 files

Hi,

I am able to modify files (one file) but I have a hard time working with multiple files simultaneously.

So I have two files. Basically I want to match two files based on certain columns. Both files are tab-seperated.

File1 looks something like this:

Code:

num1  89  george
num4  78  bob

File 2 is a much larger file and looks somethign liek this:

Code:

num1  3    lion
num1  13  tiger
num1  84  bear
num4  3    house
num4  19  dog
num4  77  mouse

So what I want to do is match column 1 from Files1 and 2. I also want to substract column 2 from both files. So if they are a match, I want to print (into a seperate file) the row with the smallest difference for column 2.

So for my example above, the output file would look like this

num1 5 george bear
num4 1 bob mouse

thanks
