First of all I want apologize for my English.
I have this problem, I would like to make a phone bill, the first file has Phone number, seconds of the call and call destination, and the second file has the prices for each destination call, and would like to have a third file where it calculate all.

Example:

(Phone number) (seconds of the call) (call destination)

Code:

#!/bin/bash

awk  '
BEGIN {


{while ( getline < "file1.txt" )
            {
        i++       
        f1[i] = $1
          }
      }

{while ( getline < "file2.txt" )
            {    
        x++       
        f2[x] = $1
          }
      }

}


{print [NR], [NR] }' file3.txt

I would appreciate any help.
