Subtracting numbers in two different txt files

Arjani

I have two .txt files with a bunch of numbers in them, below each other, like this:

File 1:

3
4
5

File 2:

1
2
1


Now I want to subtract the numbers in file 2 from the numbers in file 1 and get the results in a new .txt file:

File 3:

2
2
4

Very simple. I was going to do it in Excel, but I don't have that right now. Does anyone know another easy way?

Use OpenOffice then. Or write Python script. Or post your problem giving enough information about OS and tools available to get a meaningful answer.

If you've got Windows, try VBScript. Read the 2 files into an array, add the elements of the arrays and write the results back out. Here's a link showing how to read and write files: http://easyprograming.com/index.php/...e-in-vb-script

You could download Open or Libre Office, or sign up for a GMail account and use the spreadsheet Google Docs application.
