I have a unix script to check the Oralc alert log every 10 minutes. The concept is to use "diff" command to get the difference between the current alert log and the one that copied from 10 minutes ago. By doing this, I only need to review a small portion of the alert log and will never miss any important message inside the alert log.

However, how do you do "diff" on NT? Is there a compatible command of "diff" on NT?

Thank you.
