if the target is a unix box you can use the diff to make a patch file that you can use w/ 'patch' (not a nsh command though).
why can't you just copy over the new version of the file ?
Its Windows boxes
And each customer file can be different
So we need to Patch and not run other it
I created a NSH script using some complex sed commands
Will test it soon
What is different between these files? like is it stuff that should be moved into a properties file or something that would be eaiser to handle w/ a cfo ?
