I have 2 large text files , one looks like this:
The other is a list of emails in single column format like this:
Is there a command to delete all the blahblah emails from text file 1 and replace them with the ones from text file 2?
Or maybe a linux version of 'Csved' which has the ability to add,remove,insert columns?
Thanks in advance.
(Im sure seymour Berkoff from La femme Nikita uses linux!)
