I've two documents that are the result of SQL Queries.
For exemple i've my Doc1.lst that is :
John1 0 Julien 10 Jules3 0 Julie 30
On this Doc1.lst, I used sed to have only the name part, so Doc2.lst is :
John1 Julien Jules3 Julie
I don't master enough the sed command to catch only the numbers, so I would like to know if there is a way to create a Doc3.lst that take the Doc1.lst and delete into it the content of Doc2.lst
It would be a sort of reversed catenate. By the way, if you have the sed command to catch only the numbers that would be great.
