I noticed the posting in URL : http://lowfatlinux.com/linux-compare-
files-diff.html .Is there a way to use the diff command between an older and a newer version of a file and only display the lines that have been added to the newer file and not the ones that have been removed without any of the explanation formatting, just the new lines. I'm trying to bypass the process of putting both files into a database and running an SQL "left join where old data is null" as I will need to do this on a regular basis.
Please let me know if my inquiry is not clear or needs further explanation.
Thank you in advance for any help you can provide.
