Diff Command is possible for me?

[admod]

Hi Friends,

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.

thankfully,
Anes P.A

You can pipe the output thru a sed/awk filter and remove any output that is not inserted data. Sorry that I don't have time to help you with that right now, but perhaps someone else on the forums can do that with some suggestions how. The diff command does allow you to determine what to output based upon regular expressions, but it won't differentiate between inserted, deleted, or changed data.

Hi Rubber man Friend,

I got a Solution through this : "Anyway, I would use 'comm' for this, see 'man comm', you'll probably use 'comm -13' or '-23'

Thanks For ur Help

Bye Anes
