join command in perl?

[Benjamin Cheong]

Hi all,

Basically, what I'm trying to do is compare two large CSV files and find out which fields have changed since the last update. Based on that, I want to produce comparison files based on which field was different.

I know of a way to do this using the 'join' command in HP-UX (please see http://www.opengroup.org/onlinepubs/009695399/utilities/join.html for details), but I would like to do this in Perl.

Would appreciate any help!

Cheers,
Ben

you can use two hashes and use the `key' fields as hash key (maybe packed - see perldoc -f pack), and compare the values for each key that occurs in both hashes

Have a look at CPAN modules Text::CSV_XS and Text::Diff

Enjoy, Have FUN! H.Merijn
