There's probably a reason why you want to process that file - splitting it can be a problem if you need to keep track of some states and it splits on the wrong line. So, I'd probably open it in perl (or whatever processor) directly and use a database for storage if I really need to keep string contexts, so that on each line iteration my perl memory is clean. -- Mel _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
