How do I process captured output from `tail` without reprocessing?

Question

Hi, I want to excecute a tail command in Unix for indefinite time and capture its output in a Perl script, process it and store certain data into a database. But it should be live, meaning old data – once stored in the database – shouldn't be reprocessed. It should only capture, and process only the most recent output.

Can someone please tell me how can this be done? Thanks in anticipation.

Try File::Tail which can handle multiple files at same time.
