in reply to How can I read DATA in parent and child?

I wonder what you really want to do. As far as I understood you want to read from a file from two different processes, right? The use of <DATA> is just a simplification.

Please correct me if i‘m wrong.

You may consider to use MCE::Hobo. If you don‘t use threads it forks.

Please see Re: Parallel trigger of different subs as well as the whole thread ibidem for inspiration.

Minor update: Fixed typo.

Best Regards, Karl
