How do two different programs written in other languages communicate with each other? You will probably find perlipc useful.	[reply]

There are a multitude of ways in which two Perl programs may communicate with one another. I think you'll find a read-though of perlipc to be most helpful, as well as perusing the standard books. Hope this helped, -v. "Perl. There is no substitute."	[reply]

Basically you have pipes, sockets, shared thread variables, or shared memory. Shared Memory is the fastest, but most difficult. Sockets are probably the most reliable and well tested. I'm not really a human, but I play one on earth. Cogito ergo sum a bum	[reply]

Hi, I think is also worth to mention ways to communicate over sockets like XML-RPC, SOAP, Jabber, CORBA, BEEP, and a large of etceteras ;-) Regards, fmerges at irc.freenode.net	[reply]

You want the perl scripts to send oneanother jabber messages when they complete their tasks? mailer.pl> i'm done, over to you backend.pl> Ok, great, i'll start on that mailer.pl> let me know when you're done. backend> Sure, will do ^_^ Hrm, I smell botnet will: do{ perl programming } for $cash;	[reply]

Hi, I see you don't have any idea of what Jabber really is! XMPP is a set of protocols expressed within XML. XMPP provides a structured, extensible framework for exchanging all kinds of information. It provides you with Synchronous, Request/Response, and also Asynchronous Framework. It has Component/Service Architecture. As XML-RPC and SOAP are also XML based, RPC can go through XMPP messages, getting all the benefits that the Jabber server and the XMPP protocols can provide. And you can also define your own protocol, because there are only a few restricted tags that Jabber uses itself, so there is space for defining something that only process your business logic. So, I recommend you doing a research first and then write comments... Ahh, there're also nice books about Jabber, for example: Jabber's Developer Handbook Programming Jabber Regards, fmerges at irc.freenode.net	[reply]

OK, not helpful, i get the point.	[reply]

I would be curious to understand what it means for two Perl programs to be "mutually exclusive". But that's probably not relevant here...	[reply]

and just for the record: the language is called Perl...	[reply]

IPC::Open3::Simple is my new favourite. Though the method you use will depend on how and when these scripts want to talk to each other. Not enough context to suggest an optimal solution.	[reply]

{snip} how two mutually exclusive PERL programs can communicate by sending signals to each other. Although you probably meant "signals" in the standard Unixy sense, in the more generic sense (and if the Perl programs are running on different machines, and if they don't need to talk to each other very often), I've seen email messages used for inter-app communication -- and it didn't work too badly either. :) Granted, it's not optimal, and there's often better solutions out there, but it's a hack I've seen done.
