You should take a look at ttp://www.linux-mag.com/id/5103

"Boot Camp for Wizards, Part Three: Using Standard I/O from shells"

you can use named pipes and I/O redirection for IPC. I don't know how Jerry would be able to getdeeper on IPC at the shell level, I guess you'll need a more complete programming language for message passing, queues, semaphores and shared memory .

A Wizard article for deciding swap size would be great. How to find out what an application requires for swap rather than the operating system would be very useful and how memory is allocated to processes.

Great series so far.

The HUP signal can be very handy.

I’ve found that most command shells catch this signal and try to terminate as quickly as possible. This applies to unconventional shells like IBM’s UniVerse and JBases (both are dialects of Pick running on Unix). If you have a number of processes stuck and you need to try to kill them as gently as possible, the HUP signal is a good starting point.
