UNIX for Dummies Questions & Answers

Does anyone know how to set the variables with the ipcs command?

I need to set the following variables:
Shared memory segments
message queues
semaphore arrays
all of these

ipcs simply reports information on IPC resources.

There is no "command line" way to change the values for the
IPC resources (and there shouldn't be). Depending on the
system you are running, you may be able just to change the
system tunable parameter values and reboot. On other systems
however, you may have to edit the system tunable parameters
and rebuild your kernel. This procedure is extremly system/OS
dependent and not recommended if you are new to UNIX.
You can render your system unbootable if you make a mistake
(or at the very least, hose up system performance). If nobody
but you relies or accesses the system then feel free to
expierement but be ready to do alot of reading.
