I read the ipcs man page and am still very confused.
Basically, I just want to know whether the output from the ipcs command below means these are the current "TOTAL" memory usage in bytes on the server? Is this correct?
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 (1 Reply)

ipcs
IPCS(1) User Commands IPCS(1)NAME
ipcs - show information on IPC facilities
SYNOPSIS
ipcs [options]
DESCRIPTION
ipcs shows information on the inter-process communication facilities for which the calling process has read access. By default it shows
information about all three resources: shared memory segments, message queues, and semaphore arrays.
OPTIONS -i, --id id
Show full details on just the one resource element identified by id. This option needs to be combined with one of the three
resource options: -m, -q or -s.
-h, --help
Display help text and exit.
-V, --version
Display version information and exit.
Resource options
-m, --shmems
Write information about active shared memory segments.
-q, --queues
Write information about active message queues.
-s, --semaphores
Write information about active semaphore sets.
-a, --all
Write information about all three resources (default).
Output formats
Of these options only one takes effect: the last one specified.
-c, --creator
Show creator and owner.
-l, --limits
Show resource limits.
-p, --pid
Show PIDs of creator and last operator.
-t, --time
Write time information. The time of the last control operation that changed the access permissions for all facilities, the time of
the last msgsnd(2) and msgrcv(2) operations on message queues, the time of the last shmat(2) and shmdt(2) operations on shared mem-
ory, and the time of the last semop(2) operation on semaphores.
-u, --summary
Show status summary.
Representation
These affect only the -l (--limits) option.
-b, --bytes
Print sizes in bytes.
--human
Print sizes in human-readable format.

The Linux ipcs utility is not fully compatible to the POSIX ipcs utility. The Linux version does not support the POSIX -a, -b and -o
options, but does support the -l and -u options not defined by POSIX. A portable application shall not use the -a, -b, -o, -l, and -u
options.
