ipcs - show information on IPC facilities
ipcs [options]
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.
Of these options only one takes effect: the last one specified.
These affect only the -l (--limits) option.

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.
The ipcs command is part of the util-linux package and is available from Linux Kernel Archive.
