pcp-ipcs [resource-option] [output-format] pcp-ipcs [resource-option] -i id
pcp-ipcs provides information on the inter-process communication facilities for which the calling process has read access.
-i, --id id Print details only on the resource identified by id. -h, --help Display a help text and exit. -V, --version Display version information and exit. Resource options -q, --queues Write information about active message queues. -m, --shmems Write information about active shared memory segments. -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() and msgrcv() operations on message queues, the time of the last shmat() and shmdt() operations on shared memory, and the time of the last semop() 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 pcp-ipcs utility is not fully compatible to the POSIX pcp-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.
