lsipc [options]
lsipc shows information on the System V inter-process communication facilities for which the calling process has read access.
−i, −−id idShow 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. It is possible to override
the default output format for this option with the
−−list,
−−raw,
−−json or
−−export
option.
−g, −−globalShow system-wide usage and limits of IPC resources.
This option may be combined with one of the three
resource options: −m,
−q or −s. The default is to show
information about all resources.
−h, −−helpDisplay help text and exit.
−V, −−versionDisplay version information and exit.
−m, −−shmemsWrite information about active shared memory segments.
−q, −−queuesWrite information about active message queues.
−s, −−semaphoresWrite information about active semaphore sets.
−c, −−creatorShow creator and owner.
−e, −−exportOutput data in the format of NAME=VALUE.
−J, −−jsonUse the JSON output format.
−l, −−listUse the list output format. This is the default,

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 memory, and the time of the last semop(2) operation on semaphores.
−−time−format
