| |
| == 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*. It is possible to override the default output format for this option with the *--list*, *--raw*, *--json* or *--export* option. |
| |
| *-g*, *--global*:: |
| Show 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*, *--help*:: |
| Display help text and exit. |
| |
| *-V*, *--version*:: |
| Display version information and exit. |
| |
| === Resource options |

| *-s*, *--semaphores*:: |
| Write information about active semaphore sets. |
| |
| === Output formatting |
| |
| *-c*, *--creator*:: |
| Show creator and owner. |

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* _type_:: |
| Display dates in short, full or iso format. The default is short, this time format is designed to be space efficient and human readable. |
