The +.Dq maximum allowed size +is the maximum number of bytes in a message on a message queue, +the size of a shared memory segment, +or the number of semaphores in a set of semaphores. +.It Fl c +Show the creator's name and group for active semaphores, message queues, +and shared memory segments. +.It Fl M +Display system information about shared memory. +.It Fl m +Display information about active shared memory segments. +.It Fl o +Show outstanding usage for active message queues, +and shared memory segments. The +.Dq outstanding usage +is the number of messages in a message queue, or the number +of processes attached to a shared memory segment. +.It Fl p +Show the process ID information for active semaphores, message queues, +and shared memory segments. The +.Dq process ID information +is the last process to send a message to or receive a message from +a message queue, +the process that created a semaphore, or the last process to attach +or detach a shared memory segment. +.It Fl Q +Display system information about messages queues. +.It Fl q +Display information about active message queues. +.It Fl S +Display system information about semaphores. +.It Fl s +Display information about active semaphores. +.It Fl T +Display system information about shared memory, message queues +and semaphores. +.It Fl t +Show access times for active semaphores, message queues, +and shared memory segments. The access times is the time +of the last control operation on an IPC object, +the last send or receive of a message, +the last attach or detach of a shared memory segment, +or the last operation on a semaphore. +.El +.Pp +If none of the +.Fl M , +.Fl m , +.Fl Q , +.Fl q , +.Fl S , +or +.Fl s +options are specified, information about all active IPC facilities is +listed. +.Sh RESTRICTIONS +System data structures may change while +.Nm ipcs +is running; the output of +.Nm ipcs +is not guaranteed to be consistent. +.Sh BUGS +This manual page is woefully incomplete, because it does not +at all attempt to explain the information printed by +.Nm ipcs . +.Sh SEE ALSO +.Xr ipcrm 1 +.Sh AUTHORS +.An Thorsten Lockert Aq tholo@sigmasoft.com |
