ipcmk(1) make various IPC resources


ipcmk [options]


ipcmk allows you to create shared memory segments, message queues, and semaphore arrays.


Resources can be specified with these options:
-M, --shmem size
Create a shared memory segment of size bytes. The size argument may be followed by the multiplicative suffixes KiB (=1024), MiB (=1024*1024), and so on for GiB, etc. (the "iB" is optional, e.g., "K" has the same meaning as "KiB") or the suffixes KB (=1000), MB (=1000*1000), and so on for GB, etc.
-Q, --queue
Create a message queue.
-S, --semaphore number
Create a semaphore array with number of elements.

Other options are:

-p, --mode mode
Access permissions for the resource. Default is 0644.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.
