Resources may be specified as follows:

−m

shared memory segments

message queues

−s

semaphore arrays

−a

all (this is the default)

The output format may be specified as follows:

−t

summary

ipcrm(1), ipcmk(1)

The Linux ipcs utility is not fully compatible to the POSIX ipcs utility. The Linux version does not support the −b and −o options, but does support the −l and −u options not defined by POSIX. The portable application shall not use the −a, −b, −o, −l, and −u options.
