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 −b
, −o
, −l
, and −u
options.
The ipcs command is part of the util-linux package and is available from Linux Kernel Archive
