The Linux pcp-ipcs utility is not fully compatible to the POSIX pcp-ipcs utility.
The Linux version does not support the POSIX

.B \-o
options, but does support the
.B \-l
and
.B \-u
options not defined by POSIX.  A portable application shall not use the
.BR \-a ,
.BR \-b ,
.BR \-o ,
.BR \-l ,
and
.B \-u
options.
