+.SH CONFORMING TO
+The Linux ipcs utility is not fully compatible to the POSIX ipcs utility.
+The Linux version does not support the POSIX
+.BR \-a ,
+.B \-b
+and
+.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.
