Description of problem: The ipcs manpage states: The ipcs utility accepts the following options: [...] If -q, -m, or -s are specified, only information about those facilities shall be written. If none of these three are specified, information about all three shall be written subject to the following options: [...] -a Use all print options. (This is a shorthand notation for -b, -c, -o, -p, and -t.) -b Write information on maximum allowable size. (Maximum number of bytes in messages on queue for message queues, size of segments for shared memory, and number of semaphores in each set for semaphores.) However the -b option does not appear to be valid: # ipcs -b ipcs: invalid option -- b usage : ipcs -asmq -tclup ipcs [-s -m -q] -i id ipcs -h for help. This reference should be removed from the man page. Version-Release number of selected component (if applicable): util-linux-2.13-0.56.el5.x86_64 How reproducible: Always Steps to Reproduce: # man ipcs # ipcs -b Actual results: Manpage lists an option that does not work Expected results: Manpage lists only valid options
This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux. Because the affected component is not scheduled to be updated in the current release, Red Hat is unfortunately unable to address this request at this time. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux.

If none of these three are specified, information about all > three shall be written subject to the following options: This text is from POSIX ipcs(1p) from man-pages package, not from ipcs(8) from util-linux package. Try "man 8 ipcs" and "man 1p ipcs". The util-linux man page does not contain any information about the -b option. Anyway, util-linux upstream solution is to move the ipcs and ipcrm man pages from section 8 to the section 1.
