I think it is more clear if "ipcs -m" outputs only one line for each shared memory and it gets more similarity with "ipcs -s" and "ipcs -q". Actually, there are a lot of information about shared memory like below. [root@localhost ipcs]# ipcs -i 0 -m Shared memory Segment shmid=0 uid=0 gid=0 cuid=0 cgid=0 mode=0666 access_perms=0666 bytes=90000 lpid=30412 cpid=30412 nattch=0 att_time=Thu Apr 19 10:55:34 2012 det_time=Fri Apr 20 11:39:06 2012 change_time=Thu Apr 19 10:55:34 2012 Maybe later, we will need not only PAGES and VFS_INODE. We may need some information about time. So keeping -M option is necessary.

P.S. the two useless item has been removed, please refer to the attachment.
