SYNOPSIS

DESCRIPTION

       ipcs  provides  information  on  the ipc facilities for which the calling process has read
       access.

       The -i option allows a specific resource id to be specified.  Only information on this  id
       will be printed.

       Resources may be specified as follows:

       -m     shared memory segments

       -q     message queues

       -s     semaphore arrays

       -a     all (this is the default)

       The output format may be specified as follows:

       -t     time

       -p     pid

       -c     creator

       -l     limits

       -u     summary

CONFORMING TO

       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 -a, -b, -o, -l, and -u
       options.
