Linux 2.6.28 (2.6 branch)
Linux is a clone of the Unix kernel, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX and Single UNIX Specification compliance. It has all the features you would expect in a modern fully-fledged Unix kernel, including true multitasking, virtual memory, shared libraries, demand loading, shared copy-on-write executables, proper memory management, and TCP/IP networking. License: GNU General Public License (GPL)Changes:
This version adds support for the Ext4 filesystem, Ultra Wide Band (Wireless USB, UWB-IP), memory performance improvements, a boot tracer, disk shock protection, the phonet network protocol, support for SSD discard requests, transparent proxy support, several new network drivers, controllable IO CPU affinity, high-resolution poll()/select(), support of a minimal "dummy" policy in SELinux, tracing improvements, x86 x2APIC support, a fb driver for VIA UniChrome devices, Mitac Mio A701 ARM-based smartphone support, some new drivers, and many small improvements and fixes.Image

ipcs

IPCS(1) 						     Linux Programmer's Manual							   IPCS(1)

NAME

       ipcs - provide information on ipc facilities

SYNOPSIS

       ipcs [-asmq] [-tclup]
       ipcs [-smq] -i id
       ipcs -h

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

SEE ALSO

       ipcrm(1), ipcmk(1)

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.
