Books on Using UnixThese can help you get started with interactive use of the shell and tools like grep and vi.
"Teach Yourself Unix in 24 Hours", 3rd edition, by Dave Taylor. Good for folks who want a structured approach. Links: author's page, example chapter, fatbrain.com, Amazon.
"Think UNIX", by Jon Lasser. A slightly more advanced introduction to Unix anno 2000. Links: author's page.
"The Unix Programming Environment", by Kernighan and Pike. A good introduction to Unix anno 1984. It's a bit like reading Middle English. Don't buy it new -- but if you find a copy cheap, read it to see what Unix looked like before graphics and the Internet, and what C programming looked like before ANSI C.

Inter-process communication :
Inter-Process Communication (IPC) is a set of techniques for the exchange of data among two or more threads in one or more processes. Processes may be running on one or more computers connected by a network. IPC techniques are divided into methods for message passing, synchronization, shared memory, and remote procedure calls (RPC). The method of IPC used may vary based on the bandwidth and latency of communication between the threads, and the type of data being communicated.
IPC may also be referred to as inter-thread communication and inter-application communication.
IPC, on pair with the address space concept, is the foundation for address space independence/isolation.[1]

The Creation of the UNIX* Operating System
After three decades of use, the UNIX* computer operating system from Bell Labs is still regarded as one of the most powerful, versatile, and flexible operating systems (OS) in the computer world. Its popularity is due to many factors, including its ability to run a wide variety of machines, from micros to supercomputers, and its portability -- all of which led to its adoption by many manufacturers.
Like another legendary creature whose name also ends in 'x,' UNIX rose from the ashes of a multi-organizational effort in the early 1960s to develop a dependable timesharing operating system.
The joint effort was not successful, but a few survivors from Bell Labs tried again, and what followed was a system that offers its users a work environment that has been described as "of unusual simplicity, power, and elegance...."
The system also fostered a distinctive approach to software design -- solving a problem by interconnecting simpler tools, rather than creating large monolithic application programs.
Its development and evolution led to a new philosophy of computing, and it has been a never-ending source of both challenges and joy to programmers around the world.

MontaVista Linux Professional Edition 3.1 Preview Kit
We no longer support the preview kit for MontaVista Linux Professional Edition 3.1.
The current version of MontaVista Pro is 5.0, and you can preview it without installing software by using MontaVista TestDrive.
MontaVista TestDrive enables you to evaluate your applications on MontaVista development tools and OS with your choice of processor architecture.
Please click here to find out about MontaVista TestDrive previews.
If you want to learn more about the latest version of MontaVista Linux Professional Edition, start with this page.
Thank you.
unix introduction tips
this blog gives tips about software updates
Unix (officially trademarked as UNIX®, sometimes also written as Unix or Unix® with small caps) is a computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs including Ken Thompson, Dennis Ritchie and Douglas McIlroy. Today's Unix systems are split into various branches, developed over time by AT&T as well as various commercial vendors and non-profit organizations.
As of 2007, the owner of the trademark UNIX® is The Open Group, an industry standards consortium. Only systems fully compliant with and certified to the Single UNIX Specification qualify as "UNIX®" (others are called "Unix system-like" or "Unix-like").
During the late 1970s and early 1980s, the influence of Unix, in academic circles, led to large-scale adoption of Unix (particularly of the BSD variant, originating from the University of California, Berkeley) by commercial startups, the most notable of which is Sun Microsystems. Today, in addition to certified Unix systems, Unix-like operating systems such as Linux and BSD are commonly encountered. Sometimes, "traditional Unix" may be used to describe a Unix or an operating system that has the characteristics of either Version 7 Unix or UNIX System V.
