Command-line processing with getopt()
All UNIX(R) programs, even those with graphical user interfaces (GUIs), accept and process command-line options. For some programs, this is the primary means of interacting with either other programs, or users. Having robust handling of complex command-line arguments makes your application better and more useful. And yet, many developers are spending their precious time writing their own command-line parsers instead of using getopt(), a library function designed specifically to ease the burden of command-line processing. Read on to learn how to use getopt() to record your command-line arguments in a global structure that can then be used throughout your program whenever appropriate.

Comparison of SLES (SUSE) and RHEL (Red Hat) on IBM System p
Most system administrators planning to install Linux on IBM System p eventually run into an important question: Which Linux distribution should I install? This article compares two distributions from Red Hat and Novell, and weighs the pros and cons of each. We'll discuss Linux on POWER (LoP), the history of both distributions, the relationship IBM has with them, and the factors that should go into your decision-making process. We're also going to compare and contrast what it takes to create logical volumes on SuSE Linux Enterprise Server (SLES) and Red Hat Enterprise Linux (RHEL).
