So you want to start programming UNIX shells. You could sit down with a dense volume of coding advice, but you're a techie. You want to jump right in and start coding. This chapter will help you get started right away with shell programming in UNIX.
Some time back, I promised to double-check Sun executive Larry Singer’s “Reality Check” missives on HP. A week ago, Mr. Singer penned a Reality Check that, in light of HP’s decision to cancel its TruCluster integration effort, does in fact reflect more reality than rhetoric. It also reflects Mr. Singer’s opinions, some of which differ from mine. Presented herewith is Larry’s write-up, laced with a few comments of my own.
Early Wednesday morning 1 December, our colleagues at The Inquirer ran a story entitled “HP expected to drop Trucluster from HP-UX” on their web site. According to the story, unnamed sources claimed that HP soon will announce that TruCluster technology is unlikely to be incorporated into HP-UX. More here.
Charles Keenan provides specific tasks for setting up a Serviceguard high availability cluster on HP-UX/Linux, including example commands to help illustrate key points.
The operating system family that powers the lion's share of servers is losing ground to Windows and Linux. Unix is losing so much ground that IT research firm IDC is predicting Windows will take over as the dominant server operating system by the year 2008.
Expose the power of Bash shell, tutorial here.
This quick guide is based on true story, and is contributed to the community with the intent to be helpful to the department, office and enterprise Managers, network Administrators and support Staff, and Small Business Owners.
Last Wednesday, IBM's AIX was the first to recieve the UNIX 2003 certification from The Open Group, beating out Sun, HP, SCO and the rest.
Peter Hall from HP has responded to Sun's Jonathan Schwartz. Apparently HP is still committed to the HP-UX operating system.
Optimizing the performance of a system can save your company a considerable amount of money. In this chapter, you'll see how to streamline your system for maximum efficiency.
Hewlett-Packard has formally demanded that Sun Microsystems and its president, Jonathan Schwartz, stop publishing what it calls "misleading and factually incorrect statements" about HP's commitment to its version of Unix--but Sun is standing firm.
HP has sent a letter to Sun that complains about the inflammatory nature of Jonathan Schwartz's Weblog entries, according to this report. Apparently it is in response to Schwartz saying that HP's Unix operating system is dying.
OneFinger is a general-purpose GUI for composing CLI commands with the mouse. Although entirely graphical, it does not attempt to hide the underlying CLI language. Requires Python for Qt3.
Some intrepid soul has ported the SIMH emulator to the GBA and is using that to run the PDP-6 version of UNIX v6. Actually, looking at the stats of the (ARM-based) GBA, it would have been eye-poppingly advanced back in the late 60s. There's a great article about it at Kernelthread. Update: Thanks to Vanders on setting me straight on which version of UNIX was actually ported.
HP World HP will be a pitching a story of Unix harmony and advancement at its HP World user conference here this week. First up, HP has now released HP-UX 11i V2 for both its Itanium and PA-RISC based servers. This means PA-RISC customers no longer have to wait until HP-UX 11i V3 arrives to use the same operating system as their Itanium counterparts. The bad news, however, is that both sets of customers will have to wait until the second half of next year to get their hands on V3 - a product once due at the end of this year.
This paper is meant to serve as an introductory guide to the basic security and server hardening functions present in AIX. Many of the features and functions shown throughout this guide are applicable to AIX 4.3 and above, but are more directed toward AIX 5.2. This guide attempts to cover a lot of ground and offers useful and necessary insight for anyone administering AIX machines.
Linux can learn valuable lessons from its elder cousins in the enterprise, the proprietary Unixes from the likes of IBM, Sun, and HP. Those operating systems, in turn, can learn some lessons from Linux. Comparing the features of the more enterprise-ready Linux distros with AIX, one of the leading proprietary Unixes, helps identify some.
The HP-UX kernel is a multitasking, multiuser, multiprocessor, multithreaded, load-leveling, supercalifragilisticexpialidocious modular operating system with real-time scheduling extensions. To get a handle on it, read this introduction to the basic organization of the kernel and its data structures.
Analysts report that the shift toward both Linux and Windows dominance in the data center has begun and traditional UNIX is on the way out.
With the publication of 'Advanced UNIX Programming', Second Edition, Marc Rochkind takes a look at what has changed in the 20 years since he wrote the first edition.
