UNIX has hundreds if not thousands of commands, and it's impossible to remember every option and nuance. But, happily, you don't have to: man, UNIX's built-in, online reference system, is man's best friend. Take a look at this shortcut guide to the UNIX man pages system.

This tip explains how server virtualization will benefit Linux and Unix operating system adoption but will most likely harm Windows Server adoption by relieving the one-operating-system-to-one-server modus operandi. You'll review the drawbacks of using Windows operating systems and the rewards that virtualization offers to not only IT architects but end-users and application vendors and learn how these factors will combine and affect the current use of Linux, Unix and Windows operating systems.

We are very familiar with Linux and its relation with UNIX.But most us of dont actually know what are differnces between the two.
Linux is called Unix-like and is not a true Unix operating system.

Whenever people thinks of a free operating system (if they do), the odds are that they will think of Linux, a clone of UNIX from 1991. They also might think of one or more of the BSDs, UNIX-derivatives dating back to the early ’80s. Let’s face it, though—UNIX is pretty boring. It was great for a PDP-11, and it gets the job done now, but it’s not exactly exciting.

A federal court in Utah ruled that Novell Inc., not SCO Group Inc., is the rightful owner of the copyright in the Unix operating system.

The ruling is a boon to the "open source" software movement and to Linux, the freely available computer operating system that has become an alternative to Microsoft Corp.'s Windows operating system.

I’ve pretty much assumed that technologically speaking, if Windows has it, Unix and the like must also have the same functionality. As I re-engage with Unix and Linux developers and IT professionals in recent months, though, I can see that there are some areas – particularly in security - where Windows is far ahead of the *x operating systems. Here’s a few...

What's the big deal about Linux? Isn't it at heart just a PC-based version of UNIX – the ‘70’s hit operating system which has outlived the predictions of its demise throughout the ‘90’s? If you’ve come from a Solaris or HP/UX or AIX background isn’t a PC-based UNIX a bit, well, passé?

Anti-virus software has become a critical aspect of computing at all levels. Although to this point it seems the only operating system that is really targeted by viruses is Microsoft Windows, the time will come when UNIX-based operating systems will be equally as marked.
