  The Creation of the UNIX Operating System: An Overview of the UNIX* Operating System   (Site not responding. Last check: 2007-10-13)
Although UNIX was developed by programmers for programmers, it provides an environment so powerful and flexible that it is found in businesses, sciences, academia, and industry.
A major contribution of the UNIX system was its portability, permitting it to move from one brand of computer to another with a minimum of code changes.
UNIX e-mail at first permitted users on the same computer to communicate with each other via their terminals.

 Nice (Unix) - Wikipedia, the free encyclopedia
nice directly maps to a kernel call of the same name.
A nice value of −20 is the highest priority and 19 is the lowest priority.
Nice becomes useful when several processes are demanding more resources than the CPU can provide.

 nice
The nice utility invokes a utility, requesting that it be run with a different system scheduling priority (see the definition of system scheduling priority in the XBD specification, Glossary).
The nice utility supports the XBD specification, Utility Syntax Guidelines except that the obsolescent version allows a multi-digit decimal integer as an option name.
The command, env, nice, nohup, time and xargs utilities have been specified to use exit code 127 if an error occurs so that applications can distinguish "failure to find a utility" from "invoked utility exited with an error indication".

 ITworld.com - UNIX SYSTEM ADMINISTRATION - Being Nice
To understand what nice means with respect to scheduling, one has to know a little about the way that the system scheduler (an essential part of the kernel or "core" of the operating system) selects which process is to be run at any point in time.
One of the most difficult aspects of the simple nice and renice commands is that they do not necessarily agree on whether the renice argument is a decrement to the priority or an absolute value.
Though nicing our processes may be "old hat" (not another pun!), the habit might come back when systems get busy and some of us want to run some tasks while taking little in terms of resources from more important work.

 The UNIX Forums - Please Help Me With This Nice And Renice Stuff   (Site not responding. Last check: 2007-10-13)
First of all, nice is only used when you want to change the default priority level of the process that you are initiating.
Nice is used only at the time you kick off a script or a command from the command line to set the priority to something other than the default setting which is usually somewhere in the middle of the priority range.
In general for normal users, they can use the nice command but probably wouldn't because they have the best priority they can get with the default priority they are assigned, usually around +10 or so.

 NiCE | NiCE Admire: Administration GUI for HP OpenView Operations for Unix
NiCE Admire is a Java-based GUI, which allows multiple administrators of HP OpenView Operations for UNIX to log on and work in different, remote locations at the same time.
NiCE Admire was developed by HP OpenView experts, who understand the value of a user interface that is integrated, flexible, and easy to use.
NiCE Admire will be gradually enhanced with the objective of replacing the out-of-date Motif GUI of HP OpenView Operations for Unix entirely until the end of the year 2006.

 Apple - Mac OS X - UNIX
Beneath the surface of Mac OS X lies an industrial-strength UNIX foundation hard at work to ensure that your computing experience remains free of system crashes and compromised performance.
UNIX users will feel at home in Darwin, the robust BSD environment that underlies Mac OS X. That environment is accessible at any time from the Terminal application.
All of the standard UNIX utilities and scripting languages are included in Mac OS X: editors such as emacs, vim and even ed; file management tools such as cp, mv, ls and tar; shell scripts including bash (the default shell), tcsh (csh) and zsh.

 Using 'nice' to Sequentially Execute Jobs

 Basics of the Unix Philosophy
In our discussion of what Unix gets wrong, we observed that the designers of X made a basic decision to implement “mechanism, not policy”—to make X a generic graphics engine and leave decisions about user-interface style to toolkits and other levels of the system.
Unix programmers vie with each other for “simple and beautiful” honors — a point that's implicit in these rules, but is well worth making overt.
Unix experience tells us that the marginal extra overhead of making data layouts self-describing is paid back a thousandfold by the ability to evolve them forward without breaking things.

 OS X as a UNIX workstation (for Astronomers)   (Site not responding. Last check: 2007-10-13)
It is nice using a UNIX that is completely supported on the hardware by the manufacturer.
And as a bit of a UNIX geek, it is hard to turn down the chance to play with a new (and in a lot of ways different) UNIX that is modern and updated.
Even though normal PC keyboards have the caps lock key in the same stupid place as the powerbook keyboard (unlike the nice UNIX keyboards from Sun), I find that on the small powerbook keyboard, it is more of a problem for me. Apple does provide an easy way to change this.

 nice() -- adjust process priority
Is the increment to apply to the current nice value.
A request was made to change the nice value to a lower numeric value and the current process does not have appropriate privilege.
This is confusing, and somewhat contradictory with standard UNIX behavior.

 UNIX   (Site not responding. Last check: 2007-10-13)
UNIX and GCG are NOT synonyms, but one must be able to perform simple UNIX commands and understand UNIX file structure to use the GCG programs.
Generally, permissions on important files are set by the administrator and your file permission default is that you can write to, read from, or execute files in your home directory, but "other people" can only list your files.
UNIX programs (and GCG programs) will allow the user to modify execution with "flags", allow one to redirect input or output, and can be stopped if they are not what you would like to do.

 Developing Cross-Platform UNIX Applications with Mac OS X
The ability to do cross-platform development is a strength of Mac OS X, as the UNIX underpinnings make it easy to develop applications on your Mac and port them to other flavors of UNIX for deployment.
It would be nice to live in a world where there's only one platform to worry about.
The depth and maturity of the UNIX foundation of Mac OS X, as well as the large number of tools that are shared across many other platforms like Linux and Solaris (and which are even available on Windows), means that you've got a rich toolbox for creating cross platform applications.

 UNIX Tools for NT
For anyone who has to live with both UNIX and NT in their day-to-day lives, it can be some comfort to know that it is possible, with a little work, to make the two environments nearly the same with respect to certain tools.
Often printing methods for UNIX and NT vary widely, so it became necessary to have commonly formatted printed text, through a common mechanism.
Luckily, some nice UNIX tools have been ported to NT to facilitate a common way to generate these documents.

The following set of tutorials reflects an effort to give Unix programmers and programmers wanna-be a chance to get familiar with various aspects of programming on Unix-like systems, without the need to buy an expensive set of books and spending a lot of time in understanding lots of technical material.
The one assumption common to all tutorials (unless stated otherwise) is that you already know C programming on any system.
Note: The levels mentioned here are just to give one a basic idea of what they are sticking their head into, before they delve into the tutorial.
