Adopt Python to manage UNIX systems while incorporating concepts of
good program design. Python is an easy-to-learn, open source scripting
language that lets system administrators do their job more quickly. It can
also make tasks more fun.
This free tool gives you a huge amount of information all on one screen. Even
though IBM doesn't officially support the tool and you must use it at your own
risk, you can get a wealth of performance statistics. Why use five or six
tools when one free tool can give you everything you need?
Do you ever feel you wish you could answer some of your own questions when
you work with AIX and your System p™ server? Do you ever feel you
could save time by not having to call on the support professionals all the
time? Well, wish no more. Shiv Dutta discusses some of the AIX commands that
answer those questions and tells you how to enlarge the list of such answers.
Explore the vast terrain of the UNIX file system with the find command. One
of the most powerful and useful commands in the UNIX programmer's repertoire
is find. All flavors of UNIX have file systems that can contain thousands of
files of many different types. With so many choices, locating a specific file,
or set of files, can be difficult. The find command makes this task easier in
many ways.
Adopt 10 good habits that improve your UNIX command line efficiency—and break
away from bad usage patterns in the process. This article takes you
step-by-step through several good, but too often neglected, techniques for
command-line operations. Learn about common errors and how to overcome them,
so you can learn exactly why these UNIX habits are worth picking up.
Use Secure Shell (SSH) to run commands on remote UNIX systems and, with some
simple scripts, put together a system that enables you to manage many systems
simultaneously from one machine without having to log in directly to the
machines themselves. Also examine the basics of a distributed management
system and some scripts and solutions using the technique.
Searching for an easy way to create high-quality graphs that you can print,
publish to the Web, or cut and paste into performance reports? Look no
further. The nmon_analyser tool takes files produced by the NMON performance
tool, turns them into Microsoft Excel spreadsheets, and automatically produces
these graphs.
If your UNIX system lacks a tool you need, chances are you can find an apt solution in the enormous inventory of software available online. This month, learn how to build software from source code.
Software programs are often made to run on systems that are completely
different from the system in which the program is coded or developed. This
process of adapting software across systems is known as porting. You might
need to port software for any one of several reasons. Perhaps your end users
want to use the software in a new environment, such as a different version of
UNIX, or perhaps your developers are integrating their own code into the
software to optimize it for your organization's platform.
If you have UNIX-based programming experience, then you've probably
worried at some point about enhancing your network throughput. In this
article, learn some useful techniques to squeeze the most out of your
bandwidth, and get a big performance boost with some of the methods described
here.
