Linux On The Desktop?
In practice, however, strategic software decisions are made based on more than just
technical issues. Proposing a solution used by just 1 % of people could be consid
ered foolhardy. But there's a lot at stake. If you refuse to countenance other solutions
you'll be handing control of the desktop and your IT budget to Microsoft for the
foreseeable future.
Not Unix?
Linux is part of the GNU Project, set up during the 1980s to create a free clone of the
Unix operating system. It is released under a software licence the GNU General
Public License (GPL) that ensures you can install as many copies as you like without
paying a fee for each one. You also get free access to the source code, which is more
useful than you might think if you ever come up against what seems to be a bug in
the OS.
Linux is a multi user, multi tasking operating system that runs on a wide variety of
hardware. As a desktop OS it has broadly comparable capabilities to Windows NT
and 2000. Security is good. Ordinary users can only write to private work areas
(stored under the directory/home), which are normally kept on a separate partition
or drive. This makes it easy to organise backups, as well as facilitating access via a
network.
Every aspect of a Linux system can be controlled using text based configuration files
and command line utilities. These can be automated using a wide range of scripting
tools, from industry standard Unix shells to script languages like Perl and Python.
It isn't hard, once you've mastered the principles, to develop your own scripts to
automate system management. The major Linux distributions such as Red Hat and
SuSE include tools for automated deployment, much as you may be used to using
to roll out installations of Windows. Linux hasn't been just a hackers' plaything for
years.
Desktops
Linux offers a range of graphical environments for desktop users. The most suitable
for ordinary office use are KDE or GNOME. GNOME (GNU Object Model Environ
ment) looks attractive and has some elegant design concepts, but KDE (K Desktop
Environment) is more mature, more stable and looks more functional. Each has been
created using a different set of programming libraries, and has native applications
and accessories that use these same libraries. The choice of environment doesn't
