Co je GNU?
GNU is an operating system that is free
software—that is, it respects users' freedom. The development of
GNU made it possible to use a computer without software that would trample
We recommend installable versions of
GNU (more precisely, GNU/Linux distributions) which are entirely free
software. More about GNU below.
What is the Free Software Movement?
The free software movement campaigns to win for the users of computing the
freedom that comes from free software. Free software puts its users in
control of their own computing. Non-free software puts its users under the
power of the software's developer. See the
Co je to svobodný software?
Free software means the users have the freedom to run, copy,
distribute, study, change and improve the software.
Free software is a matter of liberty, not price. To understand the concept,
you should think of “free” as in “free speech”, not
as in “free beer”.
More precisely, free software means users of a program have the four essential freedoms:
- Spouštět program dle svého přání, za libovolným účelem (svoboda 0).
- Studovat, jak program funguje. Měnit ho, aby dělal, co chcete (svoboda
1). Předpokladem pro to je přístup ke zdrojovému kódu.
- Svoboda redistribuovat program, takže člověk může pomoci ostatním (svoboda
- Svoboda vylepšovat program a publikovat svoje vylepšené verze tak, aby z
nich měla užitek celá komunita (svoboda 3). Předpokladem pro to je přístup
ke zdrojovému kódu.
Developments in technology and network use have made these freedoms even more
important now than they were in 1983.
Nowadays the free software movement goes far beyond developing the GNU
system. See the Free Software Foundation's web
site for more about what we do, and a list of ways you
More about GNU
GNU is a Unix-like operating system. That means it is
a collection of many programs: applications, libraries, developer tools,
even games. The development of GNU, started in January 1984, is known as
the GNU Project. Many of the programs in GNU are released under the
auspices of the GNU Project; those we call GNU
The name “GNU” is a recursive acronym for “GNU's Not
is pronounced g'noo, as one syllable, like saying
“grew” but replacing the r with n.
The program in a Unix-like system that allocates machine resources and talk
to the hardware is called the “kernel”. GNU is typically used
with a kernel called Linux. This combination is the GNU/Linux operating
system. GNU/Linux is used by millions, though many call it “Linux” by mistake.
GNU's own kernel, The Hurd, was
started in 1990 (before Linux was started). Volunteers continue developing
the Hurd because it is an interesting technical project.

GNU Recutils is a set of tools and libraries for creating and manipulating
text-based, human-editable databases. Despite being text-based, databases
created with Recutils carry all of the expected features such as unique
fields, primary keys, time stamps and more. Many different field types
are supported, as is encryption.
