Fight to Repair: A video from the FSF
What is GNU?
GNU is an operating system that is free software—that is, it respects users' freedom. The GNU operating system consists of GNU packages (programs specifically released by the GNU Project) as well as free software released by third parties. The development of GNU made it possible to use a computer without software that would trample your freedom.
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. Nonfree software puts its users under the power of the software's developer. See the video explanation.
What is Free 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:
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 can help.
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 packages.
The name “GNU” is a recursive acronym for “GNU's Not Unix.” “GNU” 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 talks 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.

UK universities find that many students are fed up with virtual courses and want to attend class physically. Others feel the opposite.
If you are a student, or have been admitted, and you are disgusted with being forced to use nonfree software for school, now is your chance to make a difference — tell the university you don't want to do that. Be civil to the staff, but show how strongly you feel this.
GNU and FSF move official IRC channels to Libera.Chat network. Read the full announcement and the follow-up update.
The GNU Project supports the Free Software Foundation's petition to call on school administrators around the world to stop requiring students to run nonfree software. Sign the petition for freedom in the classroom.
The GNU Project strongly urges the community to communicate in ways that are friendly, welcoming and kind. See the GNU Kind Communications Guidelines.

grep is a tool for finding text inside files. Text is found by matching a pattern provided by the user in one or many files. The pattern may be provided as a basic or extended regular expression, or as fixed strings. By default, the matching text is simply printed to the screen, however the output can be greatly customized to include, for example, line numbers. GNU grep offers many extensions over the standard utility, including, for example, recursive directory searching. (doc)
