look up any word, like pussy:
Pronunciation: LIH-nucks or LIE-nucks

1. A reimplementation of the UNIX operating system kernel, written by Linus Torvalds, and distributed for free on the Internet. Linux has acheived remarkable compatibility with UNIX, from the point of view of a programmer compiling his software from the source code. Software originally written for UNIX can usually be compiled to run on Linux with no modifications. Linux binaries cannot run on UNIX systems that don't have Linux compatibility on purpose. Linux can be made to run binaries from SCO OpenServer via the Intel Binary Compatibility Standard (IBCS).

Linux is more compatible with UNIX systems that descend from UNIX System V than it is with BSD systems such as FreeBSD.

2. The Linux kernel, bundled with application programs like those that come with UNIX. When these applications are products of the Free Software Foundation, the combination is called GNU/Linux (the G in GNU is pronounced).

When the kernel is combined with applications, the result is called a Linux "distribution." Some distributions are commercially sold and have their own brand names.

3. A registered trademark of Linus Torvalds.

4. A religion practiced largely on the USENET newsgroup comp.os.linux.advocacy. The primary ritual of Linux is arguing endlessly with one of two denominations of Linux practitioners: Linux advocates, and Windows advocates, over whether or not Linux is better than Microsoft Windows. The arguments that make up the ritual can be divided into five categories: Linux sucks, Linux rules, Windows sucks, Microsoft sucks and personal insults.

Linux practitioners are even more fervent than computer users who engage in other so-called "religious wars" such as the classic EMACS vs. Vi.

3. A registered trademark of Linus Torvalds.

Linux (the operating system) looks and feels very much like Sun Solaris, despite the fact that it is not based on the original UNIX kernel, and even its shell commands are complete rewrites of the originals.

GNOME, the graphical interface of Solaris, was written for Linux first.

Since its inception in 1991, Linux has become the most popular UNIX-like operating system, beating Solaris, and even UNIX-based Mac OS X.

2. We have a web server running Red Hat ~.

An alternative operating system to that of windows or mac. Can be used for servers, mobile phones and digital tv recievers. Can be customised to suit the user. Is based on Unix, Written by Linus Torvalds.
There are about a hundred different versions of linux distributed to millions of people on billions of computers-so you can bet your ass that one os will be different from the next. Linux allows the user to re-program the software to suit them-this is how many software glitches are sorted out with one person programming one part of the system while another person focusses on another part. Windows only allows this to an extent (ie changing a user name or startup sounds or desktop background etc) so for this reason many software bugs cannot be fixed and hence windows being so unstable. Linux is good for driving mobile phones or powering servers but is impractical for use with the average computer gamer/secretary/photo editor. In other words, a person with programming experience would opt for Linux as they can customise it to suit them, whereas a person wishing to read email or surf net would opt for Windows or Mac as they will not have to know anything about programming first.
Newer versions of linux can make applications (ie Windows media player or Mac video editor) run with Linux.

Note: A particularly bad combination is: Dell computer, Pentium 4 CPU and Windows XP. Try switching the combination (ie fit an AMD Athlon CPU)-this i am pointing out as many unstabilities are rooted to the CPU and combination of hardware components, rather than the actual software itself.

At least linux isn't backing up the TCPA, fuckheads. If microsoft were in control all you could do on computers is sit on your ass and play your little games all day.

Linux is one of three major operating sysems (windows,mac, linux)
Linux is Free opposed to the others making pre installed laptops much much cheaper.
Linux also has no known viruses, is much cheaper, works MUCH FASTER and is barely exposed to crashes.
However it involves using other versions of everything such as MSN, Word and excel.
Many debate it bad and many debate it better.
YOU: ew why can't you nudge on msn?!
ME: *rolls eyes* linux version of msn...

Linux is NOT an OS (Operating System). Linux is the actual kernel from which the platformed distribution runs and obtains directions. The Linux kernel is an open source system which falls under the GNU General Public license. In essence, Linux is a compressed, open source platform of UNIX. The actual OS's (distributions or flavors) are gentoo, red hat, unbuntu, slackware (Although very similar to straight UNIX), mandrake, arch, debian, mandriva, etc.

The Linux kernel was designed and constructed by Linus Torvalds to provide a free, open source kernel for all computer lovers.
i.e. Microsoft XP is an OS. Microsoft also has a kernel which makes it run. Linux is the actual kernel for distributions like S.u.S.E. etc.

1. Hey, do you use Linux?
- What?

2. Hey, do you use Linux?
- I love that OS
You're stupid.

3. Hey, do you use Linux?
- Yes, why yes I do.
Righto, Chap. Well done.

Linux is a free operating system like free UNIXes. The most popular is Ubuntu(still), yet the even more stable Memphis Linux is what you really should have. The Russians and Chinese prefer Linux over Windows all the time. Most servers is either Ubuntu Server or CentOS. The WWW runs 60% Linux servers, because less viruses.

The most stable Linux ever created is usually always Slackware, yet no one heard of it (distro created back in 1994)

UNIX is obsolete in comparison.

Easier to operate than 2 years ago.
Person 1: I run Ubuntu Linux Server for my web server
Person 2: I run Cent OS, because its a free Red Hat Enterprise Linux OS.
Person 3: I'm a hardcore Linux user and I run Memphis Linux
