Questions specifically about Linux but not specific to a particular distribution. If the question could apply to any Unix-like system, specify your Linux distribution in the body of your question but do not use the /linux tag.

In a narrow sense, Linux is a Unix-like kernel started by Linus Torvalds in 1991. For questions that are specifically about the kernel (e.g. how to configure and build it), use the tag .

In common usage, Linux is an operating system built around the Linux kernel. This operating system includes many other components, notably from the GNU project, so the term GNU/Linux is sometimes used. There are many different Linux distributions (see ), including more or less the same programs but with different installers (see ) and other customizations.

Use this tag for questions that are specific to Linux-the-operating-system, such as hardware support, networking setup, filesystems, etc. Most questions should have other tags to identify the area of interest, e.g. , , , , , etc.

The Linux kernel is used in some non-unix-like embedded operating systems, the best known being Android. These operating systems are off-topic here (you can ask questions about using Android on Android Stack Exchange.
