A Linux User Group or Linux Users' Group (LUG) is a private, generally non-profit or not-for-profit organization that provides support and/or education for Linux users, particularly for inexperienced users. The term commonly refers to local groups that meet in person, but is also used to refer to online support groups that may have members spread over a very wide area and which do not organize, or which are not based around, physical meetings. Similar organizations such as FreeBSD User Group (BUG) exist, although many LUGs encompass FreeBSD and other free Unix-based operating systems.
