'''Red Hat Linux''' was a widely used [[Commercial software|commercial]] [[Open-source software|open-source]] [[Linux distribution]] created by [[Red Hat]] until its discontinuation in 2004.<ref>{{cite web|title=Free_Versions_of_Red_Hat_Linux_to_be_DiscontinuedFree Versions of Red Hat Linux to be Discontinued|url=http://www.fusionauthority.com/news/3946-free-versions-of-red-hat-linux-to-be-discontinued.htm|publisher=fusionauthority.com|access-date=2008-03-02|url-status=dead|archive-url=https://web.archive.org/web/20120207100441/http://www.fusionauthority.com/news/3946-free-versions-of-red-hat-linux-to-be-discontinued.htm|archive-date=2012-02-07}}</ref>
 
Early releases of Red Hat Linux were called '''Red Hat Commercial Linux'''. Red Hat published the first non-beta release in May 1995.<ref>{{cite web|url = https://fedoraproject.org/wiki/History_of_Red_Hat_Linux?rd=History|title = History of Red Hat Linux|access-date = 2018-07-14}}</ref><ref name = "smoogespace">{{cite web|url = https://www.smoogespace.com/documents/behind_the_names.html|publisher=smoogespace.com|title = The Truth Behind Red Hat/Fedora Names|access-date = 2018-07-14}}</ref> It was the first Linux distribution to useincluded the [[RPM Package Manager|Red Hat Package Manager]] as its packaging format, and over time RPM has served as the starting point for several other distributions, such as [[Mandriva Linux]] and [[Yellow Dog Linux]].
 
In 2003, Red Hat discontinued the Red Hat Linux line in favor of [[Red Hat Enterprise Linux]] (RHEL) for enterprise environments. [[Fedora Linux]], developed by the community-supported [[Fedora Project]] and sponsored by Red Hat, is a free-of-cost alternative intended for home use. Red Hat Linux 9, the final release, hit its official end-of-life on April 30, 2004, although updates were published for it through 2006 by the [[Fedora Legacy]] project until the updates were discontinued in early 2007.<ref>{{cite web|title=The Fedora Legacy Project|url=http://www.fedoralegacy.org/|publisher=fedoralegacy.org|access-date=2008-03-02|url-status=dead|archive-url=https://web.archive.org/web/20130905040726/http://www.fedoralegacy.org/|archive-date=2013-09-05}}</ref>
 
==Features==
Version 3.0.3 was one of the first Linux distributions to support [[Executable and Linkable Format|ELF]] (Executable and Linkable Format) binaries instead of the older [[a.out]] format.<ref>[http://www.linuxjournal.com/article/139 Linux Distributions Compared], Linux Journal, 1996</ref>
 
Red Hat Linux introduced a graphical installer called [[Anaconda (installer)|Anaconda]] developed by Ketan Bagal, intended to be easy to use for novices, and which has since been adopted by some other Linux distributions. It also introduced a built-in tool called ''Lokkit'' for configuring the [[firewall (networking)|firewall]] capabilities.
 
In version 6 Red Hat moved to [[GNU C Library|glibc]] 2.1, [[Enhanced GNU Compiler System|egcs-1.2]], and to the 2.2 kernel.<ref name = "smoogespace"></ref> It was the first version to use the [[GNOME]] as its default graphical environment.<ref>{{cite web |url=https://www.linuxjournal.com/article/3590 |title=Red Hat Linux 6.0 |last=Kroll |first=Jason |date=September 1, 1999 |publisher=[[Linux Journal]] |access-date=April 14, 2023}}</ref> It also introduced [[Kudzu (computer daemon)|Kudzu]], a software library for automatic discovery and configuration of hardware.<ref>{{cite web|url=http://everything2.com/title/kudzu |title=Various Kudzu facts |publisher=Everything2.com |access-date=2013-05-05}}</ref>
 
Version 7 was released in preparation for the 2.4 kernel, although the first release still used the stable 2.2 kernel. Glibc was updated to version 2.1.92, which was a beta of the upcoming version 2.2 and Red Hat used a patched version of GCC from CVS that they called "2.96".<ref>{{cite web|url=https://lwn.net/2000/1005/dists.php3 |title=Distributions |publisher=LWN |access-date=2013-05-05}}</ref> The decision to ship an unstable GCC version was due to GCC 2.95's bad performance on non-i386 platforms, especially [[DEC Alpha]].<ref>{{cite web|url=https://lwn.net/2000/1005/a/rh-tools.php3 |title=a/rh-tools |publisher=Lwn.net |access-date=2013-05-05}}</ref> Newer GCCs had also improved support for the [[C++]] standard, which caused much of the existing code not to compile.

Release dates were drawn from announcements on ''comp.os.linux.announce''. Version names are chosen as to be cognitively related to the prior release, yet not related in the same way as the release before that.<ref name = "smoogespace"></ref><ref>[http://fedoraproject.org/wiki/History_of_Red_Hat_Linux History of Red Hat Linux] - Fedora wiki</ref>
 
The Fedora and Red Hat Projects were merged on September 22, 2003.<ref>{{cite web|title= Fedora and Red Hat to Merge|url=http://www.linuxjournal.com/article/7169|access-date=2008-08-02}}</ref>
