'''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 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 included 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 (computing)|firewall]] capabilities.

In version 6 Red Hat moved to [[glibc]] 2.1, [[Enhanced GNU Compiler System|egcs-1.2]], and to the 2.2 kernel.<ref name = "smoogespace"/> 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.

In particular, the use of a non-released version of GCC caused some criticism, e.g. from [[Linus Torvalds]]<ref>{{cite web|url=http://www.linuxtoday.com/news_story.php3?ltsn=2000-12-14-002-21-NW-RH-SW|archive-url=https://web.archive.org/web/20191222204453/https://www.linuxtoday.com/developer/2000121400221NWRHSW |archive-date=22 December 2019 |url-status=dead |title=Linus Weighs in on Red Hat 7 Compiler Issues |publisher=Linux Today |access-date=2013-05-05}}</ref> and the GCC Steering Committee;<ref>{{cite web|url=https://gcc.gnu.org/ml/gcc-announce/2000/msg00003.html |title=Gerald Pfeifer - GCC 2.96 |publisher=Gcc.gnu.org |date=2000-10-06 |access-date=2013-05-05}}</ref> Red Hat was forced to defend this decision.<ref>[http://features.slashdot.org/article.pl?sid=00/10/12/163218&mode=thread An Open Letter From Bob Young], Slashdot.org, Thu October 12, 2000 12:52 PM</ref>
GCC 2.96 failed to compile the Linux kernel, and some other software used in Red Hat, due to stricter checks. It also had an incompatible C++ [[Application binary interface|ABI]] with other compilers. The distribution included a previous version of GCC for compiling the kernel, called "kgcc".

As of Red Hat Linux 8.0, [[UTF-8]] was enabled as the default [[character encoding]] for the system. This had little effect on [[English language|English]]-speaking users, but enabled much easier [[Internationalization and localization|internationalisation]] and seamless support for multiple languages, including [[Ideogram|ideographic]], [[bi-directional text|bi-directional]] and [[Complex text layout|complex script]] languages along with [[Languages of Europe|European languages]]. However, this did cause some negative reactions among existing [[Western Europe]]an users, whose legacy [[ISO/IEC 8859|ISO-8859]]–based setups were broken by the change.{{Citation needed|date=February 2008}}

Version 8.0 was also the second to include the [[Bluecurve]] [[Theme (computing)|desktop theme]]. It used a common theme for GNOME-2 and KDE 3.0.2 desktops, as well as OpenOffice-1.0. KDE members did not appreciate the change, claiming that it was not in the best interests of KDE.<ref>{{cite web|url=https://www.theregister.co.uk/2002/09/17/red_hat_nullifies_kde_gnome/ |title=Red Hat nullifies KDE, Gnome |website=The Register |date=2002-09-17 |access-date=2014-02-14}}</ref>

Version 9 supported the [[Native POSIX Thread Library]], which was ported to the 2.4 series kernels by Red Hat.<ref>{{cite web|url=http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/release-notes/x86/ |title=Red Hat Linux 9 Release Notes |publisher=Redhat.com |access-date=2013-05-05}}</ref>

Red Hat Linux lacked many features due to possible [[copyright]] and [[patent]] problems. For example, [[MP3]] support was disabled in both [[Rhythmbox]] and [[XMMS]]; instead, Red Hat recommended using [[Vorbis|Ogg Vorbis]], which has no patents. MP3 support, however, could be installed afterwards, through the use of packages. Support for Microsoft's [[NTFS]] [[file system]] was also missing, but could be freely installed as well.

==Fedora Linux==
{{Main article|Fedora Linux}}

Red Hat Linux was originally developed exclusively inside Red Hat, with the only feedback from users coming through bug reports and contributions to the included software packages – not contributions to the distribution as such. This was changed in late 2003 when Red Hat Linux merged with the [[Virtual community|community]]-based [[Fedora Project]]. The new plan was to draw most of the codebase from Fedora Linux when creating new Red Hat Enterprise Linux distributions. Fedora Linux replaced the original Red Hat Linux download and retail version. The model is similar to the relationship between [[Netscape Communicator]] and [[Mozilla]], or [[StarOffice]] and [[OpenOffice.org]], although in this case the resulting commercial product was also fully [[free software]].

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>[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>
