hello ,

Can anybody tell me what is the difference between Redhat Linux and Redhat Enterprise Linux (RHEL) . actually i want to know why the term " Enterprise" is used here ?

thanks..

Redhat Linux does not exist anymore it was replaced by Fedora Core and Redhat Enterprise Linux. The Enterprise part means that the distro is specifically designed to run in "enterprise class" environments e.g. on corporate servers, multi processor systems, etc. It has features such as clustering, advanced remote management, selinux, scalability etc. This also means that it costs more because its bundled with various support options that a normal user may not need but which could be essential for big businesses.

So far as I understand RHEL is like a corporate product which is supported by Redhat, it's the support you're paying for.

thanks all for making me understand it clearly

There is another issue with the enterprise class systems: It is the related with the time frame a security related patch is available. In the Enterprise class, the vendor provides that security fix. You always can expect a fix from the vendor, not from community.
Another issue is Enterprise versions are more stable, I mean, there is no updates/upgrades expect if they are related to security. Its mean less overload in the administrating a enterprise OS, since new versions of several programs are left to a major upgrade in next version. Any updates are tested very carefull to avoid any disruption in the system.
At the last there is a well defined and long period for the time life of product. You know in advance how many years the vendor will support the version you are buying right now.

cheers,

To all,
My man pages has problem. Example as shown...

WHY????

Han Tin, you should open your own thread for this issue; you're posting off-topic here. - Be as specific as possible, i.e., what's your Linux distribution, does this problem occur with one man page only, or with any, do you experience text encoding issues with other applications than man pages, what's the language your system is translated to, etc.

thanks reddazz amd marozsas for ans on diffrence between red hat linux and rhel?

just to clarify, there is ZERO cost for RHEL(RedHat Enterprise Linux), what you are paying for is the SLA for the phone/email/onsite support over X amount of time for Y amount of Licensed servers.

you can get RHEL for free, but will have limited if any updates unless you pay for the SLA.

otherwise use a free, as in beer, fork of RHEL like CentOS and Scientific Linux.

RedHat Linux was replaced over a decade ago by Fedora Core (RedHat Linux 9 was the last release) today Fedora core is just Fedora and is on release 19 with 20 going public beta by the end of the year.

The Company RedHat made the choice to SELL their SERVICE, support, updates, customized patches, LONG term support up to 10 and even 15 years if you pay for it, etc... and to produce a community driven "desktop" flavor of their OS called Fedora.

Fedora is the leading kernel/devel/GUI/etc... of RHEL. To provide a specific example Fedora 19/20 is what RHEL v7 will be based on from a kernel and systemd standpoint.
