Linux version and vi
 

As a RH user, I've seen people referring to RH version 9, version 7 and so on, but also, that RH is about to release RH version 5, as if it was the most recent version.
Question 1: RH version 9 and versions greather than 5 relate to what ?

Question 2: uname -r, gives me: "2.4.21-15.EL", as the Kernel release; is it related to a RH version 9 or 7 or another version of RH ?

Question 3: when I man vi, it describes comands for vim. where do I find a good doc for vi ?

Thanks.

Red Hat Versions
 

RH 5 is actually RHEL 5( Enterprise) not Redhat 5

1 - Redhat finished at version 9. it the split into Redhat Enterprise which started at 2.1, upto the latest 5.0 and fedora core, which started at 1 upto 7, due soon.

2 - 2.4.21 is the version of the linux kernel. see http://kernel.org. it is nothign to do wtih Redhat itself.

3 - depends what you want, i like the gentoo vi cheat sheet if you google for it.

For EdR
 

RH stands for Red Hat, right ?
E stands for Enterprise, right ?
L stands for what ?
How should I refer to the Linux I use ?

Thanks.

For Chris
 

1- So RH and RHE are different products, I mean, both are RedHat Linuxes but for different purposes, and when one refers to RH 9 he's talking about an older version than RHE(L?) 5, right ?

2- If the kernel version has nothing to do with Redhat version, a release of Redhat may have whatever kernel release?
(I didn't take a look at the page you suggested yet, so if the answer is there, never mind).

3- Thanks for the tip.

AC.

RHEL = Redhat Enterprise Linux

You can issue the command given below to find the version of Redhat you're using,

Thank you.
