Finding Version of Redhat

Kyle D. Harris — Fri, 15 Aug 2003 13:54:11 GMT

I have about 4 Linux Boxes and some have different versions of RedHat. Can anybody tell me a command or something that i can type in to see what version is on a particular Redhat Box? I'd like to try not to have to reboot. Thanks Alot in advance!!!

Kyle,
If you are looking for kernel version then check with uname -r.
If for RH releases then use cat /etc/issue. If my memory is correct, then in most of the Releases it gives the release.

HTH,

One method is:
on the command line:
grep running /etc/sysconfig/rhn/systemid

Also look at /etc/redhat-release.

Umapathy-
i got this back with the uname -r :
2.2.22-6.2.3

Does this mean i have Redhate 6.2? i'm not sure what the 2.2.22 or the .3 after 6.2 is for?.... Thanks

Hi Kyle,

2.2.22-6.2.3 is your kernel release

Redhat adds its own kernel release on top of official releases, you run kernel 2.2.22, and redhat release of this kernel is numbered 6.2.3...

cat /etc/redhat-release works if you are root on the system.

.../rhn/systemid works if you use rhn...

Thanks guys, That worked. Didn't know you had to be root to do that command. Appreciate it greatly!

You don't. The 'redhat-release' file usually has permissions of root:root, 0644 (i.e. readable by everybody, only writable by root).
