Shell Command To Find What Linux Kernel Version Have Installed In Unix Box

Posted On Sat Jan 13, 2007 By pinguin In Linux wallpaper Hosting forums topics about gallery sites in linux systems Forums

today i wanted to find out what kernel version i had installed in my server, i can't believe i cound remember the command to find what version i had installed in my server linux box, but i found it, so just in case anyone outhere is also having the same question i will give you the command.

note, this worked for me, i have fedora core on my server, which i think will also work on red had, centos, but not sure if it will work on other distributions like suse, mandrake or Debian.

CODE:

rpm -qa | grep 'kernel'

here are some others, but the one above worked great for me

CODE:

$ rpm -q kernel kernel-headers kernel-ibcs kernel-pcmcia-cs kernel-source

kernel-2.0.36-0.7
kernel-headers-2.0.36-0.7
kernel-ibcs-2.0.36-0.7
kernel-pcmcia-cs-2.0.36-0.7
kernel-source-2.0.36-0.7

$ rpm -q mkinitrd SysVinit initscripts

mkinitrd-1.8-3
SysVinit-2.74-5
initscripts-3.78-1

If you have Red Hat Linux 4.2 on your machine, you will need to change the query slightly to reflect name changes in packages that occurred in the Red Hat Linux 5.x series of releases.

CODE:

$ rpm -q kernel kernel-headers kernel-source iBCS pcmcia-cs

kernel-2.0.35-0
kernel-headers-2.0.35-0
kernel-modules-2.0.35-0
kernel-source-2.0.35-0
iBCS-2.0-8
pcmcia-cs-2.9.12-0

$ rpm -q mkinitrd SysVinit initscripts

mkinitrd-1.7-1
initscripts-2.96-1
SysVinit-2.64-8

you can also use the uname command like this:

CODE:

uname -r

       uname - print system information
