How to Find Linux Kernel Version

To find information about current running Linux kernel execute the command uname. The most important options are:
  • uname -a Print all information about the Linux OS.
  • uname -o Print the name of the OS.
  • uname -r Print Kernel release information.
  • uname -v Print the version of the Kernel.

Example

[leon@localhost ~]$ uname -a
Linux localhost.localdomain 2.6.30.9-96.fc11.i586 #1 SMP Tue Nov 3 23:33:04 EST 2009 i686 i686 i386 GNU/Linu

How to Find All Installed Kernel Versions
