How to display the version of you linux kernel


 * 1) Here are a couple of ways of determining which versions of the kernel you have:

uname
uname potentially provides the following information on the operating system: Usage: uname [OPTION]... Print certain system information. With no OPTION, same as -s. -a, --all               print all information, in the following order, except omit -p and -i if unknown: -s, --kernel-name       print the kernel name -n, --nodename          print the network node hostname -r, --kernel-release    print the kernel release -v, --kernel-version    print the kernel version -m, --machine           print the machine hardware name -p, --processor         print the processor type or "unknown" -i, --hardware-platform print the hardware platform or "unknown" -o, --operating-system  print the operating system the output for uname -a is all one one long line, so it can be hard to decipher when one part ends and another begins. It is likely more useful to use the options one at a time. i686 i686 GNU/Linux Linux 2.6.18-128.el5xen
