How to find kernel version in Ubuntu 12.04 Precise Pangolin

Note: This also works in other versions of Ubuntu, such as 11.10, 11.04, 10.10, 10.04 and earlier.   Sometimes you may wish to find out which kernel you’re  currently running; fortunately, this is quite easy to do with the uname command. If you’re running Ubuntu Desktop, open up a Terminal; if you’re using Ubuntu Server log in as per usual and then run:  

uname -v

…for the kernel version, or:  

uname -r

for the kernel release. You can combine the two and use:  

uname -rv

to see both of those with the one command.
