How To Find Your Ubuntu or Kernel Version

Method to find your version is a command line method. There are two commands you can use:

cat /etc/issue

or you can use

cat /etc/lsb-release

…and finally to find your kernel version and a few more details about your machine use the uname command which, per the man pages, shows system information. Examples:

uname -a : print all information

uname -r : print the kernel release

uname -v : print the kernel version

uname -o : print the operating system

see man uname for more details on using the uname… and now you should be able to find out more about your machine, report better bugs and continue to make Ubuntu even better!
