QuickPost: What version of Ubuntu am I running?
lsb_release TO DISPLAY THE RUNNING UBUNTU VERSION
This is a QuickPost™ (not really trademarked), and I’ll get to the point. To find out what version of Ubuntu a system is running use the command
lsb_release. This isn’t something you’ll need everyday, but when you do it’s good to know.
There several options when running
lsb_release, but the two you’re most likely to find useful are
lsb_release -a - show everything, and
lsb_release -r - show only the release.
root@ubuntu:~# lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 16.10 Release: 16.10 Codename: yakkety root@ubuntu:~#
root@ubuntu:~# lsb_release -r Release: 16.10
There’s not much else to say. You could look at some system files and extrapolate the version from there, but why do that when one command can give you everything you need?
The manpage is short so I’ve posed the majority of it below.
