linux

When creating dev and staging environments based on an existing production environment (I know, right) it is useful to get the version of Linux you are running. In Ububntu, just fire up your terminal and type:

lsb_release -a

This will output something similar to:

Distributor ID: Ubuntu
Description:    Ubuntu 9.10
Release:        9.10
Codename:       karmic

Woot.
