How to check which Ubuntu release is installed (including codename)
If you are not sure which Ubuntu version you are currently using or you need its codename, open a terminal and run the following command:
lsb_release -drc
This should give you something like
user@host.local:~$ lsb_release -drc Description: Ubuntu 9.10 Release: 9.10 Codename: karmic
You may find the -s
parameter useful if you need the pure codename or release number (e.g. for doing comparisons within a bash script). Examples:
user@host.local:~$ lsb_release -sc karmic user@host.local:~$ lsb_release -sr 9.10
Have a look at the lsb_release manpage to get a list of all available parameters.
