Hi, it’s simple. You can find out the version details simply from the command line. Here I am explaining the ways to find out the version of OS in your server/system.

Method I
You may use the “lsb_release” along with the switch “a”, see the example below:

# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 12.04 LTS
Release:        12.04
Codename:       precise

Method II
The version details are aslo stored in the “/etc/issue” file, you may also cat this file, see the example below;

# cat /etc/issue
Ubuntu 12.04 LTS \n \l

That’s it. 🙂
