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.
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
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. 🙂
