There are lots of commands to find out your ditribution name and distribution version. Some work on some distros, some work on others. Here are some of the methods:

• lsb_release -a

• cat /etc/*release

• cat /etc/issue

• cat /proc/version

• uname -a

One of these methods will surely tell you your linux distribution name and current version.

Cheers!
