Basic OS question

Could someone tell me the command to find out the OS version which will give 12 character not the 9 characters(which is usually machine id).
uname -i gives machine id and uname -a is more comprehensive way to look.
Thanks!

I think you want

uname -srv

Thanks jim mcnamara
Not sure I'm looking for that.

We'll be more than happy to help.
Could you give a bit more detail as to what information you need?

Sorry for confusion, I figured it out.
