How to find the version of ubuntu
cat /etc/lsb-release : This will give you the exact version, e.g. 9.10 & the name of the release. Btw, lsb means "Linux standard base"

32bit or 64 bits : getconf LONG_BIT

Add user : sudo useradd -d /home/testuser -m testuser
Here "testuser" is the name of the user being created.
Create a new group : groupadd mygroup
Here "mygroup" is the name of group being created
You can see the group by : less /etc/group
Add existing user to a group : useradd -a -G mygroup testuser
