Its also worth taking a look in /etc/passwd for listing of users.

adduser blah userdel blah

groupadd users //Create a Group adduser username users //Add a Member into the above group (Not making it their primary group)

//Putting a user into a group manually. This will not make it their primary group! vi /etc/group adm:x:4:user1,user2

Make the newgroup the PRIMARY one for the user:<br> Particularly useful, as adding a user into a group will not change their primary group!! usermod -g newgroup user

//This is what should be normally done, as it makes users their PRIMARY group, instead of making a new one!! adduser –ingroup users username

//dont know if this is essential, but add them into the groups file in /etc - adduser username users

Instead of editing manually /etc/group, this is the preferred way: adduser username group
