Before you create a new user account, there's a few user account properties that you need to know:
- usernma
- password - in /etc/shodow, if it shows "!!" then it means that account doesn't have a password yet. You fix this by running the "passwd username" command as the root user
- uid
- guid - full list of guids are available in /etc/groups file
- home directory
- group name - a primary group is created at the same time as the user account, and it is named after the user account's username
- GECOS - a description for the user.
- home directory
- default shell
