introduction

Most of us need to create users accounts once in a while. System administrators frequently work
with user accounts on a daily basis. The following text wants to explain how to work with (create,
modify) user accounts and groups in a Linux environment.
Most of the people never bothered to understand this or they run into complicated documentation
that doesn’t clarify things. I will try to make this as comprehensive as possible, but in the end,
you’ll be the one to judge.
