adduser
Create a new user
What it does
adduser creates a user along with a home folder /home/<name> and a group of the same name, then asks step by step for a password and details such as the full name; you can skip those with Enter. It needs sudo.
This is a friendly wrapper from Ubuntu and Debian. The low-level useradd exists everywhere, but without -m it creates no home folder and it does not ask for a password. Users are removed with deluser.
Syntax
sudo adduser <user>
sudo deluser <user>Examples
Create the user deploy with a home folder
sudo adduser deployadduser— create a user; asks for a password and detailsdeploy— the new user's name
