In this post I am going to discuss how to add new users to Raspberry Pi and why you want to.
Users and usergroups are important even if you are a super user. Run the wrong application or script as an incorrect user and things can get bad really fast depending on the script (or you can think giving a young person root access). User groups are there to save us from our self. I have a few scripts I run that have to run that ask before you start if you sure you want to run as root user group. So in this short tutorial I am going to show you how to add a user and give the needed user group permissions.
Adding a user
Adding new users to raspberry pi is easy, just run
sudo adduser newuser
This command will add a /home/newuser folder and create a new group “newuser”
If you ever need to edit the password fo newuser just use the command:
sudo passwd newuser
If you want to really dig into the adduser run the following
Give user permissions
I am sure you would like the user to be able to have some permissions lets give them the basics
sudo adduser newuser dialout,audio,video,games,users
Also, you can run
usermod -G all,existing,groups,except,for,group newuser
need to remove the permissions just as easy as adding them
sudo deluser newuser root
