For my cluster project I will add a new user to each Raspberry Pi. This is so the user I use for all other systems will be the same on the Raspberry Pi’s. This post describes how to add another user to Raspbian OS.
Adding a new user to Raspbian OS
To add a user to your Raspberry Pi running Raspbian OS you can run the following command. You should replace
chewett with your desired username.
sudo adduser chewett
Once this has been run you will be presented with a number of dialogue options. The most important one is asking for your password. The other information can be useful where there are a number of users on a system however for a Raspberry Pi this likely isn’t too important.
pi@bunker-speedtest:~$ sudo adduser chewett
Adding user `chewett' ...
Adding new group `chewett' (1001) ...
Adding new user `chewett' (1001) with group `chewett' ...

Changing the user information for chewett
Enter the new value, or press ENTER for the default

Is the information correct? [Y/n] y
Once you have confirmed all this information the user will be created. At this point you might want to add the user to any groups you have created. If you want to want to use the vcgencmd command to read temperature or other system information you will need to add them to the video group.
