Create the user account
First,. create the user account using the standard Linux/UNIX useradd command:
NEWUSER='newusername'
SSHPUBKEY='ssh-ed25519 AAAA..xyz jamieson@desktop'
sudo useradd -m $NEWUSER
Add the SSH public key to that user's authorized_keys file
It's critical to chown the directory back to the user, or the SSH command will reject the modified file.
sudo mkdir /home/$NEWUSER/.ssh/
echo "$SSHPUBKEY" | sudo tee -a /home/$NEWUSER/.ssh/authorized_keys >/dev/null
sudo chown -R $NEWUSER:$NEWUSER /home/$NEWUSER/.ssh
Set up sudo permissions for that user
This uses the standard /etc/sudoers.d directory (found in all major distributions) to add sudo permissions with an "ALL" role to the user account.
echo "$NEWUSER ALL=(ALL) NOPASSWD: ALL" | sudo tee "/etc/sudoers.d/$NEWUSER" >/dev/null
(Disclaimer: I wrote the first release of a tool that automates this at Userify.)
