#!/bin/bash
USERNAME="Your_user_name"

# Create user and add to sudo group
  useradd  --create-home -s /bin/bash $USERNAME
  sudo usermod -aG sudo $USERNAME 

#Create ssh directory and lock password login
  mkdir /home/$USERNAME /home/$USERNAME/.ssh
  chown $USERNAME.$USERNAME /home/$USERNAME /home/$USERNAME/.ssh 
  passwd -l $USERNAME 


passwd -l $USERNAME // for disabling password login
passwd -u $USERNAME // will unlock account if needed
