Create a sudo user in script with no prompt for password, change to user without interrupting script

问题

This is what I'm trying to do in a script. It works here manually, but prompts me for a password. How do I:

1. Create a new user
2. With sudo privs
3. Switch to that user

4. Continue executing the rest of the script

   sudo adduser centos
   sudo passwd centos
   usermod -aG wheel centos
   sudo su centos
   

I have tried the following but in Centos 7 bash, --disabled-password and -gecos both say "option not found."

adduser --disabled-password --gecos "" username

You don't need sudo su centos because your script would be interrupted by a terminal. If the following commands are actually "./install.sh" (like) that have to be started by "centos" user, then you can do the following modification:

sudo adduser centos
sudo passwd centos
usermod -aG wheel centos
sudo su - centos -c ./install.sh
sudo su - centos -c ./install_another.sh

sudo su - centos -c "./install_more.sh ; cd /tmp ; ./install_almostlast.sh"

sudo su - centos -c bash -c "cd /somewhere; ./install_more.sh
        cp /tmp/files /somewhere
        ./install_last.sh
        rm /tmp/install.sh"

Between double quotes you can write a whole script if you want and are careful of the content and quoting.
