Change shell for a user:
========================
Before hand list the shell you want is already installed by using this command:
cat /etc/shells

To change the shell of your user, run this command:
sudo usermod --shell /bin/bash myuser
*Replace myuser with the wanted user name.

You will then need to log out of that user and log back in for it to take affect.
