In FreeBSD by default you do not have bash as shell prompt.
Here is the procedure to install it:
- type whereis bash
- cd to that folder
- type make configure
- make all install clean
- take a cofee 😉
- type chsh -s /usr/local/bin/bash root to change the shell for root or replace root with username you want to change the shell.
- Then relogin (logout and login) to enjoy bash shell
