I want you to think about what terminal shell you use, if you haven’t changed it, it is most likely that you use Bash. While Bash is the one that most Linux distro’s use, there are may other shells that have their own unique features. For the purposes of testing, I used 5 different shells, and I am going to give a review of the Bash, Fish, Zsh, Dash, and Ksh Shells.
I believe the original Almquist shell is used on FreeBSD. I know on Debian dash is the sh implementation (afterall it is Debian Almquist Shell), but the default login shell for the root user is bash apparently.
/bin/sh historically used to be an actual shell(the Bourne shell*), but now by default it points to one set by the distro’s devs. Almquist shell was an alternative developed with a BSD license and i guess its still used
/bin/sh is just a symlink to the default shell which usually is dash for root on linux
