/bin/sh is dash

That all depends on the OS. That appears to be true for Debian and Debian-based OSes (Ubuntu, ArchLinux, etc). On Fedora 25 /bin/sh is a symbolic link to bash. On some OSes /bin/sh is still the Bourne shell.

On some OSes `/bin/sh` is still the Bourne shell. And that's not all. `/bin/sh` varies wildly with OS and OS version, so it should be avoided where possible. If one has to resort to using a shell (why on earth?), one should explicitly use that shell (e.g. use `/bin/bash`, `/bin/ksh` or the like) instead of hoping for the default shell.
