   dash is meant to be a more strict and less feature-ridden   
   POSIX-compliant shell. It’s on Debian, too. So “/bin/sh” stopped   
   referring to bash years ago, and now uses dash instead.

       dash is the standard command interpreter for the system. The   
       current version of dash is in the process of being changed to   
       conform with the POSIX 1003.2 and 1003.2a specifications for the   
       shell. This version has many features which make it appear similar   
       in some respects to the Korn shell, but it is not a Korn shell   
       clone (see ksh(1)). Only features designated by POSIX, plus a few   
       Berkeley extensions, are being incorporated into this shell. This   
       man page is not intended to be a tutorial or a complete   
       specification of the shell.   
      
   If you want /bin/bash, you say /bin/bash.
