  • sh: the basics, POSIX standard
  • ash: reimplementation of sh
  • dash: port of ash
  • ksh: extensions on top of sh
  • bash: massive extensions on top of sh (mostly a superset of ksh's)
  • zsh: massive extensions on top of sh but different ones to bash

  • csh: a completely different shell to sh, contemporary in origin, mostly different syntax

  • tcsh: extensions on top of csh

  • fish: a completely different shell again, cut-down syntax and features mostly targeted at interactive users

So, yeah, it's important to specify which shell you're targeting.
