What’s the difference between sh, bash and zsh
sh
(or the Shell Command Language) is a programming language described by the POSIX standard.
bash
contains many more features including those of sh
. Sometimes sh
is symlinked to bash
zsh
(or the Z Shell) is like bash
on steroids, slightly (word-splitting) incompatible with bash
. If you are going this route, check out http://ohmyz.sh/
