* Major Differences from the Bourne Shell
Major differences between
Bash and the Bourne shell.


   Bash implements essentially the same grammar, parameter and variable
expansion, redirection, and quoting as the Bourne Shell.  Bash uses the
Posix 1003.2 standard as the specification of how these features are to
be implemented.  There are some differences between the traditional
Bourne shell and the Posix standard; this section quickly details the
differences of significance.  A number of these differences are
explained in greater depth in subsequent sections.
