The Bourne Shell is a Unix shell upon which many shells are based; notably the Korn shell and Bourne Again SHell. (The other major tree of Unix shells descend from csh.)
Portable Shell Syntax is the scripting language syntax used by the System V Bourne shell. This syntax is compatible with the heirloom shell and is the syntax documented in most Unix books. Examples marked "Works with: Bourne Shell" should work in any of the Bourne-compatible shells.
A Bourne Shell script begins with a shebang (also known as a hashbang) like this, which tells the operating system to use the Bourne compatible shell interpreter:
#!/bin/sh
In 2009, Computerworld published an in-depth interview with Steve Bourne, The A-Z of Programming Languages: Bourne shell, or sh, which details the Bourne shell origins and design decisions.
