The Bourne shell was once standard on all branded Unix systems, although historically BSD-based systems had many scripts written in csh. As the basis of POSIX sh syntax, Bourne shell scripts can typically be run with Bash or dash on Linux or other Unix-like systems; Bash itself is a free clone of Bourne.
Stephen Richard "Steve" Bourne (born 7 January 1944) is an English computer scientist based in the United States for most of his career. He is well known as the author of the Bourne shell ( sh ), which is the foundation for the standard command-line interfaces to Unix .
In computing, Bash (Bourne Again Shell) [7] is a Unix shell and command language first developed for the GNU Project [8] by Brian Fox, supported by the Free Software Foundation. [9] [10] Designed as a 100% [11] free software alternative for the Bourne shell, [12] [13] [14] it was initially released in 1989. [15]
The Bourne shell, sh, was a new Unix shell by Stephen Bourne at Bell Labs. [6] Distributed as the shell for UNIX Version 7 in 1979, it introduced the rest of the basic features considered common to all the later Unix shells, including here documents, command substitution, more generic variables and more extensive builtin control structures.
Bash, short for Bourne-Again SHell, is a shell program and command language supported by the Free Software Foundation [2] and first developed for the GNU Project [3] by Brian Fox. [4] Designed as a 100% [5] free software alternative for the Bourne shell, [6] [7] [8] it was initially released in 1989. [9]
The Unix System (ISBN 0-201-13791-7, ISBN 978-0201137910) is a book by Stephen R. Bourne. Published in 1982, it was the first widely available general introduction to the Unix operating system . It included some historical material on Unix, as well as material on using the system, editing, the software tools concept, C programming using the ...
These features could not overcome the shortcomings of the Thompson shell, and so a new shell was written from scratch by Stephen Bourne.This Bourne shell was incompatible with the Thompson and PWB shells, but included equivalents of most of the PWB shell's features, but done from scratch, rather than incrementally, with much discussion among the various participants.
It doubtless was ridiculously antique, poorly portable, and in K&R rather than ANSI C, but I'd be extremely surprised if it weren't the real Stephen Bourne codebase in all its 1970s (obsolete) glory -- and under Caldera's BSD-ish licensing terms. This history can be traced through the Heirloom Bourne Shell repository.
