Bourne shell         
(sh, Shellish). The original command-line interpreter shell and script language for Unix written by S.R. Bourne of Bell Laboratories in 1978. sh has been superseded for interactive use by the Berkeley C shell, csh but still widely used for writing shell scripts. There were even earlier shells, see glob. [Details?] ash is a Bourne Shell clone. ["Unix Time-Sharing System: The Unix Shell", S.R. Bourne, Bell Sys Tech J 57(6):1971-1990 (Jul 1978)].

Bash is a Unix shell and command language written by Brian Fox for the GNU Project as a free software replacement for the Bourne shell. First released in 1989, it has been used as the default login shell for most Linux distributions. Bash was one of the first programs Linus Torvalds ported to Linux, alongside GCC. A version is also available for Windows 10 and Windows 11 via the Windows Subsystem for Linux. It is also the default user shell in Solaris 11. Bash was also the default shell in versions of Apple macOS from 10.3 (originally, the default shell was tcsh) to the 2019 release of macOS Catalina, which changed the default shell to zsh, although Bash remains available as an alternative shell.

Bash is a command processor that typically runs in a text window where the user types commands that cause actions. Bash can also read and execute commands from a file, called a shell script. Like most Unix shells, it supports filename globbing (wildcard matching), piping, here documents, command substitution, variables, and control structures for condition-testing and iteration. The keywords, syntax, dynamically scoped variables and other basic features of the language are all copied from sh. Other features, e.g., history, are copied from csh and ksh. Bash is a POSIX-compliant shell, but with a number of extensions.

The shell's name is an acronym for Bourne Again Shell, a pun on the name of the Bourne shell that it replaces and the notion of being "born again".

A security hole in Bash dating from version 1.03 (August 1989), dubbed Shellshock, was discovered in early September 2014 and quickly led to a range of attacks across the Internet. Patches to fix the bugs were made available soon after the bugs were identified.

Aleck Bourne         
BRITISH GYNAECOLOGIST AND PRO-LIFE ACTIVIST (1886-1974)
Alec Bourne; Aleck William Bourne
Aleck William Bourne (4 June 1886 – 30 December 1974) was a prominent British gynaecologist and writer, known for his 1938 trial, a landmark case, in which he was prosecuted for performing a termination of pregnancy on a 14-year-old rape victim. He was subsequently charged with procuring an illegal abortion but was acquitted.

Bourne shell

The Bourne shell (sh) is a shell command-line interpreter for computer operating systems.

The Bourne shell was the default shell for Version 7 Unix. Unix-like systems continue to have /bin/sh—which will be the Bourne shell, or a symbolic link or hard link to a compatible shell—even when other shells are used by most users.

Developed by Stephen Bourne at Bell Labs, it was a replacement for the Thompson shell, whose executable file had the same name—sh. It was released in 1979 in the Version 7 Unix release distributed to colleges and universities. Although it is used as an interactive command interpreter, it was also intended as a scripting language and contains most of the features that are commonly considered to produce structured programs.

It gained popularity with the publication of The Unix Programming Environment by Brian Kernighan and Rob Pike—the first commercially published book that presented the shell as a programming language in a tutorial form.
