Bourne shell : ウィキペディア英語版 | Bourne shell
The Bourne shell (sh) is a shell, or command-line interpreter, for computer operating systems. The Bourne shell was the default Unix shell of Unix Version 7. Most 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 1977 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. ==History==
