Brian J. Fox
, the Free Software Foundation's first paid programmer, started working on a shell in 1988. This became Bash
, first released as a beta in 1989. Bash is distributed widely as the default login shell for most Linux distributions and Apple's macOS (formerly OS X). Bash is a clone of the Bourne shell (hence "Bourne-Again"), but it also includes additional features inspired by the C shell
and Korn shell
. Brian Fox was the official maintainer of Bash until 1992. At the time, Chet Ramey already was involved with the work on Bash, and he became the official maintainer in 1993. And he's still Bash's current maintainer.
