BASH
Strap in for a thrill ride! short for the Bourne-Again Shell, is the GNU Project’s Unix shell and command language that was originally released in 1989 by Chet Ramey. It was the free software replacement for the Version 7 Unix shell (sh) released in 1977. This suspended the shell used with Version 4 Unix in 1973, which itself was a replacementshell (sh) that was written by Ken Thompson himself for the original 1971 Unix.
