Earlier, most of the software within the UNIX world was proprietary and closed source. UNIX was also not open-sourced that, you had to use a shell. There was a shell that existed at that point named "Bourne Shell" under the /bin/sh command which was proprietary and closed source. Bourne was named after its inventor- Steven Bourne.

Richard Stallman at that point began the GNU project with Free Software Foundation (FSF) to make a UNIX-compatible OS aiming everything as open-source. Progress was scarce within the revolution. He needed a free shell that would run existing shell scripts. it had been imperative to possess an open-source system built together of the few projects he funded with FSF. Then on January 110, 1988, Brian Fox (FSF employee) stated coding on Bash and published Bash as beta, variant 0.99 on June 8, 1989.

Brian Fox stayed in FSF as the primary Bash maintainer till the year 1993. Then he was laid faraway from FSF, and Chet Ramey (earlier contributor in FSF) got his responsibility.

More, on December 23, 1996, Chet Ramey issued a new bash variant 2.0 for the public with a kind of latest function over the old bash variant.

And now Chet Ramey is understood for being the official bash maintainer, and he continues to form further enhancements in bash.

Bash is that the standard shell included with Linux. it's the foremost popular shell known today for being open-source and with various productive features, we read within the further topic. it's available for Linux distributions, macOS, Solaris 11, and Windows 10 too. it's offering the simplest experience for its users with tons of improvements.
