Bash (the Bourne Again SHell) was created by Brian Fox for the GNU Project in 1989 as a free replacement for the Bourne Shell (sh), incorporating features from the Bourne Shell, KornShell (ksh), and C shell (csh). The aim was to provide a powerful scripting and interactive shell compatible with POSIX while adding user-friendly features like command-line editing, job control, and improved scripting constructs. Bash became widely adopted because it was included in many Unix-like systems and later became the default shell on many Linux distributions. Sharing history on the forum helps learners appreciate design trade-offs and why certain legacy behaviors persist in modern scripts.
