Bash (Bourne Again Shell)

Bash, short for "Bourne Again Shell," is a command-line interface and scripting language used in many operating systems, particularly Linux and macOS. It allows users to interact with their computer by typing commands, which can perform tasks like file management, running programs, and automating repetitive actions through scripts. Bash is powerful and versatile, enabling users to execute complex sequences of commands easily. Its name reflects its origins from an earlier shell called Bourne Shell, and it has become popular due to its efficiency and scripting capabilities in both personal and professional computing environments.
