Bash

Bash, short for “Bourne Again Shell,” is a powerful Unix shell and command language commonly used on Linux and macOS systems. As a command processor, Bash executes commands read from the user input or from files, offering a robust environment for managing files, running scripts, and automating tasks. It is an enhanced version of the original Unix shell (sh) developed by Stephen Bourne, featuring improvements such as command-line editing, job control, and shell functions, making it a preferred choice for system administrators and developers alike. Bash provides a scripting environment where users can write scripts to automate repetitive tasks, manage system configurations, and perform complex operations. Its syntax and built-in features enable efficient manipulation of text files, directories, and processes, solidifying its status as a foundational tool in the Unix ecosystem.
