Learn Bash (Shell)

Bash, short for "Bourne Again Shell," is a command-line interpreter or shell program for Unix-like operating systems. It is the default shell on most Linux distributions and macOS. Bash is an enhanced version of the original Unix shell written by Stephen Bourne.
As a shell, Bash provides a command-line interface (CLI) for users to interact with the operating system by typing commands. It acts as a command processor, interpreting and executing commands entered by the user or scripts.
Bash is highly versatile and powerful, making it a fundamental tool for system administrators, developers, and power users working on Unix-like systems. It provides a flexible and efficient environment for managing and interacting with the operating system via the command line.
