BASH SHELL

Bash shell (also known as the Bourne-Again SHell) is a command-line interface (CLI) for interacting with your computer's operating system.

Think of it like a messenger between you and your computer's brain (the OS). You give commands, and Bash executes them.

Here's what Bash does:

  1. Reads commands: You type commands, and Bash reads them.
  2. Interprets commands: Bash figures out what you want to do.
  3. Executes commands: Bash tells the OS to perform the actions.

Bash is:

  • A shell: A program that surrounds the OS, allowing you to interact with it.
  • A command-line interface: You type commands, and Bash responds.
  • A scripting language: You can write scripts (like recipes) for Bash to execute.

Bash is widely used in:

  • Linux
  • macOS
  • Unix
  • Windows (with Windows Subsystem for Linux)

Some common Bash features include:

  • Running programs
  • Managing files and folders
  • Customizing settings
  • Automating tasks with scripts

Bash is powerful, flexible, and a fundamental tool for developers, sysadmins, and power users!
