Introduction

In the world of computers, there's a special tool called Bash. It helps people give commands to their computers and make them do things. Whether you're using a computer running on Linux, macOS, or something similar, Bash is there to help.

Getting to Know Bash: What It Is and Where It Came From

  • Bash is short for Bourne-again shell, which might sound complicated, but it's just a fancy way of saying it's a tool that lets you talk to your computer.
  • It was made in 1987 by someone named Brian Fox to replace an older tool called the Unix shell. Since then, it's become really popular because it's easy to use and does a lot of cool stuff.
