Can you explain what Bash is and what it is used for?

Bash (Bourne Again SHell) is a command-line shell and scripting language widely used in Unix-like operating systems. It allows users to interact with the system through the command line, run programs, manage files, and automate tasks with scripts.

Main uses of Bash:

• Executing commands and managing files in the terminal.
• Automating routine tasks with scripts.
• Configuring the user environment.
• Managing processes and system resources.

Example of a simple Bash script that lists files in the current directory:

#!/bin/bash
for file in *; do
  echo "$file"
done

Thus, Bash is a powerful tool for administration and automation in Linux and macOS systems.
