# Script: MiniFetch
# Author: ThinkRoot
# Version: 4.1

# Description:
#   MiniFetch is an interactive Bash script that provides detailed information about the operating system it runs on.
#   It displays information such as the username and hostname, operating system and kernel version, system architecture, uptime, total number of installed packages, available and used storage space, memory usage, and processor information. Users can use this script for system troubleshooting and administration.

# Usage:
# 1. Open the terminal and navigate to the directory where you saved the script.
# 2. Grant execution permissions to the script using the command: chmod +x MiniFetch.sh.
# 3. Run the script without arguments to display standard information or run with the "-a" argument to display all information.
