System Information Script

Overview

This Bash script allows you to quickly gather system information such as disk usage, memory usage, and CPU-consuming processes. It comes with an easy-to-use interface that accepts command-line options to specify what information to display. The script also offers the ability to export the output to a file.

Features

• Show disk usage sorted by usage percentage in descending order.
• Display memory usage in a human-readable format.
• Show the top 10 CPU-consuming processes.
• Supports both short-form and long-form command-line options.
• Optional output redirection to a file.

Prerequisites

• Bash Shell Interpreter
• df, free, and ps utilities should be installed on the system.

Usage

Run the script using the following syntax:

./sys_info.sh [options] [output_file]

Options

• -d, --disk : Show disk usage, sorted by usage percentage.
• -m, --memory : Display memory usage in a human-readable format.
• -p, --process : Show the top 10 CPU-consuming processes.
• -h, --help : Display the help message and exit.

Output File

• output_file: Optional parameter specifying the file to which the output will be saved. If not provided, output will be displayed on the terminal.

To display disk usage sorted by usage percentage in descending order, use the following command:

./sys_info.sh -d

Display Memory Usage

To display memory usage in a human-readable format, use the following command:

./sys_info.sh -m
