ssysi (Small System Information)

ssysi is a simplified, lightweight system information tool. The goal of this project is to provide essential system information in a minimal package, under 10KB, while retaining useful and practical features for everyday system monitoring.

Key Features

• Minimalist Design: Under 10KB in size, making it fast and resource-efficient.
• Essential System Stats:
  • CPU model, core count, and thread count.
  • Memory usage and swap statistics.
  • Disk usage and mounted drives.
  • System uptime and kernel information.
  • Battery status (if applicable).
• User-Friendly Output: Information is presented in a clean, formatted, and color-coded way to improve readability.
• Lightweight & Fast: No unnecessary overhead, designed for speed and low resource usage.
• Terminal-Friendly: Runs seamlessly in the terminal, with centered text for a polished look.

Displayed Information

1. System Information:

   • OS, hostname, model
   • Kernel version, uptime
   • Screen resolution

2. CPU Information:

   • Model name, core count, and thread count

3. Memory & Swap Usage:

   • Memory and swap usage percentages

4. Disk Usage & I/O Statistics:

   • Disk usage for root (/)
   • Mounted drives and their usage
   • I/O stats (read/write speeds)

5. Battery Status (optional):

   • Current charge and state

6. Top Processes:

   • Processes ranked by CPU and memory usage

How It Works

• Color Formatting: Uses ANSI escape codes for background colors and clear text presentation.
• Centered Text: Outputs all information neatly centered in the terminal for readability.
• Efficient Parsing: Uses lightweight commands like awk, ps, df, and free for data collection.

Example Usage

Running the script will display a concise overview of your system's current state, such as:
