Terminal System Monitor TUI
An interactive terminal dashboard built with ANSI escape codes that shows live-updating CPU, memory, disk, and network stats in a multi-panel text UI, with keyboard navigation between panels. Learners practice ANSI escape sequences, screen refresh loops, and building interactive TUIs without external languages.

Project roadmap
- 01
Build the data-gathering functions
~2hReuse /proc parsing functions for CPU, memory, disk, and network throughput sampled at an interval.
- 02
Design the multi-panel layout with ANSI codes
~2.5hUse cursor positioning escape codes to draw fixed panels for each metric without flickering on refresh.
- 03
Implement the refresh loop
~2hBuild a loop that redraws only changed regions at a configurable interval (e.g. every 2 seconds).
- 04
Add keyboard navigation
~2.5hRead single keypresses non-blockingly to let users switch between a summary view and a detailed process view.
- 05
Add color-coded thresholds
~1.5hColor metrics red/yellow/green based on configurable warning thresholds.
- 06
Handle terminal resize gracefully
~1.5hTrap SIGWINCH to recompute panel layout when the terminal window is resized.
