supersleep - Enhanced sleep with progress tracking

A drop-in replacement for sleep with real-time progress output and accurate timing. Perfect for long-running sleeps where you want to check progress without starting over.

Features

• Accurate timing - Uses elapsed time tracking to prevent drift, even for very long sleeps
• Two output modes - Text countdown or visual progress bar
• Interactive ctrl-c handling:
  • First ctrl-c: Shows time remaining without exiting
  • Second ctrl-c within 2 seconds: Gracefully exits the sleep
• Multiple time formats - Support for seconds (s), minutes (m), hours (h), and days (d)
• Fast refresh rate - 2-second update intervals for responsive feedback

Installation

go build

Usage

./supersleep TIME [OPTIONS]

Time Format

• 30s - 30 seconds
• 5m - 5 minutes
• 2h - 2 hours
• 1d - 1 day
• Plain number - interpreted as seconds

Options

• -t - Text mode (shows time remaining in seconds)
• -b - Bar mode (shows progress bar with percentage)
• (default) - Progress bar mode if no option specified

Examples

# Sleep for 14 minutes with text countdown

Interactive Commands

While sleeping, press:

• Ctrl-C (once) - Display time remaining and continue
• Ctrl-C (twice within 2 seconds) - Exit immediately

Improvements Made (v2)

• Fixed time drift issues with elapsed-time based tracking instead of fixed intervals
• Added interactive ctrl-c signal handling for displaying time remaining
• Cleaner code structure and error handling
