Some random shell/python scripts

Created and intended for my personal use only. Some of these are ancient and most not well maintained, so if anyone stumbles upon this repo: Be warned, read/use at your own risk. :)

bedtime-shutdown.sh - 😴 Digital Detox: Bedtime Enforcer

If you find yourself doom-scrolling or debugging at 02:00 (2 AM), this script is your new best friend (or worst enemy). It forces a system shutdown at a set time every night to make sure you actually get some sleep.

Features:

• Scheduled shutdown with configurable "Bedtime Zone" and "Safe Zone" times

• User notifications via desktop and terminal (wall)

• Configurable grace periods for user and system

• Emergency override options (USB stick, USB device ID, or block device label)

• Dry-run mode for safe testing (can run as non-root with readable config)

• Comprehensive logging with optional log file support

• Multiple verbosity levels for debugging

Quick Start:

# Optional: Test in dry-run mode first (no sudo or system changes needed!)
cp bedtime-shutdown/bedtime-shutdown.conf /tmp/bedtime-shutdown.conf
editor /tmp/bedtime-shutdown.conf
./bedtime-shutdown/bedtime-shutdown.sh --config /tmp/bedtime-shutdown.conf --dry-run -v

# Deploy and configure (requires sudo)
cd bedtime-shutdown
sudo ./install.sh
sudo editor /etc/bedtime-shutdown.conf
# Now follow the instructions shown by the install script (systemd service unit/timer etc.)

📖 Full Documentation: See bedtime-shutdown/README.adoc for detailed installation, configuration, and usage instructions.
