System suspend inhibitor

Inhibit.py

Systemd Inhibitor - Prevent system shutdowns and sleep states via stdin ON/OFF commands.

This script creates a systemd inhibitor that can be controlled via stdin. It reads ON/OFF commands from standard input and toggles the inhibition accordingly. This is useful for preventing system shutdowns and sleep states when controlled by external processes through pipes.

Basic Usage:

    # Just an example of valid input values.
    echo "ON" | inhibit
    echo "OFF" | inhibit

    # In practice, an external process emits these values.
    some_process |inhibit

    # Common arguments
    inhibit --what sleep --who "my-app" --why "processing data"

The script uses systemd's logind interface to create inhibitors for:

• sleep: Prevent system sleep/suspend
• idle: Prevent automatic idle detection

For detailed command-line options, use --help.
