## Overview

The Shutdown Timer is a utility tool that generates custom scripts to automate power management tasks, including shutdown, restart, sleep, and hibernation, for Windows, macOS, and Linux systems.

## Inputs

- **Delay Unit** (select)
- **Show Warning Message** (checkbox)
- **Custom Warning Message** (text): Enter custom message (optional)

## When to use

- When you need to leave your computer running for a specific task and want it to power off automatically afterward.
- When you want to schedule a system restart or sleep mode to save energy during idle hours.
- When you need to ensure a system logs off or shuts down at a precise time without manual intervention.

## How it works

- Select your operating system and the desired power action from the available options.
- Set the delay time and choose the appropriate unit (seconds, minutes, or hours).
- Optionally customize the warning message to display before the action executes.
- Generate the script and run it on your machine to initiate the scheduled task.

## Use cases

- Automating overnight system shutdowns after long file downloads or rendering tasks.
- Scheduling a system restart during off-hours to clear memory and improve performance.
- Setting a sleep timer for your computer while listening to music or podcasts before bed.

## Frequently asked questions

### Can I cancel a scheduled shutdown once it has started?

Yes, you can typically cancel a pending shutdown command via your system's command line interface (e.g., 'shutdown -a' on Windows).

### Does this tool work on all operating systems?

The tool supports Windows, macOS, and Linux by generating the appropriate command-line script for each environment.

### What happens if I have unsaved work open?

Unless you enable the force close option, the system may prompt you to save your work before shutting down, depending on your OS settings.

### Is the warning message mandatory?

No, you can toggle the warning message off if you prefer the system to execute the action silently.

### What is the maximum delay time I can set?

You can set a delay of up to 10,080 minutes (one week).
