halt Command Generator

## What is halt?

The `halt` command stops the system by terminating all running processes and halting the CPU(s). By default it logs the action through `shutdown` so other users are notified. Use it to bring a machine to a clean stop without necessarily removing power.

## How to Use

1. **Pick Options**: Choose force, power-off, or write-only behaviour. 2. **Run as Root**: Execute the generated command with `sudo` or as root. 3. **Confirm**: The system notifies logged-in users and proceeds to halt. 4. **Copy & Run**: Copy the generated command into your terminal.

> `halt`, `poweroff`, and `reboot` share the same flag set. Use `-p` to also switch off the machine, or prefer `poweroff` directly when removing power is the goal.

### `-f` Force Force an immediate halt without calling `shutdown`. No notification is sent to users and no clean shutdown sequence runs — use only when the system is unresponsive.

### `-p` Power off Switch off the machine after halting. Equivalent to running `poweroff`.

### `-w` Write only Write a `wtmp` shutdown record but do not actually halt. Useful for testing logbook entries on a non-live system.

### `-d` No wtmp Do not write a `wtmp` record. Useful in containers or recovery environments where the accounting log is unavailable.
