Custom Commands

Create your own shell commands to execute on your mirror.

⚠️ Security Warning: Custom commands execute shell commands on your system. Only add commands you trust.

Reserved Commands

These commands override the default system commands:

    customCommand: {

        rebootCommand: 'sudo reboot',
        monitorOnCommand: "wlopm --on '*'",
        monitorOffCommand: "wlopm --off '*'",
        monitorStatusCommand: "command -v wlopm > /dev/null 2>&1 || exit 1; wlopm | grep -q ' on$' && echo 'true' || echo 'false'",
    },
},

Custom Commands via API

Since v2.3.0, you can define custom commands that can be triggered via the API:

config: {
    customCommand: {
        myCustomCommand: 'echo "Hello World"',
        takeScreenshot: 'scrot /tmp/screenshot.png',
    },
},

Then call via API:

curl http://your-mirror:8080/api/command/myCustomCommand
