 HOWTO: Automatically run a command when USB-disk is plugged in

Post by goebbe » Tue Oct 08, 2024 3:17 am

The following describes how to run commands automatically when a specific USB-device is plugged in.

This howto has been tested on Linux Mint 22 (based on Ubuntu 24.04). The howto uses systemd. No special privileges are required.

Possible use case: Run a backup script automatically, as soon as you plug in a specific USB-drive.

Howto run a script or a command automatically when a specific .mount unit becomes available:

- Plugin the USB device - by default the device is mounted.
- In the terminal: List all .mount units of the current user to identify the .mount-unit of the USB-device:

  systemctl --user list-units -t mount

- Identify the .mount unit for your USB-device. For example, for a USB-device with label "yourUSBlabel", the following .mount-unit should be available: media-yourusername-yourUSBlabel.mount

- In your text editor: Create/ Place the following Systemd .service-file in ~/.config/systemd/user/auto-usb-command.service
Adapt/ edit the .service file: yourusername, yourUSBlabel, and yourcommand should be replaced accordingly.

  [Unit]
  description=Runs command automatically when the specified usb .mount-unit becomes available
  
  [Service]
  Type=oneshot
  ExecStart=/bin/bash -c '/pathto/yourcommand'
  
  [Install]
  WantedBy=media-yourusername-yourUSBlabel.mount

Important: The user has to be able to run /pathto/yourcommand in the terminal. Scripts / commands have to be executable.

- In the terminal: Start the new service:

  systemctl start --user auto-usb-command.service

- Enable the service:

  systemctl enable --user auto-usb-command.service

Now, whenever you plugin/ mount your USB-device, the specified command will run.

- Finally, after the command has finished, unmount/ safely remove your USB-device.


Maintenance: Useful terminal commands

Check the status of the new service:

  systemctl status --user auto-usb-command.service

After changing the .service file, one has to reload:

  systemctl --user daemon-reload

Detailed Systemd logs:

   journalctl --user -xeu auto-usb-command.service
