init.d Script

Notes

This should be installed at /etc/init.d/ as transmission-daemon. Make the script executable:

chmod +x /etc/init.d/transmission-daemon

Use

Start and stop it manually by calling the init-script yourself.

/etc/init.d/transmission-daemon start

To stop transmission, just call the init-script with the "stop" parameter:

/etc/init.d/transmission-daemon stop

Do it the fancy way and let transmission start at boot-time. To do so you can use a tool like update-rc.d to update your runlevels:

update-rc.d defaults transmission-daemon
