  5. # This script depends on screen.
  6. # For the stop function to work, you must set an
  7. # explicit session directory using absolute paths (no, ~ is not absolute) in your sickbeard.rc.
  8. # If you typically just start sickbeard with just "sickbeard" on the
  9. # command line, all you need to change is the "user" option.
  10. # Attach to the screen session as your user with
  11. # "screen -dr sickbeard". Change "sickbeard" with srnname option.
