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

##Start Configuration##
#######################
# You can specify your configuration in a different file
# (so that it is saved with upgrades, saved in your home directory,
# or whatever reason you want to)
# by commenting out/deleting the configuration lines and placing them
# in a text file (say /home/user/.sickbeard.init.conf) exactly as you would
# have written them here (you can leave the comments if you desire
# and then uncommenting the following line correcting the path/filename
# for the one you used. note the space after the ".".
# . /etc/sickbeard.init.conf


#Do not put a space on either side of the equal signs e.g.
# user = user
# will not work
# system user to run as (can only use one)
user="CHANGEME"

# system user to run as # not implemented, see d_start for beginning implementation
# group=$(id -ng "$user")

# set of options to run with each instance, separated by a new line
# must keep parentheses around the entire statement
#if no special options, specify with: ""
options=("")
# Examples:
# starts one instance, sourcing both .sickbeard.rc and .sickbeard2.rc
# options=("-o import=~/.sickbeard2.rc")
# starts two instances, ignoring .sickbeard.rc for both, and using
# .sickbeard2.rc for the first, and .sickbeard3.rc for the second
# we do not check for valid options
# options=("-n -o import=~/.sickbeard2.rc" "-n -o import=~/sickbeard3.rc")

# default directory for screen, needs to be an absolute path
base=$(su -c 'echo $HOME' $user)

# name of screen session
srnname="sickbeard"

# file to log to (makes for easier debugging if something goes wrong)
