# 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 rtorrent.rc.
# If you typically just start rtorrent with just "rtorrent" on the
# command line, all you need to change is the "user" option.
# Attach to the screen session as your user with
# "screen -dr rtorrent". Change "rtorrent" 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 whateve reason you want to)
# by commenting out/deleting the configuration lines and placing them
# in a text file (say /home/user/.rtorrent.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/rtorrent.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
user="kane"
# the system group to run as, not implemented, see d_start for beginning implementation
# group=`id -ng "$user"`
# the full path to the filename where you store your rtorrent configuration
config="`su -c 'echo $HOME' $user`/.rtorrent.rc"
# set of options to run with
options=""
# default directory for screen, needs to be an absolute path
base="`su -c 'echo $HOME' $user`"
# name of screen session
srnname="rtorrent"
# file to log to (makes for easier debugging if something goes wrong)
