# 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.

# 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

# system user to run as
user="$USER"
