# This script depends on tmux and is based on 'rtorrentInitScreen.sh' script
|
||||
# with the following enhancements:
|
||||
# - init script 'start' option can be called without breaking anything
|
||||
# - init script 'status' option can be used in scripts to determine whether rtorrent is running or not
|
||||
# - auto removes damaged/stuck 'rtorrent.lock' file if necessary
|
||||
# - saves session (just in case) before stopping with 'rtxmlrp' if it exists
|
||||
# - provides examples how to script tmux windows
|
||||
#
|
||||
# For the stop function to work, you must set an explicit session directory
|
||||
# using ABSOLUTE paths (no, ~ is not absolute) in your rtorrent.rc and with
|
||||
# "sessiondir" option.
|
||||
# If you typically just start rtorrent with just "rtorrent" on the
|
||||
# command line, all you need to change is the "user" and "sessiondir" option.
|
||||
# Attach to the tmux session as your user with
|
||||
# "tmux -2u new-session -A -s rtorrent". Change "rtorrent" with "tmuxname" option.
