Bad escape character 'rsion'.
rscreen --help (return code: 0)
Usage: rscreen [autossh or ssh options] <host>
If $RSCREEN_COMMAND is set (either in the environment, in
/etc/rscreenrc, or in ~/.rscreenrc), it will be used instead of screen
or tmux. Use this feature if you want to supply additional screen
options or tmux commands. (Using $RTMUX_COMMAND does not work!)
