SYNOPSIS[autossh or ssh options] <[user@]host> [autossh or ssh options] <[user@]host> [autossh or ssh options] <[user@]host>
DESCRIPTIONrscreen/ruscreen/rtmux is a script to use autossh to open up a remote screen, screen -U or tmux session, or reconnect to an existing one.
Based on autossh's original rscreen example script as installed on Debian systems into /usr/share/doc/autossh/examples/rscreen, but with more generally usable defaults.
ruscreen and rtmux are just symbolic links to the rscreen script and the script checks under which name it has been called.
