11:36 <cymen> TauPan: got any good examples? :)
12:12 <TauPan> cymen: Not sure if it's good, but here is an example: https://gist.github.com/TauPan/3cb72c76312ee2f0f45ecc071340f4b0 (I'm open for suggestions, of course.)
12:13 <TauPan> I use this to update my boxes at home, all of which run a debian derivate and one has to be woken up with wakeonlan.
12:16 <TauPan> (tmux-select-window-globally is potentially vulnerable if a malicious entity manages to control your session/window/pane names or titles)
12:17 <TauPan> (e.g. if I had the topic of an irc channel in the pane title and somebody would place a shell injection in there, I'd be toast ;)

TMUX_MAIN_SESSION is set in my shell profile
