I don't think my tmux does support multiline quotes :( however i have it
working with this:
set -g remain-on-exit on
set-hook -g pane-died {
if -F "#{&&:#{==:#{window_name},netkit-vm},#{==:#{pane_index},0}}" {
run-shell "tmux -L netkit has-session -t '=#{session_name}-dead' &&
tmux kill-session -t '=#{session_name}-dead'; tmux -L netkit rename-session
-t '=#{session_name}' '#{session_name}-dead'"
} {
run-shell "tmux -L netkit kill-pane -t
#{session_name}:#{window_name}.#{pane_index}"
}
}
Thanks for your help!!
