Following one of the comments of one of the responses to this question I've set my default shell to
/usr/bin/tmux, which works perfectly fine.
But now I'd like if I could assign all logins to one account to be attached to the same window-group.
As per this gist that works by adding
new-session -s main
to ~/.tmux.conf and then invoking tmux as
tmux new-session -t main
Is there a way to have this be invoked as the login shell, or have tmux itself attach to the "main" window-group on launch by default?
