"tmux attach-session -t 0" is a lot to type when "tmux attach 0" would be just as understandable tbqh
i was informed about ´tmux a´ to attach the lowest numbered terminal (which is all i ever do anyway since i mostly use tmux to protect against disconnects) which is great
@tom tmux a -d is my bff

@tom I personally have this in my .profile:

if [ -z "$TMUX" ]; then tmux attach -d; fi

That way, it tries to reconnect automatically (and disconnect everything else from it, which is important because I connect from differently sized terminals). If there isn't a running tmux, I just have to issue tmux to get one.

@tom my two tmux aliases on every machine are tm for tmux and tma for tmux attach
