Create new tmux session from inside a tmux session

Question

I\'m writing a shell script that creates / attaches or switches to a given session, depending on whether one is inside tmux and the session exists.

I\'ve got everything

Answer 1

All the commands you can launch within your terminal, like tmux new -s sessionName can be launched from within tmux by pressing the trigger key (eg: ctrl-b) then : then the command without the starting tmux part.

As a result, ctrl-b : followed by new -s sessionName will do exactly what you want and give a name to your session. It also switches automatically to the new session.
