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 working great except for the case requiring the creation of a new tmux session from within a tmux session.

When my script executes tmux new-session -s name, I get the following output:

sessions should be nested with care, unset $TMUX to force

I don't actually want to nest sessions, my goal is to create another separate session and switch to it from within a tmux session.

Is this possible?

Answer 1

The quickest way (assuming you use ctrl-b as your command prefix) is:

ctrl-b :new

To create a new session, then

ctrl-b s

to interactively select and attach to the session.
