Hi,

is there a way to access session environment variables from an already running window?

In my example I:
1- create a session then detach from it
2- start a new shell set an environment variable (the variable is included in the update-environment string)
3- attach to old session from this shell 
4- variable is visible in the session environment if I type “tmux show-environment” but I can’t access it from
    currently running windows, must create a new window to access it.

Many thanks,

tmux can't affect variables in panes that already contain a running process. The only way is to set them yourself (perhaps by getting the values from tmux getenv).
