How might I check if I'm in a distrobox container

[givensuman]

I would like to add a few lines to the top of my .bashrc to check if I'm in a distrobox container, and if not, enter one with distrobox enter main. It's probably achievable with just checking an environment variable but I don't see anything related to this anywhere.

Found it: echo $DISTROBOX_ENTER_PATH
