I feel like I'm missing something stupid obvious, but I've looked all over and can't find the answer to my question.
Suppose I have an application release that I've built with rebar and I start it a la
rel/my_app/bin/my_app start
I let it happily go about its business for a while, and then I want to attach a console to check on things, so I do
rel/my_app/bin/my_app attach
and get a shell. I muck around, and then when I'm done I want to quit the shell but leave the application running. If I do ^G q or q()., it brings down the entire application.
I've also played with starting the app with +Bi to stop it from allowing someone to accidentally close it, but then how does one even exit an attached shell at all?
I don't use rebar, I've never understood what problem it was meant to solve, but I assume when you "attach" you are doing the same thing as running to_erl. To exit in from this you type control-D (EOF).
