[erlang-questions] How to start an erlang applications from the command line non-interactively?

There are a few ways to do what you want. Both of them involve using
the -detached erl arg.

If you are using an application you'll want to create a boot script
using the .app and .rel file. I consider this crucial for deploying
applications.

erl -name myapp@`hostname` -noshell -detached -setcookie myappcookie -boot myapp

If you've got a simple MFA that you want to run in the background you
can do it with -s.

Consider the module foo that exports the method bar:

erl -name fooapp@`hostname` -noshell -detached +W w +A 1 +Ktrue
-setcookie foocookie -s foo bar

Just keep in mind that to connect to detached erlang nodes, you'll
need to be sure your cookies match. Otherwise you should be good to
go.

I tend to do something like:

$ erl -name fooapp_ctl@`hostname` -setcookie foocookie

Eshell V5.6.1  (abort with ^G)
