How can I send a process a message from a shell script?
Is there a straightforward way to send a message to my Elixir process from a bash script?
To avoid the XY problem, I am trying to implement a pianobar eventcmd, which is a script that is run on each event (such as song change) and receives the majority of it’s input via stdin. Should I use a pipe? I could do an HTTP Request but that seems awfully inefficient.

I can think of solving this a number of ways. Do you have distribution available? If not i would use a domain socket if you are on a Linux or OSx machine. (i think OSX supports unix domain sockets)
From an iex session:
{:ok, sock} = :gen_udp.open(0, [{:ifaddr, {:local, '/tmp/testsockin'}}])
and from a shell
echo 'Hello, World!' | socat - UNIX-SENDTO:/tmp/testsockin
