So this worked:
~/OSS/elixir[jv-basic-releases %]$ mkfifo test.pipe
~/OSS/elixir[jv-basic-releases %]$ erl
Erlang/OTP 21 [erts-10.0] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [hipe]
Eshell V10.0 (abort with ^G)
1> Fifo = open_port("test.pipe", [eof]),
1> receive
1> Msg -> io:format("Got ~p", [Msg])
1> end.
Got {#Port<0.5>,{data,"foo\n"}}ok
After typing the receive, I ran echo "foo" > test.pipe in another terminal. Could it be something related to permissions as the error message says?
