Execute external program and get the output
I would like to execute command on the host machine. I am using the port Module.
I know the file gets executed because the php script is creating log files. But i dont know how to receive the output back to elixir. I can see the data php script outputed only when i use the flush command.
How can i get the data my external programm outputs?
port = Port.open({:spawn, "php filename.php"}, [:binary])
flush()
{#Port<0.14>, {:data, "some data"}}

As I said, you can use receive to receive the ports messages manually.
Though I’m wondering why neither System.cmd/3 nor porcelain give you the output, perhaps your tool is only printing output after its stdin has been closed? Then this is exactly what rambo was made for, give it a try.

Thank you all for the answers. I can receive messages from the port with the following code:
receive do {_, {:data, msg}} -> IO.puts(msg) end
