[erlang-questions] I need a little newcomer help with basic STDIN\OUT code.

[Daniel Goertzen]

The program below will read and then write one line at a time; hopefully it
will help you get started.  Keep in mind that the task you describe isn't
going to touch on concurrency or any of the other great parts of Erlang.
 Try writing a little proxy server, then you will have fun. :)


#!/usr/bin/env escript

main(_Params) ->
handle().

handle() ->
handle(io:get_line([])).

handle(eof) ->
halt(0);

handle(Data) ->
io:format("~s", [Data]),
handle().
