You need to write a function my:start(). The '-s my' flag is basically
short for '-s my start', that is, "start a process by calling
my:start()". More on that below.

Yes. When you start your Erlang node with SASL activated (e.g. 'erl
-boot start_sasl'), you will get a progress report for every process
started using proc_lib.erl. This includes all processes based on OTP
behaviours (gen_server, gen_fsm, supervisor, ...)

If they really bug you, you can turn them off with the flag 
'-sasl errlog_type error'. This will only give you the error and crash

my:start() needs to start a process (see 'erl -man init'

    "The functions are executed sequentially  in  the  ini-
    tialization  process,  which  then terminates normally
    and passes control to the user. This means that  a  -s
    call  which does not terminate will block further pro-
    cessing; to avoid this, use some variant of  spawn  in
    such cases."

Of course, this man page also recommends that the -run flag be used
instead of the -s flag. In this case, it doesn't matter.

I noticed that Tobbe gave you an example of run.erl, so I'll stop
