You may also use io:format/3 to selectively output to different
destinations.
RP = rpc:call(Node1,erlang,list_to_pid,["<0.0.0>"]),
io:format(RP,"Hello World !\n",[]).
A side note on use of io:format for remote logging:
Using io:format directly for logging is not an ideal solution.
io:format may cause the calling process to hang if the output file
handling process disappears.
It is better to have your own protocol for distributing log events to
a logger server on the remote node that does the actual io.
