Displaying messages in a remote node IO

[Vladimir Sekissov]

Good day,

As in Unix all IO is sent to group leader process.

There is a trick I've got from:

http://www.erlang.org/ml-archive/erlang-questions/200205/msg00004.html

If we on Node2:

RP = rpc:call(Node1,erlang,list_to_pid,["<0.0.0>"]),
erlang:group_leader(RP,self()),               
io:format("Hello World !\n").

and all output from your process will be redirected to Node1.

Best Regards,
Vladimir Sekissov
