How to show all processes in Erlang?

Question

I need get all registered process. I input register(). a

 mnesia_event,kernel_safe_sup,mnesia_monitor,mnesia_snmp_sup,
 mnesia_recover,mnesia_late_l         


        

Answer 1

> rp(registered()). Documentation here

Answer 2

I believe the easiest way is:

> io:write(registered()).

Answer 3

registered() is returning all the processes, but the shell is truncating output.

you can print the result to see everything:

io:format("~p~n", [registered()]).

Answer 4

As long as your are in shell you can use regs():
