Another way to exiting IEX other than ctrl-C

Question

I know we can exit the IEX console with control-C. I\'m curious if there\'s a command to type into the console that would also do the same thing.

1. Disconnect from shell and stop current node. This is what you need in most cases.

   1.1. Ctrl+\ - standard method to quit the Erlang shell. See "4.4 How do I quit the Erlang shell?" in Erlang -- Getting Started.

   1.2. Ctrl+C, a, Enter - via the (a)bort command of the Break menu.

   1.3. Ctrl+C, Ctrl+C - looks like undocumented feature of the Break menu.

   1.4. Ctrl+G, q, Enter - via the q (quit erlang) commant of the User Switch menu (see Erlang -- shell -- JCL Mode).

   Note: this leaves remote node alive if you have connected to it with iex --remsh (see iex --help and IEx -- Remote Shells).

2. Shut down the node you are connected to.

   2.1. System.halt - quick and dirty shut down. The runtime system exits with status code 0 (clean exit without errors). You can also call System.halt(:abort) to abort with core dump. Same as :erlang.halt.

   2.2. :init.stop (System.stop in future versions) - clean shutdown. All applications are taken down smoothly, all code is unloaded, and all ports are closed before the system terminates by calling halt(Status).

   Note: this leaves your shell alive if you have connected to a remote shell with iex --remsh.

Notice that all these options are disabled if Erlang is started with the ignore break, +Bi, system flag: iex --erl +Bi (which can be useful, for example when running a restricted shell). See Erlang -- erl for more info.
