[erlang-questions] [Erlang-Q] What does Ctrl+G do for the Eshell?

[Barco You]

Hello Erlangers,

When starting a erl shell, we will see a printout as:
Eshell V5.8.4  (abort with ^G)


then, I tried to press Ctrl+G and got:
User switch command
 --> ls
Unknown command
 --> q().
Unknown command
 -->

I can do nothing with the prompt "-->". How to quit from it? and
what's "Ctrl+G" used for?


Thank you!
Barco
