exiting the repl console with a background process
提问by Lee Mighdoll
How do you exit from the repl console in sbt with a background process running? The following hangs:
如何在后台进程运行的情况下退出 sbt 中的 repl 控制台？以下挂起：
$ sbt
> console
Welcome to Scala version 2.9.1.final (Java HotSpot(TM) 64-Bit Server VM, Java 1.6.0_26).
scala> import scala.sys.process._
import scala.sys.process._
scala> "sleep 10000".run
res0: scala.sys.process.Process = scala.sys.process.ProcessImpl$SimpleProcess@67219b8c
scala> <ctrl-d entered>
...hangs
ctrl-c works, but kills sbt too. I suppose I'm looking for a letter between ctrl-c and ctrl-d.
ctrl-c 有效，但也会杀死 sbt。我想我正在寻找 ctrl-c 和 ctrl-d 之间的字母。

Enter :qto quit the console (it will lead to some sort of hanging), and, then, ctrl+c.
Enter:q退出控制台（它会导致某种挂起），然后，ctrl+c.
