How do I Quit IRB from the command line? (Using terminal on mac)
提问by Starkers
Basically, I'm typing along just fine in terminal, using IRB to run ruby commands:
基本上，我在终端中输入得很好，使用 IRB 运行 ruby 命令：
2.0.0-p0 :014 > bank_account.withdraw(2222)
=> -1222
But sometimes I accidentally miss out a quotation mark.
但有时我不小心漏掉了一个引号。
2.0.0-p0 :020 > BankAccount.create_for("Jim","Johnson)
2.0.0-p0 :021"> bank_account.withdraw(333)
If you look carefully, you'll see that the speech mark I missed out appears next to the line number on the left, next to the patch version.
如果仔细观察，您会看到我遗漏的语音标记出现在左侧行号旁边，补丁版本旁边。
From here on in, that speech mark appears everytime I run a command! And it stops the commands working:
从这里开始，每次我运行命令时都会出现那个语音标记！它停止命令工作：
2.0.0-p0 :021"> BankAccount.create_for("Julian","Hurley")
2.0.0-p0 :022"> BankAccount.create_for("Katt","Smith")
2.0.0-p0 :023"> exec(##代码##)
What I want to know is, how do I get rid of that quotation mark? Or quit IRB from the command line in order to reset it?
我想知道的是，如何去掉那个引号？或者从命令行退出 IRB 以重置它？

If you haven't closed a quote, just put a quote in and hit return.
如果您还没有关闭报价单，只需输入报价单并按回车键即可。
Exiting from the console can be done by typing exit, though in the circumstance your are would need to hit Control - C
可以通过键入 exit 从控制台退出，但在这种情况下，您需要按 Control - C

Control - C followed by Control - Z. I hope it helps!
Control - C 然后是 Control - Z。我希望它有帮助！

Use Ctrl-D, it is an end-of-input for irb. If you are in the middle of some command, use Ctrl-C first to terminate the input of this command.
使用Ctrl-D，它是 irb 的输入结束。如果您正在执行某个命令，请先使用 Ctrl-C 来终止该命令的输入。
