ps aux | grep ruby
you'll get something like:
你会得到类似的东西：
username 917 52.7 0.4 2455912 17484 s000 R+ 9:22AM 0:01.13 /Users/yourusername/.rvm/rubies/ruby-1.9.2-p180/bin/ruby script/rails c
you'll need the "917" id:
你需要“917”ID：
sudo kill -9 917
(also i think this should be migrated to superuser.com)

You can come out from console screen by simply typing 'exit' on console and pressing 'enter'.
您只需在控制台上键入“exit”并按“enter”即可从控制台屏幕出来。
but today i faced some weird issue, when i displayed all records available in table which exceeds console screen size
但是今天我遇到了一些奇怪的问题，当我显示表格中超过控制台屏幕大小的所有可用记录时
then i pressed enterbutton until we reach end of records, now if we press "Control + C", "Control + Z" and exit commands nothing worked for me.
然后我按下回车按钮，直到我们到达记录的末尾，现在如果我们按下“Control + C”、“Control + Z”和退出命令，对我来说没有任何作用。
I get stuck on console screen and screen was not allowing me to do anything.
我卡在控制台屏幕上，屏幕不允许我做任何事情。
