I have a long running ruby script, in Linux, which has some interesting data stored in a hash table. The program does not have any persistence mechanism and I am interested in copying the data from it's hash table. Is there any way to copy data from the memory of a running ruby script?
我有一个长期运行的ruby脚本，在Linux中，它有一些有趣的数据存储在散列表中。程序没有任何持久性机制，我对从它的散列表中复制数据感兴趣。是否有办法从运行的ruby脚本的内存中复制数据?

It's not for the faint of heart, but there's a tool called Hijack that can give you a live irb prompt to a running ruby process. RubyInside has a very brief rundown and example of how to use it.

It would be very easy to add a signal handler that responds by dumping a serialized version of your hashtable.
很容易添加一个信号处理程序，该处理程序通过转储您的hashtable的序列化版本来响应。
See Signal.trap.
