如何遍历通过终端传递给Ruby脚本的bash数组变量的元素？

Question

I have a Bash file called test.sh :

#!/bin/bash
arr=(whatever@gmail.com iamcool@gmail.com)
ruby testScript.rb $arr

And here's testScript.rb :

ARGV.each{|a| p a}

When I run ./test.sh in the terminal, I get this output:

"whatever@gmail.com"

I want my Ruby script to loop through all elements in the Bash array variable $arr . How do I fix my code to do this?

在bash脚本中，像这样传递数组：

ruby testScript.rb "${arr[@]}"
