这将产生以下结果：
Initializing Ruby Program This is main Ruby Program
Ruby END 语句
语法:
END {
code
}
声明代码被称为程序的结束。
语法:
#!/usr/bin/ruby
puts "This is main Ruby Program"
END {
puts "Terminating Ruby Program"
}
BEGIN {
puts "Initializing Ruby Program"
}
这将产生以下结果：
Initializing Ruby Program This is main Ruby Program Terminating Ruby Program
Ruby 注释:
注释隐藏一行，某一行的一部分或几行Ruby解释器忽略解释程序代码。可以使用的的哈希字符（＃）开头的一行：
# I am a comment. Just ignore me.
或者，注释可能是在同一行后一个语句或表达式：
name = "Madisetti" # This is again comment
可以注释掉多行如下：
# This is a comment. # This is a comment, too. # This is a comment, too. # I said that already.
这里是另一种形式。此块注释隐藏几行注释： =begin/=end:
=begin This is a comment. This is a comment, too. This is a comment, too. I said that already. =end
