如何使用Ruby脚本在其默认应用程序中打开文件?

How to open file in its default application using Ruby scripts?

让我们说，我有一个文件名为.txt .doc .rb的文件夹，我想分别用记事本，Word和RubyMine打开它们.我假设所有文件都有其默认应用程序可以打开.

Let us say, I have folder with files .txt .doc .rb and I would like open them with Notepad, Word, and RubyMine respectively. I assume that all files have their default applications to open.

推荐答案

这应该有效(未经测试，因为我现在不在Windows计算机上):

This should work (untested, as I'm not on a Windows machine now):

file_to_open = "c:\path\to\file.txt"
system %{cmd /c "start #{file_to_open}"}

作为参考，这也可以在OS X上完成:

For reference, this can also be done on OS X:

file_to_open = "/path/to/file.txt"
system %{open "#{file_to_open}"}
