在ruby中执行外部程序并等待其执行 [英] Execute external program in ruby and wait for its execution

问题描述

如何从ruby启动一个外部程序（如excel表），等待其执行。

How do I start an external program (like an excel sheet) from ruby and wait for its execution resp. termination before continuing.

我知道我可以开始使用

system 'start excel "my/path/to/the/sheet"' 

只会启动工作表，然后继续。

but using this will only start the sheet and then continues.

推荐答案

您遇到的问题不在于Ruby，而是启动命令，另一个程序并立即返回。您需要使该命令等待excel完成使用等待标志：

The problem you are having is not with Ruby but the start command, this launches another program and returns immediately. You need to make that command wait for excel to finish using the wait flag:

system('start /wait excel "my/path/to/the/sheet"')
