为什么将CMD开头的参数用引号引起来会导致其行为有所不同? [英] Why does wrapping an argument to CMD's start in quotes cause it to behave differently?

问题描述

这只花了我很多时间在批处理脚本中进行调试:

This just took up a good chunk of my time to debug in a batch script:

:: Opens up Chrome
start C:\cygwin64\home\james\code\cs\PolynomialReducer\reports\PolynomialReducer.Tests\index.htm

:: Opens a new command prompt
start "C:\cygwin64\home\james\code\cs\PolynomialReducer\reports\PolynomialReducer.Tests\index.htm"

为什么/如果将参数用引号引起来， start 命令的行为有何不同?

Why/is there any reason the start command behaves differently if you wrap your argument in quotes?

推荐答案

第一个引用的参数假定为窗口标题.如果在 start 和带引号的命令之间插入一组空引号，则应遵守预期的行为.

The first quoted argument is assumed to be a window title. If you insert an empty set of quotes between start and the quoted command, you should observe expected behaviour.
