为什么是它可以Cygwin的脚本蝙蝠运行？ [英] Why is it that Cygwin can run .bat scripts?

问题描述

当我执行从庆典在Cygwin中一个蝙蝠脚本，由它是运行的机制？我明白，如果我运行一个.EXE，将推出，无论.EXE是从Cygwin的或更传统的环境。我明白，当我执行可执行脚本以＃！在那个Cygwin的提供为它运行的魔力开始。

When I execute a .bat script from bash in Cygwin, by what mechanism is it running? I understand that if I run a .EXE it will launch, regardless of whether the .EXE is from Cygwin or from a more traditional environment. I understand that when I execute an executable script with #! at the beginning that Cygwin supplies the magic for it to run.

但是，为什么一个蝙蝠脚本的工作？是否有Cygwin的内部某个组件是知道什么一个Windows的.bat脚本，并与它做什么？或者是它，它是Windows下莫名其妙地无法执行呼叫发起.EXE文件，将不会自动也为蝙蝠脚本的工作呢？

But why does a .bat script work? Is there some component inside of Cygwin that is aware of what a Windows .bat script is and what to do with it? Or is it that it is somehow impossible under Windows to execute a call to launch a .EXE file that won't automatically also work for a .bat script instead?

推荐答案

我相信这cygwin的bash中看到蝙蝠扩展名被标记可执行文件（一个cygwin命中尖Windows约定）。因此，它加载并执行与它相关联的文件间preTER（CMD.EXE，每个操作系统配置），更因为它创造的bash的一个新实例来运行你的＃！ （每POSIX标准）的脚本。

I believe that bash in cygwin sees the bat extension as being flagged executable (a cygwin hit-tip to windows convention). As such it loads and executes the file with it's associated interpreter (cmd.exe, per os configuration), much as it creates a new instance of bash to run your #! scripts (per posix standard).
