Why is it that Cygwin can run .bat scripts?
提问by skiphoppy
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.
当我在 Cygwin 中从 bash 执行 .bat 脚本时，它是通过什么机制运行的？我知道，如果我运行 .EXE，它将启动，无论 .EXE 是来自 Cygwin 还是来自更传统的环境。我知道当我用 #! 一开始，Cygwin 为其提供了运行的魔力。
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?
但是为什么 .bat 脚本可以工作？Cygwin 内部是否有一些组件知道 Windows .bat 脚本是什么以及如何处理它？或者在 Windows 下执行调用以启动 .EXE 文件是不可能的，该文件不会自动也适用于 .bat 脚本？

跑步
./test.bat params
from bash seems to be equivalent to
from bash 似乎相当于
cmd /c test.bat params

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).
我相信 cygwin 中的 bash 将 bat 扩展视为被标记为可执行文件（cygwin 对 Windows 约定的提示）。因此，它使用关联的解释器（cmd.exe，每个操作系统配置）加载并执行文件，就像它创建一个新的 bash 实例来运行你的 #! 脚本（根据 posix 标准）。

And if you want to fork an *.cmd file execution like a ShellScript process and append his log to an file:
如果你想像 ShellScript 进程一样 fork 一个 *.cmd 文件执行并将他的日志附加到一个文件中：
cmd /c test.bat > nohup.out &
Enjoy!
享受！
