命令提示符：从任何文本文件执行命令（没有“.bat”或“.cmd”扩展名）

Question

I can't find any way to do, for example, the following:

cmd.exe /C "script.txt"

In other words, I need Command Prompt to (try) to execute file with any extension (not necessarily .bat or .cmd ) if it contains valid batch script code. I'm looking for behavior similar to Unix shells:

./script.txt

While on Unix the shebang ( #!/bin/sh ) is responsible for understanding that the file is actually a script, it seems like on Windows .bat or .cmd extensions play the same role, indicating a batch script file for Command Prompt.

Is it possible to avoid that and force Command Prompt to interpret a file with any name?

NOTE: Please, no answers like:

Give your file .bat or .cmd extension.

That's not what the question is about.

Answer 1

This depends on the complexity of the NON-Batch file. If the NON-Batch file does not use these facilities:

• Access to Batch file parameters via %1 %2 ... and execution of SHIFT command.
• Execution of GOTO command.
• Execution of CALL :NAME command (internal subroutine).
• Execution of SETLOCAL/ENDLOCAL commands.

then you may execute any file as a "Batch file" via this trick:

cmd < anyFile.ext

Answer 2

you first need an "installation" script :

   @echo off

    rem :: A files with .TEST extension will be able to execute batch code but is not perfect as the %0 argument is lost

    rem :: "installing" a caller.
    if not exist "c:\caller.bat" (
       echo @echo off
       echo copy "%%~nx1"  "%%temp%%\%%~nx1.bat" /Y ^>nul
       echo "%%temp%%\%%~nx1.bat"  %%*
    ) > c:\caller.bat

    rem :: associating file extension
    assoc .test=batps
    ftype batps=c:\caller "%%1" %*

then try a simple .test file:

@echo off
for /l (1;1;10) do (
  echo testing .TEST extension
)

In fact ASSOC and FTYPE both have immediate effect so you can start a .test file right after "installation". With direct editing of the registry eventually you can get more control -> How to create file extension that behaves as .cmd/.bat? .
