Bat文件运行默认程序

Question

有没有办法编写.bat文件，将所有输入发送到后台运行的程序？

像这样，

1. c：\ start.bat
2. 打开新提示

3. 但是我在新提示中键入的内容应该转到后台运行的默认程序（不知道在哪里指定默认程序，我不想每个都显示程序名称我通过论证的时间）。我想使用类似这一行的东西，

   <CUSTOM_PROMPT>"select data from tablex" , the string should go the "programX.bat" 
   

   而不是

   <CUSTOM_PROMPT>programX.bat "select data from tablex"

我担心你的问题不明确;有许多细节需要澄清。但是，下面的批处理文件可以为我们双方提供讨论的起点：

@echo off
setlocal

if "%~1" equ "goto" goto %2

cls
echo I am the user-interface program 
echo Enter "exit" (with no quotes) to end
echo/

"%~F0" goto getInput | "%~F0" goto background > background.txt

echo/
echo The user-interface program ends
echo/
echo This is the input captured by background program:
echo/
type background.txt
goto :EOF


:getInput
set /P "input=<CUSTOM_PROMPT>: " > CON
echo %input%
if /I "%input%" neq "exit" goto getInput
goto :EOF


:background
set /P input=
if /I "%input%" equ "exit" goto :EOF
echo Input received at %time%:
echo %input%
echo/
goto background
