Windows Batch-File to execute and communicate with running program

Question

(How) can a program with interactive command line mode (shell) be programmatically "interacted" with from CMD.exe via batch file (.bat)? Example:

>program.exe
>>aCommand
>>someResponse
>>anotherCommand
>>someotherResponse
>>quit
>

The batch file should start program.exe, send aCommand, then [optionally] wait for someResponse and so on.

There's How to interact with command-line program using batch file? but does not need automated interaction and so accepts CALL as answer.

Maybe it's possible to start the process separately and then pipe commands and responses to communicate with it?

Answer 1

Various mechanisms exist for .bat files, although very limited.

Microsoft DOS set command

Syntax : SET /P variable=[promptString]

Example :

ECHO 1. Print Hello
ECHO 2. Print Bye
ECHO 3. Print Test
set choice=
set /p choice=Type the number to print text.

Microsoft DOS choice command

Syntax : CHOICE [/C choices] [/N] [/CS] [/T timeout /D choice] [/M text]

Example :

CHOICE /C YNC /M "Press Y for Yes, N for No or C for Cancel."

Pause command

Syntax : pause

Issues the message "Press any key to continue . . ." and waits for any key.
