How to Use the CHOICE Command for User Input in Batch Script

Creating interactive scripts that present users with a menu of options is a great way to build powerful and user-friendly tools. While SET /P can capture any string a user types, it's often better to restrict their input to a specific set of valid keys (like Y/N). For this, the CHOICE command is the perfect tool.

This guide will teach you how to use the built-in CHOICE command to create simple and effective user menus. You will learn how to define the allowed keys, how to read the user's selection using %ERRORLEVEL%, and how to add features like a timeout and a default option.

The Core Command: CHOICE​

The CHOICE command is designed for one specific task: to pause the script, prompt the user to press one of a predefined set of keys, and report which key was pressed. It is far more controlled than the free-form SET /P command.

The basic syntax is: CHOICE /C <Choices> /M "<Message>"

  • /C: Defines the set of valid Choices.
  • /M: Defines the prompt Message to show the user.

Basic Example: A Simple Yes/No Prompt​

This script asks the user a simple question and waits for them to press either the Y or N key.

@ECHO OFF
ECHO --- Simple Yes/No Prompt ---
CHOICE /C YN /M "Do you want to continue?"

REM Logic to handle the choice will go here.
ECHO.
ECHO The script continues...

The script will display the message and a prompt showing the valid keys, then wait for a keypress.

--- Simple Yes/No Prompt ---
Do you want to continue? [Y,N]?

Once the user presses Y or N (but not any other key), the command ends, and the script proceeds.

How to Read the User's Selection (%ERRORLEVEL%)​

This is the most critical concept for using CHOICE. The command does not set a variable; instead, it communicates the user's selection by setting the %ERRORLEVEL% system variable.

The %ERRORLEVEL% is set to the 1-based index of the key that was pressed in the choice list. For CHOICE /C YN:

  • If the user presses Y, %ERRORLEVEL% will be 1.
  • If the user presses N, %ERRORLEVEL% will be 2.
  • If the user presses Ctrl+C to abort, %ERRORLEVEL% will be 0.

An example of script:

@ECHO OFF
CHOICE /C YN /M "Do you agree?"

ECHO.
IF %ERRORLEVEL% EQU 2 (
    ECHO You chose 'N'. Exiting.
    GOTO :EOF
)
IF %ERRORLEVEL% EQU 1 (
    ECHO You chose 'Y'. Proceeding...
    REM (More commands would go here)
)

Key CHOICE Parameters Explained​

  • /C <Choices>: (Required) The list of valid keys. Example: /C 123 or /C YNC.
  • /M "<Message>": The prompt Message to display.
  • /N: No prompt. Hides the default [Y,N]? text, giving you full control over the prompt's appearance.
  • /T <Timeout>: Sets a Timeout in seconds. If the user doesn't press a key in time, a default choice is made.
  • /D <DefaultChoice>: Specifies the Default choice to be used with /T. This must be a character from your /C list.

Common Pitfalls and How to Solve Them​

Problem: The ERRORLEVEL Check Order is Important​

If you use the classic IF ERRORLEVEL N syntax, you must check the values in descending order. This is because IF ERRORLEVEL N means "if the error level is N or greater".

Example of script with error:

REM This is WRONG. The first check will always be true.
IF ERRORLEVEL 1 ECHO You chose Yes.
IF ERRORLEVEL 2 ECHO You chose No.

Solution: Use EQU or Check in Descending Order​

  1. Use EQU (Recommended): The modern IF %ERRORLEVEL% EQU N syntax is exact and unambiguous. The order doesn't matter. This is the best practice. 
    IF %ERRORLEVEL% EQU 2 GOTO :ChoiceNo
    IF %ERRORLEVEL% EQU 1 GOTO :ChoiceYes
  2. Descending Order: If you must use the classic syntax, check from highest to lowest. 
    IF ERRORLEVEL 2 GOTO :ChoiceNo
    IF ERRORLEVEL 1 GOTO :ChoiceYes

Problem: The Prompt is Case-Sensitive​

By default, /C YN only accepts uppercase Y and N.

Solution: Include Both Cases​

The easiest way to handle this is to include both cases in your choice list and structure your logic accordingly.

CHOICE /C yYnN /M "Proceed? (y/n)"
REM y=1, Y=2, n=3, N=4
IF %ERRORLEVEL% GEQ 3 GOTO :No
IF %ERRORLEVEL% GEQ 1 GOTO :Yes

Here, we use GEQ (Greater than or Equal to) to group the lowercase and uppercase results.

Problem: Adding a Timeout and Default Choice​

For unattended scripts, you can combine /T and /D to proceed automatically if there is no user interaction.

CHOICE /C YN /T 10 /D Y /M "Start backup now? Defaulting to YES in 10 seconds."

This will wait 10 seconds, and if no key is pressed, it will automatically select Y and continue.

Practical Example: A Multi-Option Menu​

This script presents the user with a menu of actions to perform. CHOICE is perfect for this, as it prevents the user from typing an invalid option.

@ECHO OFF
SETLOCAL

:Menu
CLS
ECHO --- System Maintenance Menu ---
ECHO.
ECHO   1. Check Disk Space
ECHO   2. Ping Gateway
ECHO   3. View IP Configuration
ECHO   Q. Quit
ECHO.

CHOICE /C 123Q /N /M "Please enter your choice: "

REM Use modern, exact checks for ERRORLEVEL
IF %ERRORLEVEL% EQU 4 GOTO :Quit
IF %ERRORLEVEL% EQU 3 GOTO :ViewIP
IF %ERRORLEVEL% EQU 2 GOTO :PingGateway
IF %ERRORLEVEL% EQU 1 GOTO :CheckDisk

:CheckDisk
ECHO --- Checking Disk Space ---
FSUTIL volume diskfree C:
PAUSE
GOTO :Menu

:PingGateway
ECHO --- Pinging Gateway ---
PING -n 4 192.168.1.1
PAUSE
GOTO :Menu

:ViewIP
ECHO --- Viewing IP Configuration ---
IPCONFIG /ALL
PAUSE
GOTO :Menu

:Quit
ECHO Exiting.
ENDLOCAL

Conclusion​

The CHOICE command is the ideal tool for creating simple, controlled user prompts in batch scripts. It is far more robust than SET /P for menu-driven applications because it restricts the user's input to only the valid options you define.

Key takeaways:

  • Use /C to define the set of allowed keys.
  • Read the user's selection from the %ERRORLEVEL% variable, which corresponds to the 1-based index of the choice.
  • Use the modern IF %ERRORLEVEL% EQU N syntax for clear and unambiguous checks.
  • Use /T and /D to create timed prompts that can default to a specific action in unattended scripts.
