DOS batch: looking for user input (Y/N) with a timeout

[marcorocchini]

Hi cats,

for kindness I try to modify a batch so that the script ask to the user:

want u use smooth resize (press Yes "Y")? or LancZosResiZE (press No "N") ?

if (within 3 seconds) the user type "Y" a variable called smoothResize become == 1

otherwise after 3 seconds (even if you do not type anything in the keyboard) the batch have to continue

How can I resolve? thanks

PS: IF POSSIBLE I DON'T WANT USE THE CHOICE COMMAND : THANKS ^^

Would this work from another link?
Use the SET /P command to read input from the user. The SET /P command will print the string you specify and prompt the user for information:

@echo off

SET /P ANSWER=Do you want to continue (Y/N)?
echo You chose: %ANSWER%
if /i {%ANSWER%}=={y} (goto :yes)
if /i {%ANSWER%}=={yes} (goto :yes)
goto :no
:yes
echo You pressed yes!
exit /b 0

:no
echo You pressed no!
exit /b 1

I have do some search on the internet but for example, in your script where is specify the timeout of 3 seconds?

I correct my initial request:

tha batch don't have to differentiate from yes and no: simply the user have to type Y (yes) if he want the smoothresize, in the meantime the countdown goes on. After 3 seconds, if the user have no-input on the keyboard the batch assume to use the normal resize method

only if the user have type Y --> a variable called smoothResize change of state from 0 to 1

Which is the entire reason why "choice" exists, if you don't want to use the only command that was designed for the task, then you're out of luck.

I have a little program that asks whatever is on the command line and returns errorlevel 0 if n/N is pressed, errorlevel 1 if y/Y is pressed. No timeout though.

[Budman1]

This works for me and sets 10 second delay. If you want more change waitMins to minutes and waitMins*10 to waitMins*60. The object is to arrive at Seconds...
1*10=10 seconds... 30*60=1800 Seconds(30 Minutes). You will also have to fill in a valid process to perform instead of the Echo Process1 and Echo Process2. The default is set to n (/d n) so change to /d c if you wish it.

This is documented courtesy of a better DOS person than I at http://stackoverflow.com/questions/12331428/how-to-ask-for-batch-file-user-input-with-a-timeout

----Code Below-----

Echo off
:START
set waitMins=1

echo PC WILL RESTART IN %waitMins% SECONDS: Press N to restart [N]ow or C to [C]ancel
:: Calculate Seconds
set /a waitMins=waitMins*10
:: Choices are n and c, default choice is n, timeout = 1800 seconds
choice /c nc /d n /t %waitMins%

:: [N]ow = 1; [C]ancel = 2
goto Label%errorlevel%

:Label1
echo Process1 here
:: Make sure that the process doesn't fall through to Lable2
goto :eof

:Label2
echo process2 here
::exit

PERHAPS these ones will be helpful

timeout

TIMEOUT - This utility is similar to the DOS PAUSE command.  However, it
          accepts a timeout parameter to specify a length of wait (in seconds)
          at which time it will continue without a key press.

          Written by Eric Brown, Business System Division.
          Copyright (C) Microsoft Corporation, 1992-1995.

Usage -   TIMEOUT <###>
          where <###> is a decimal number of seconds between -1 and 100000.
          The value -1 means to wait indefinitely for a key hit.

sleep --help
Usage: sleep NUMBER[SUFFIX]...
  or:  sleep OPTION
Pause for NUMBER seconds.  SUFFIX may be `s' for seconds (the default),
`m' for minutes, `h' for hours or `d' for days.  Unlike most implementations
that require NUMBER be an integer, here NUMBER may be an arbitrary floating
point number.

      --help     display this help and exit
      --version  output version information and exit

move that question to the beginning of your batch script, it kind of makes little sense to wait long time to confirm something

[Budman1]

The problem I have with 'Sleep' and 'Timeout' as I understand them, is that Sleep does just that and cannot be interrupted with keystrokes and Timeout can be interrupted with key-presses but they have to be set with 'set /p' which again will wait forever until you type something in. No matter which I put first, i couldn't arrive at a maximum timeout that can be shortened by hitting a key and yet fall through automatically if nothing is pressed.

Maybe I missed something but the Choice with timeout accomplished it for me but as I mentioned earlier, I'm far from a DOS Guru.

Considering some of the ridiculous string sequences the average programmer has to memorize, not even having English as a second language can excuse that mistake.
