Simple Batch Question...

[Twinkie]

I have a little program I made to time a shutdown because Vista has a 10 minute limit to the shutdown time (in XP the limit it more than 6977 or so years XD).

@echo off
title Shutdown Timer
color 0c
set /p sec = "Enter amount of seconds: "

:LOOP
echo %sec%
ping localhost -n 2 > nul
set /a sec=%sec%-1
cls

if (%sec%-30==0) (
shutdown /s /t 30
) ELSE (
goto LOOP
)

It pauses, writes "echo is off" and then counts down from 0. Whats wrong with this??

set /a sec = %sec%-1

I think this should be:
set /a sec = %sec% + 1

Although not required, I also think it would be good to give %sec% an initial value of 0.

Thank you for the suggestion, but this is supposed to be a countdown timer from a certain number of seconds until the computer shuts down. Changing the plus to a minus changes the effect, but it is still incrementing from 0 instead of the number specified. Thank very much for your help!

BTW: Nice avatar, I have a dog just like it ^^

2 things: remove the spaces around the equals sign in the first set command and use timeout rather than the busywait.

I don't know what the second thing you said meant, but removing the spaces works, thanks XD

Rather than looping (basically a busywait), use "timeout /T %secs%". Did you read the link I posted?

timeout doesn't work on xp or vista

timeout works just fine for me in Vista. It doesn't exist under XP, but the poster doesn't need it for XP. If he did, he could get sleep from the Win23K resource kit tools and use that.
