Batch - Countup Timer - batch-file

Question

I'm trying to make a countup timer in batch and so far, I have this
:timer
set time=0
:time
set /a time=%time%+1
ping localhost -n 2 >nul
goto time
The problem is, I want this to run at the same time another event is happening in the same batch file. How can I do this?

Answer 1

Are you wanting to time how long it takes to execute your batch script? If you have PowerShell installed you can use the Measure-Command cmdlet.
Save this as timeit.bat:
#echo off
>~timeit-%~n1.bat echo(%*
powershell "Measure-Command {Start-Process ~timeit-%~n1.bat -Wait}"
del ~timeit-%~n1.bat
Then when you want to time the execution of something, say, systeminfo, just timeit systeminfo.
If you prefer a non-powershell solution (as powershell takes several annoying seconds to prime itself in its first run per Windows session), here's a faster batch / JScript hybrid solution (more info). It also executes the command in the same window, whereas the powershell solution spawns a new window for your command. Save this as timer.bat:
#if (#a==#b) #end /* begin multiline JScript comment
:: timer.bat command args
:: measures execution time of a command
#echo off & setlocal
if "%~1"=="" (
echo Usage: %~nx0 command args
goto :EOF
)
cscript /nologo /e:JScript "%~f0" %*
goto :EOF
:: end batch portion / begin JScript */
var osh = new ActiveXObject('wscript.shell'), cmd = [], b4 = new Date();
for (var i=0; i<WSH.Arguments.length; i++) {
var arg = WSH.Arguments(i);
cmd.push(/\s/.test(arg) ? '"' + arg + '"' : arg);
}
var exe = osh.Exec('cmd /c ' + cmd.join(' '));
while(!exe.StdOut.AtEndOfStream) WSH.Echo(exe.StdOut.ReadLine())
var x = (new Date() - b4) / 1000,
d = Math.floor(x / 86400),
d = d ? d + ' days ' : '',
h = ('0' + (Math.floor(x / 3600) % 24)).slice(-2),
m = ('0' + (Math.floor(x / 60) % 60)).slice(-2),
s = Math.floor(x % 60) + x % 1,
s = (s < 10) ? '0'+s : s;
WSH.Echo('\r\nExecution completed in ' + d + h + ':' + m + ':' + s);
