Hi,

I have 17 .bat files.  I want to fire them off at same time.  Is that possible within another script?

any language which supports parallelism can do this job like .net/java etc

Use the call command,

I think in CMD if you use:

call batch.bat ""  <- Leave that double quote there.

You can also execute parallel jobs in Powershell 2 using Background Jobs.
check here:
Can Powershell Run Commands in Parallel?

put your 17 batch files path in a file (batchlist.txt), one in each line and run the following powershell code:
Get-Content "batchlist.txt" | %{

  # Define what each job does
  $ScriptBlock = {
    $_ #run the batch file
    Start-Sleep 60
  }

  # Execute the jobs in parallel
  Start-Job $ScriptBlock
}

Get-Job

# Wait for it all to complete
While (Get-Job -State "Running")
{
  Start-Sleep 10
}

# Getting the information back from the jobs
Get-Job | Receive-Job

Open in new window

Just create a batch file.... either run them manually in there with:


@echo off
START "BATCH1" "c:\myfolder\mybatch1.cmd"
START "BATCH2" "c:\myfolder\mybatch2.cmd"

etc.

or using a subroutine if they are all in the same dir etc.

@echo off
cd /d c:\maindir
call :runbatch BATCH1.cmd
call :runbatch BATCH2.cmd
call :runbatch c:\someotherdir\BATCH3.cmd
exit /b
:runbatch
  START "%~*" "%~*"
exit /b

Or read the names and run all in a dir...  can get fancier telling it to leave out own name etc. if needed


@Echo off
cd /d c:\batchdir
for %%a in (*.cmd) do START "%%~a" "%%~a"

The first bit in quotes on the START command is just the title of the window, second parameter is the filename to run.  Unless you add /WAIT it carries on to the next command with the batch launched in another window.

Can't do powershell or any freeware.  'start' instead of 'call' was perfect.
