more batch file help

[agidius]

this week, I discovered that if 4 instances of mencoder are running at a time, the server decides to clock out and go home.
not everything I record is transcoded, but this week there was a marathon of shows that are.

how can I have the batch file check to see if it is already running??
I want to have the batch file check to see if mencoder.exe is running as a process.
if it is, I want it to wait a certian amount of time and check again.

just for kicks, here is my current postprocessing.bat

Code:

@echo off
cd c:\program files\devnz\gbpvr
sleep.exe 120

rem adds recorded show to RECORDED list
rectracker %1
sleep.exe 5

rem removed pending shows that are on RECORDED list
rectracker -purge
sleep.exe 5

rem ---------------------------------------------------

rem Checks available diskspace on the recordings drive and sends text message to my phone if it gets too low
cd c:\program files\devnz\gbpvr\disklimit
disklimit.exe -disk f -limit 25gb -messagefile PVRmessage.txt

rem ---------------------------------------------------

cd c:\program files\devnz\gbpvr

rem get first 8 letters of filename
SET RECORDING=%~n1
SET SHOW=%RECORDING:~0,8%

rem sends file to appropriate commands based on first 8 of filename
IF "%SHOW%"=="Battlest" GOTO GALACTICA
IF "%SHOW%"=="It Takes" GOTO THIEF
IF "%SHOW%"=="The Sara" GOTO SARAH
IF "%SHOW%"=="Bullrun_" GOTO BULLRUN
rem IF "%SHOW%"=="Planet E" GOTO PLANET

rem If none are true, Batch exits
GOTO END

SysInternals (now acquired by MS) has many batch file tools that can provide advanced functionality in batch file programming. (http://www.microsoft.com/technet/sysinte...fault.mspx)

The one in particular you need for this is called PsList.exe and can be found in the Process Utilities sub-section. It will list all the current processes running on your system.


Here is an example of a batch file that will test if a process is running or not.

@Echo off
pslist 2>NUL | findstr "%1" 2>&1 NUL
if %ERRORLEVEL% == 0 (
echo %1 is running
) else (
echo %1 is NOT running
)
