I have just started trying to do some code for MS-Dos Batch files. I have written a few minor things like, returning someones text they enter. But I have been searching all over google and I can't find out how to do this:

How can I make it so every 5 minutes, the MS-Dos Batch file will check if a .exe file is running, if it is, leave it and starting counting again, and, if it isnt, start it and start counting again.

Thanks

p.s. nice christmas smilies

Hi Boylett,

Welcome to TSG !

You should first download the Windows 2003 Resource Kit from here.
There is a tool called pmon.exe that allows you to view the running processes in a DOS window.

Also, add a look to the MS-DOS at command to schedule tasks to be performed at a specified time and date.

Ok, I have downloaded the Windows 2003 Tool Kit. When I looked at pmon.exe, yes it told me which programs were running, but how would I go about doing a command which asks it whether a program is running?

[Chicon]

Example :
-------

pmon.exe > result.txt
find "your_process.exe" result.txt
if errorlevel 0 goto found
...
...
...
:found
...
...

[Boylett]

Its writes nothing to result.txt

- Dowload Process Viewer for Windows from here,

- Extract the file into a folder anywhere on your drive,

- Browse the folder and you'll see a file called pv.exe,

- Via a DOS windows : cd until you reach the folder then type pv > result.txt and you will have all the running processes in the file result.txt (it works).

The pmon.exe is aimed to build a batch file, you must trigger to show the processes.

Also, you may copy paste the pv.exe file into the folder where the MS-DOS executables are stored (C:\WINDOWS\system32 if you've a standard installation of Windows XP).

ok, still a few problems

@echo off

:BEGIN

cd G:\pv
START pv.exe

pv > result.txt

find "prog.exe" result.txt
if errorlevel 0 goto BEGIN

cd G:\

START prog.exe

goto BEGIN

if this line: if errorlevel 0 goto BEGIN is if errorlevel 1 goto BEGIN it constanly starts program, if its how it is, it never starts it. So its still not working >.<

I have tested the following code and it works :

@ECHO off

:BEGIN

%SystemRoot%\Temp\pv.exe -d10000 > result.txt

FIND "notepad.exe" result.txt
IF ERRORLEVEL 1 %SystemRoot%\system32\notepad.exe

GOTO BEGIN

The -d10000 parameter of pv.exe means a delay of 10 seconds.
After the FIND command, the test of ERRORLEVEL must be retricted to the value 1.
Indeed, the value 0 is always produced weither the string was found or not !

[Boylett]

it writes nothing to result.txt, still, so constantly starts it for me ???

[Chicon]

Duh ! My previous code seems working but in fact, it's waiting the Notepad process to be closed. Also, the delay parameter of the process viewer doesn't produce any result.

Now, I assure you the following piece of code is working : this time, I've tested it step by step and the result.txt file is not empty :

@ECHO off

:BEGIN

%SystemRoot%\Temp\pv.exe -d10000

%SystemRoot%\Temp\pv.exe > result.txt

FIND "notepad.exe" result.txt
IF ERRORLEVEL 1 START %SystemRoot%\system32\notepad.exe

GOTO BEGIN
