Which would be the easiest way within batch file?
At the moment I'm using PsList -t and parsing the result knowing that what I'm looking for will be under cmd.exe.
Any other ideas? External tools?

See
START /?
and
TASKLIST /?
Just execute TASKLIST to see an example of its output.

I'm familiar with START and TASKLIST.But they won't help me if I want the PID that I've just started.
But what if i want to start example.exe with already running instances of example.exe.And later I want to kill only mine instance.Or watch memory usage of my instance and so on.
Even powershell/vbscript does not help much here

wmic process call create "notepad.exe" | find "ProcessId"
Now If I find out how to use other properties of process query it will be great.

and a small script :
When I find more about wmic process will try to improve this.

here's a little bit improved script (I've called mine startpid ,but the name does not really matter):
Code: Select all

call :DeQuote commandline
call :DeQuote workdir

goto :eof
)
if [%2] NEQ [] (
if not exist "%workdir%\" (
echo "directory %workdir% does not exist"
exit
)
) else (
set workdir=%~dp0
)
::this does not work good enough. If there are brackets in the parameters for loop has problems.
::for /f "usebackq tokens=2 delims=;= " %%G IN (`wmic process call create '"%commandline%","%workdir%",null' ^|find "ProcessId"`) do set /A PID=%%G
pushd %workdir%
for /f "tokens=2 delims=;= " %%G IN ('wmic process call create "%commandline%" ^|find "ProcessId"') do set /A PID=%%G
popd
if [%PID%] EQU [] (
echo process didn't start
goto :eof
) else (
echo %PID%
exit /b %pid%
)

:EchoHelp
echo starts a process and return PID
echo %~n0 command_line [work_directory]
echo %~n0 -help -will print this message
echo PID of the process will be echoed and set to the errorlevel
goto :EOF
endlocalhttps://ss64.com/nt/syntax-dequote.html
The main difference is the added workdir where the process will be started (I'm not sure how big improvement is this
)the PID will be returned as a errorlevel (is it possible to overflow errorlevel's max number allowed?(no - pid is int errorlevel is long))
As this calling of creating a process with wmic wmic process call create "calc.exe" is more popular , but
with this wmic process call create "notepad.exe","c:\",null or this wmic process call create "notepad.exe","c:\"
you can create a process in a certain directory.
The third parameter is a Win32_ProcessStartup -> https://docs.microsoft.com/en-gb/window ... 32-process
but I don't know if it can be created in a WMIC query and how can be used.
It can add more useful options -> https://docs.microsoft.com/en-gb/window ... essstartup
Any idea how this can be used (may be in powershell script it will be possible)?
Creating a process on a remote host is also possible but the processing the parameters will became a mess smile

:: Written by Frank P. Westlake, 2001.09.22, 2001.09.24
:: and modified by Simon Sheppard 2002.06.09I've added an options for execution on remote machine.Now I'm parsing also error codes and trying to give some hints.In some cases there's no error code - just a error message and it's also printed. The target executable and its parameters are now separated in two arguments.
I've added an option for recording the wmic command to xml file using wmic /RECORD swith (this was useful durring the testing).
here are the params:
-exec executable : path to executable or the executable if it's in the %PATH%
[-commandline command_line] : command line parameters
[ -workdir working_directory] : working directory.Now I'm not checking the existence of the directory because of the remote host execution.
[-host remote_host [-user user [-pass password]]] : not hard to guess
wmi has a limitation and localost can't be used with user and password.May be I should add check if the host is localhost.
[-record path_to_xml_output] : path for xml used in /RECORD switch - there you'll see the wmi command and full output
In the previous version working directory didn't worked in the wmic query because the FOR /F had eating the "," - now works fine with "^,"
(why the "," is problem for the for /f ? )
Still have a problems with brackets and double quotes in password parameter - it uses wmic /PASSWORD switch and is not parsed well.
Return codes are taken form here : https://docs.microsoft.com/en-gb/window ... 32-process
I still hadn't produced 2 and 3 . 9 is thrown only where the path does not exist on remote machine.
the PID is still stored in errorlevel
I'm still not sure if other global switches could be useful.
examples :
startpid -exec "notepad" -workdir "c:/" -record "test.xml" -commandline "/A startpid.txt"
startpid -exec "cmd" -workdir "c:/" -record "test.xml" -host remoteHost -user User (<-- without pass it will be prompted)

Yeaaaah.
I like the "&&" in the loop and argparser enhancements.
I've tested this but strangely the workdir parameter is never set (it's seems it should work).
And when script fails to create process it prints : "0 was unexpected at this time."
Also a mysterious empty Create() file is created.
I need some testing to see what's going on (for test reasons wmic /record:c:\test.xm %global_params% process call create "%exec% %commandline%"^,"%workdir% can be used")

Second. Create() file was created due to appearance of "Blah blah -> Create()" to echo command which was interpreted as attempt to write to Create() file — so I made some "circum masking" to prevent that.
Third. "0 was unexpected at this time." was caused by syntax error in if operator due to empty %PID% — curly braces solve this issue.
P.S. Have to use %errmsg:~0,1% construction in :err to prevent appearance of interpreted commands after if operator and syntax errors.

Fast initial testing:
1.When I try to set an executable with spaces in it's path it can't be found - still need dequote.At least it's easy for fix
2.Setting arguments is outside of setlocal enabledelayedexpansion scope and wmic global parameters are not cleaned ( EDIT: Aaahh with your last edit this is fixed)

Scopes can be nested, so new scope in subroutine (declared by setlocal) will have all variables of parent scope but any changes to variables will not be visible to parent scope. Conclusion: all shared variables must be defined within same scope.

Btw, npocmaka, if you can give me a list of not permitted characters for password I can make changes to :argParser so it can deal with them wink
