getting process ID of exe running in Bat File

Question

I require the Process id of the "Las2xyz" process that's being run in my bat file.

How can i achieve this? I can't use the last RUN ID or the first ID, I need the actual process ID, as there are multiple of these running at any given time and ending at any given time i cannot guessimate it.

this is my batch:

@echo off
@echo off
set PATH=C:\Windows\system32;C:\atlass\las2xyz;C:\atlass\las2xyz\bin;C:\atlass\las2xyz\lib
set TOP_HOME=%C:\atlass\las2xyz%
del dat*.xyz dat*.seg dat*.pat dat*.tmp dat*.txt test.nam
las2xyz.exe "[ flightpath 2 out 5 lasformat 1 target 0 FIXCLASS 1 step 20 unit *METRIC* fov 20.0 rollfix 1   sn_number *H68_038-003* lsystem *LIDAR_1* DESTSYS 144 minele -100.00 maxele 6000.00 hoff 0.00 eoff 0.00 noff 0.00 bootnr 13110201 leg 1]" "C:\Users\Developer-One\Desktop\las2xyz_Data\131102_003243_GPE.sdc" , "\\192.168.0.102\agis\Macquarie_Barwon_1310\Area_01\sbet_038_13110201.out" - "131102_003243_cov"

Someone show me how to do it! thank you

Solution 1

This will launch an executable and get the PID:

@echo off
for /f "tokens=2 delims==; " %%a in (' wmic process call create "notepad.exe" ^| find "ProcessId" ') do set PID=%%a
echo "%PID%"
pause

Solution 2

Use tasklist

for /f "tokens=2" %%a in ('tasklist^|find /i "Las2xyz"') do (set pid=%%a)

Solution 3

Extending foxidrive's answer to show the OP's call that requires arguments:

set "exe=las2xyz.exe"
set "arg1=[ flightpath 2 out 5 lasformat 1 target 0 FIXCLASS 1 step 20 unit *METRIC* fov 20.0 rollfix 1   sn_number *H68_038-003* lsystem *LIDAR_1* DESTSYS 144 minele -100.00 maxele 6000.00 hoff 0.00 eoff 0.00 noff 0.00 bootnr 13110201 leg 1]"
set "arg2=C:\Users\Developer-One\Desktop\las2xyz_Data\131102_003243_GPE.sdc"
set "arg3=\\192.168.0.102\agis\Macquarie_Barwon_1310\Area_01\sbet_038_13110201.out"
set "arg4=131102_003243_cov"

for /f "tokens=2 delims==; " %%A in (
  'wmic process call create '"%exe%" "%arg1%" ^, "%arg2%" "%arg3%" - "%arg4%"' ^| find "ProcessId"'
) do set "PID=%%A"
echo "%PID%"

The content of the quoted arguments can contain pretty much anything except for double quote or comma. If a comma is used between arguments then it must be escaped.

There may be another syntax that allows commas within arguments, but then it would not allow parentheses within arguments.

So what to do if your command line cannot be passed through WMIC PROCESS CALL CREATE?

There is a solution. But it is not pretty ;-) I first posted this at Escaping strings when using wmic

@echo off
setlocal enableDelayedExpansion

:: At this point you could append the new PID to the PIDs list using
::   set "PIDs=!PIDs!%PID% "
