找出批处理文件运行的父进程数

标签: windows batch-file cmd process pid

我有一个在多个CMD会话中调用自己的批处理文件,例如:

@echo off
if "%var%"=="set" goto :begin
set var=set
call cmd /c %0

:begin
echo Inside CMD session! Executed under x processes
pause

我想要完成的是获取正在调用批处理文件的进程数。

正常批处理文件:

| Batch-file
   | Batch script

将返回1,因为正在从根进程调用批处理文件

多个流程批处理文件:

| Batch-file
   | CMD
      | Batch-file
         | Batch script

将返回2,因为正在从另一个批处理文件调用批处理文件。

一个可能的解决方案是获取根进程标识号(PID),然后分析该进程的等待链,我可以在任务管理器中轻松完成:

Wait chain, Task Manager

要点: 如何在有或没有任何第三方实用程序的情况下返回正在执行批处理文件的进程数?

@echo off
setlocal

if "%var%"=="3" goto :begin
set /A var+=1
cmd /C "%~F0"
goto :EOF

:begin
echo Inside CMD session!

wmic process where "name='cmd.exe'" get ExecutablePath,ParentProcessId,ProcessId > wmic.txt
for /F "skip=1 tokens=1-3" %%a in ('type wmic.txt') do (
   ECHO %%a - Parent: %%b - PID: %%c
   set "Parent[%%c]=%%b"
   set "This=%%c"
)

set X=0
:nextParent
   set /A X+=1
   call set "This=%%Parent[%This%]%%"
if defined Parent[%This%] goto nextParent
echo Executed under %X% processes

输出示例:

Inside CMD session!
C:\Windows\system32\cmd.exe - Parent: 3792 - PID: 4416
C:\Windows\system32\cmd.exe - Parent: 4416 - PID: 3220
C:\Windows\system32\cmd.exe - Parent: 3220 - PID: 1728
C:\Windows\system32\cmd.exe - Parent: 1728 - PID: 3560
Executed under 4 processes

我涉足Aacini的代码,让树更具视觉效果

Inside CMD session
C:\WINDOWS\system32\cmd.exe - 1004:12424
C:\WINDOWS\system32\cmd.exe -      12424:12016
C:\WINDOWS\system32\cmd.exe -           12016:10592
C:\WINDOWS\system32\cmd.exe -                10592:11392
C:\WINDOWS\system32\cmd.exe -                     11392:5616
Executed under 5 processes

更改了中间部分

Set "Space="
wmic process get ExecutablePath,ParentProcessId,ProcessId > wmic.txt
for /F "tokens=1-3" %%a in ('type wmic.txt') do (
   if /I "%%a" equ "%ComSpec%" (
      Call ECHO %%a - %%Space%%%%b:%%c
      CAll Set "Space=%%Space%%     "
      set "Parent[%%c]=%%b"
      set "This=%%c"
   )
)

@echo off
setlocal

if "%var%"=="3" goto :begin
set /A var+=1
cmd /C "%~F0"
goto :EOF

:begin
echo Inside CMD session!
set /p Space=

wmic process get ExecutablePath,ParentProcessId,ProcessId > wmic.txt
for /F "tokens=1-3" %%a in ('type wmic.txt') do (
   if /I "%%a" equ "%ComSpec%" (
      Call ECHO %%a - %%Space%%%%b:%%c
      CAll Set "Space=%%Space%%     "
      set "Parent[%%c]=%%b"
      set "This=%%c"
   )
)

set X=0
:nextParent
   set /A X+=1
   call set "This=%%Parent[%This%]%%"
if defined Parent[%This%] goto nextParent
echo Executed under %X% processes
pause
