找出一个批处理文件 运行 下有多少个父进程

Find out how many parent processes a batch-file is running under

我有一个在多个 CMD 会话中调用自身的批处理文件,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从中调用批处理文件的进程数。

普通批处理文件:

| Batch-file
   | Batch script

会 return 1,因为正在从根进程调用批处理文件

多进程批处理文件:

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

会 return 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符号 (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:

总结: 我如何 return 在有或没有任何第三方实用程序的情况下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

我尝试了 Aacini 的代码,使树更加直观

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

改变了中间部分

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
