Question

我正在尝试使用FOR命令来获取多次运行的程序的PROCESS ID。当我使用以下命令时，我可以看到3个PID

C:\>wmic PROCESS where "Name='notepad.exe'" get ProcessID | findstr [0-9]

输出： C：＆GT;

396

13928

20424

但是当我在FOR命令中的相同命令中使用它时，我只获得最后一个PID 20424的回声输出。我试图搜索notepad.exe（或任何其他程序）的PID打开，看看它是否在procdump命令中使用，如果不是我想用新的PID执行procdump。

脚本

@echo on
for /f "TOKENS=1" %%x in ('wmic PROCESS where "Name='notepad.exe'" get ProcessID ^| findstr [0-9] ^|find /v /c "notepad.exe"') do set myPID=%%x
echo %myPID%

:loop1
if /I %myPID% geq 0 (
for /f "TOKENS=1" %%a in ('wmic PROCESS where "Name='notepad.exe'" get ProcessID ^| findstr [0-9]') do set nPID=%%a 
 echo %nPID%
 echo nPID %npid%
 for /f "tokens=8" %%b in ('wmic PROCESS where "Name='procdump.exe'" get CommandLine ^| findstr %npid%') do (
  set dpid=%%b
  echo dPID %dpid%
  if %npid% neq %dpid% (
   start /B C:\Users\RV017019\Downloads\Procdump\procdump -c 1 -s 5 -n 5 %npid%
   )
  )
 )
 goto :loop1
)

输出：

C:\>for /F "TOKENS=1" %x in ('wmic PROCESS where "Name='notepad.exe'" get ProcessID | findstr [0-9] |find /v /c "note
pad.exe"') do set myPID=%x

C:\>set myPID=3

C:\>echo 3
3

C:\>if /I 3 GEQ 0 (
for /F "TOKENS=1" %a in ('wmic PROCESS where "Name='notepad.exe'" get ProcessID | findstr [0-9]') do set nPID=%a
 echo 20424

*你可以看到它正在拿起最后一个PID

 if 20424 EQU 396 (echo "you are right" 20424  )  else (echo "Not right" )
 goto :loop1
)

C:\>set nPID=396

C:\>set nPID=13928

C:\>set nPID=20424
20424
"Not right"

C:\>if /I 3 GEQ 0 (
for /F "TOKENS=1" %a in ('wmic PROCESS where "Name='notepad.exe'" get ProcessID | findstr [0-9]') do set nPID=%a
 echo 20424
 if 20424 EQU 396 (echo "you are right" 20424  )  else (echo "Not right" )
 goto :loop1
)

C:\>set nPID=396

C:\>set nPID=13928

C:\>set nPID=20424
20424
"Not right"

我想要每个PID并搜索procdump命令，如果它不存在我执行新的procdump命令。

Answer 1

尝试将回声包含在for语句中（您必须使用延迟扩展）：

setlocal enabledelayedexpansion
for /f "TOKENS=1" %%x in ('wmic PROCESS where "Name='notepad.exe'" get ProcessID ^| findstr [0-9] ^|find /v /c "notepad.exe"') do (
  set myPID=%%x
  echo !myPID!
)

Answer 2

你可以这样做：

@echo off

for /f "delims=" %%a in ('wmic PROCESS where "Name='notepad.exe'" get ProcessID  ^|findstr [0-9]') do (
    call:test %%a)
exit/b

:test
echo Testing PID : %1
if %1==396 echo Do  something with %1
if %1==13928 echo Do  something with %1
if %1==20424 echo Do  something with %1

Answer 3

以下是获取每个PID的方法：

@echo off
for /f "tokens=2 delims=<>" %%x in ('wmic PROCESS where "Name='notepad.exe'" get ProcessID /format:htable ^| find "<div" ') do call :label "%%x"
pause
goto :EOF
:label
echo %~1

Answer 4

经过几次尝试，我能够拉出这个能够做我想做的剧本。如果有人能帮助改进，那就太棒了.-谢谢

@echo off

for /f "TOKENS=1" %%x in ('wmic PROCESS where "Name='firstnet.exe'" get ProcessID ^| findstr [0-9] ^|find /v /c "firstnet.exe"') do set myPID=%%x
echo %myPID%

:loop1
if %myPID% geq 0 (

FOR /f "TOKENS=1" %%a in ('wmic PROCESS where "Name='firstnet.exe'" get ProcessID ^| findstr [0-9]') do (
set /A npid=%%a
call:test %%a

)
goto :loop1
)
exit /b

:test
  for /f "tokens=8" %%b in ('wmic PROCESS where "Name='procdump.exe'" get CommandLine ^| findstr %npid%') do set ppid=%%b
if [%1] EQU [] ( set ppid=00 ECHO Value Missing
 )
  if /I %npid% NEQ %ppid% ( 
  start procdump -c 10 -n 100 -s 3 %npid%
    ) ELSE (
  echo THIS PID %npid% PROCDUMP RUNNING
  )
timeout /t 5

Batch FOR命令ECHO命令仅显示输出的最后一行
