如何在一個變量存儲指令的結果蝙蝠腳本

Question

FOR /F "tokens=1 delims=" %%A in ('netstat -ano | findstr 7001') do SET myVar=%%A 
echo %myVar% 

司令部說，它不findstr之前承認|，任何人都可以幫助我在這裏。

Answer 1

@echo off 
set portnumber=? 

FOR /F "tokens=1,2,3,4,* delims= " %%a in ('netstat -ano') do call :handleline %%a %%b %%c %%d %%e 

goto :eof 

:handleLine 
call :portcheck %1 %2 %2 %4 %5 

rem you can have your check here 
rem if %portnumber%==7001 do whatever 
echo pid %4 uses port %portnumber% 

goto :eof 

:portcheck 
set prot=%1 
set ipandport=%2 
set pid=%4 

set pn1=%ipandport:~-1% 
set pn2=%ipandport:~-2% 
set pn3=%ipandport:~-3% 
set pn4=%ipandport:~-4% 
set pn5=%ipandport:~-5% 

if !%pn2:~0,1%!==!:! set portnumber=%pn1% & goto :bailout 
if !%pn3:~0,1%!==!:! set portnumber=%pn2% & goto :bailout 
if !%pn4:~0,1%!==!:! set portnumber=%pn3% & goto :bailout 
if !%pn5:~0,1%!==!:! set portnumber=%pn4% & goto :bailout 
set portnumber=%pn5% 
:bailout 

goto :eof 

Answer 2

特殊字符如|必須在IN（）子句內轉義或引用。請注意，不需要TOKENS = 1選項 - 這是默認值。

您可以使用

for /f "delims=" %%A in ('netstat -ano ^| findstr 7001') do set myVar=%%A 

或

for /f "delims=" %%A in ('"netstat -ano | findstr 7001"') do set myVar=%%A
