这是我的代码

@echo off 
setlocal enabledelayedexpansion 
REM set "string=A cat and dog had a [180.16.10.168]" 
for /f "tokens=*" %%a in ('type output.txt') do (
set line=%%a 
for /f "tokens=5" %%i in ("%line%") do set word2=%%i 
echo %word2% 
ECHO. 
echo !line! 
) 
REM start output1.txt 
pause 

我想从文件中迭代相同的IP地址后，把新线， 任何人都可以帮助我， 我工作了三天 谢谢

正如SomethingDark已经指出的那样，你非常接近。使用其他方法来提取IP（因为它不是令牌5中的每一行）和可变记住上次IP：

echo off 
setlocal enabledelayedexpansion 
(
for /f "tokens=*" %%a in (output.txt) do (
    for /f "tokens=2 delims=[]" %%i in ("%%a") do (
    if "!oldIP!" neq "%%i" (
    if defined oldip echo/ 
    set "oldIP=%%i" 
    ) 
) 
    echo %%a 
) 
)>output1.txt 
start output1.txt 
pause 

（注：你可以使用for变量（%%a）直接，没有必要!line!。
