由于一个文本的一行很难定位，行数可能随时会变，但此行始终在某行的下面，
比如1.txt:
ppppp(此行内容固定)
asdad(此行内容不固定，且需要替换)
想把PPPPP下面那行替换成qqqqq该如何实现

@echo off
for /f "delims=" %%a in (1.txt) do (
set /a n+=1
>>1_new.txt echo %%a
if "%%a" equ "ppppp" goto next
)
:next
set /a n+=1
>>1_new.txt echo qqqqq
>>1_new.txt more +%n% 1.txt
move /y 1_new.txt 1.txt
