[文本处理] [已解决]如何要bat来删除文件中的特定字符串，求解

BingjianREMIX

在一个日志文件中，找到“text”并删除
要求：其它（类似于text1）保留，就是：
123.log中：text，text1，text2.
处理后123.log中:text1,text2.

:delete4
@echo off
echo What user do you want to delete:
set /p ax=
echo What the user %ax%'s password:
set /p bx=
findstr /x /c:"USER_NAME:%ax%_PASSWORD:%bx%" "urini.ini" 1>nul
if %errorlevel% equ 0 (
	findstr /v /x /c:"USER_NAME:%ax%_PASSWORD:%bx%" "urini.ini" >"urini.ini.temp"
) else (
	echo not exist "USER_NAME:%ax%_PASSWORD:%bx%"
	goto :delete4
)
move /y "urini.ini.temp" "urini.ini"
cls
echo DELETE COMPLETE!

当然也有可能log是个保留词（我不知道？）那就把log改成随便啥

写了一些代码来实现注册登录重置和删除，但是删除一直有问题，求解

:login
cd /d %~dp0
title MICRODOS LOGIN ^& REGISTER
setlocal enabledelayedexpansion
if not exist urini.ini echo. >urini.ini
cls

:users2
color 07
cls
echo.

echo.
echo 1.Login
echo.
echo 2.register

echo 3.Reset users
echo.
echo 4.delete users
echo.
set /p a=Enter you choose:
if /i "%a%"=="4" goto :delete4
if /i "%a%" equ "3" (
	del urni.ini
	echo. >urini.ini
	cls
	echo RESET COMPLETE!
	pause>nul
	goto :users2
) else if /i "%a%" equ "2" (
	call :register
	goto :users2
) else if "%a%" equ "1" (
	set /p str1=Enter the USER NAME:
	set /p str2=Enter the password:
	findstr /x /c:"USER_NAME:!str1!_PASSWORD:!str2!" "urini.ini" 1>nul && (
		cls
		color 27
		echo TRUE!
		echo Please push any key to continue!
		pause>nul
		goto :dos
	) || (
		cls
		color 47
		echo ERROR!
		echo Please push any key to continue!
		pause>nul
		goto :users2
	)
) else goto :users2

:register
cls
:str1
cls
set "str1="
set /p "str1=Enter the new user name:"
if "x%str1%" equ "x" (
    echo Invalid user name.
    goto :str1
)

:str2
cls
set "str2="
set /p "str2=Enter the new password:"
if "x%str2%" equ "x" (
    echo Invalid password.
    goto :str2
)
>>"urini.ini" echo USER_NAME:%str1%_PASSWORD:%str2%
goto :users2

:delete4
echo on
echo What user do you want to delete:
set /p ax=
echo What the user %ax%'s password:
set /p bx=
findstr /x /c:"USER_NAME:%ax%_PASSWORD:%bx%" "urini.ini" 1>nul
	for /f %%i in (urini.ini) do ( set "url=%%i"
		set url="USER_NAME:%ax%_PASSWORD:%bx%"

)<nul >>"urini(2).ini"
pause
del urini.ini
ren "urini(2).ini" "urini.ini"
cls
echo DELETE COMPLETE!
pause>nul
goto :users2

有无大佬可以完美解决，在以上的源码的前提下实现的，非常感谢

   你把xxx.log改成你的目标文件 如果文件为空会报错

    将第2、6行的log改为logg看看，或者用

powershell -c "gc 1.log | %%{$_ -replace '\btext\b'} | Set-Content 1.log"
复制代码

sed -i "/\btext\b/s///g" 1.log
复制代码

@echo off
(for /f "delims=" %%a in ('type "1.txt"^|findstr /n .*') do (
	set "str=%%a"
	setlocal enabledelayedexpansion
	set "str=!str:“text”=!"
	echo=!str:*:=!
	endlocal
))>2.txt
pause
复制代码

将文本和批处理都保存为ansi编码

这个应该是vbs，要保存为.vbs文件

但是咋样用呢

jyswjjgdwtdtj

set fso=createobject("scripting.filesystemobject")
log=fso.opentextfile("xxx.log",1).readall()
set re=new regexp
re.pattern="(\b)text(\b)"
re.global=true
fso.opentextfile("xxx.log",2).write re.replace(log,"$1$2")
