[其他] bat 如何插入换行符

chenkuan9yy

setlocal enabledelayedexpansion
set file=d:\my.ini
set "file=%file:"=%"
for %%i in ("%file%") do set file=%%~fi
echo.
set replaced=[mysqld]
echo.
set all="[mysqld] lower_case_table_names = 2"

for /f " tokens=1 delims=" %%i in ('type "%file%"') do (
    set str=%%i
    set "str=!str:%replaced%=%all%!"
        REM set str=!str: =^       
    echo !str!>>"%file%"_tmp.txt
)

my.ini 文件内容是这样的
[mysqld]
lower_case_table_names = 1

我想替换好后变成这样
[mysqld]
lower_case_table_names = 2

但是现在是这样的
[mysqld]  lower_case_table_names = 1
请问怎么 替换后能换行
