如何用CMD读写INI文件

[yin2099]

我有一个INI文件：config.ini
[Common]
ITEM1=ITEM_1
ITEM2=ITEM_2
ITEM3=ITEM_3

1.我想读[Common]ITEM2的值，
2.重写[Common]ITEM2的值为"test2"
要怎么写这个bat文件呀

[Mirs]

VB很多这样的列子

注意：在写ini时，会清除空行和注释行。
[code=BatchFile]@echo off & setlocal enabledelayedexpansion
set "f="
set "i="
for /f "delims=" %%a in (config.ini) do (
set v=%%a
if "!v:~0,1!"=="[" (
if %%a==[Common] (set f=1) else (set "f=")
) else (
if defined f (
for %%b in (%%a) do (
if %%b==ITEM2 (set f=2) else (if !f!==2 set i=%%b&&goto readover)
)
)
)
)

:readover
if defined i (echo ITEM2=%i%)

set "f="
(for /f "delims=" %%a in (config.ini) do (
set v=%%a
if "!v:~0,1!"=="[" (
if %%a==[Common] (set f=1) else (set "f=")
echo.%%a
) else (
if defined f (
if defined i (
if "%%a"=="ITEM2=%i%" (echo ITEM2=test2) else echo.%%a
) else (
set "f="
echo ITEM2=test2
)
) else echo.%%a
)
))>config.ini2

move config.ini2 config.ini
pause[/code]

掉了一句，再发一次：
[code=BatchFile]@echo off & setlocal enabledelayedexpansion
set "f="
set "i="
for /f "delims=" %%a in (config.ini) do (
set v=%%a
if "!v:~0,1!"=="[" (
if %%a==[Common] (set f=1) else (set "f=")
) else (
if defined f (
for %%b in (%%a) do (
if %%b==ITEM2 (set f=2) else (if !f!==2 set i=%%b&&goto readover)
)
)
)
)

:readover
if defined i (echo ITEM2=%i%)

set "f="
(for /f "delims=" %%a in (config.ini) do (
set v=%%a
if "!v:~0,1!"=="[" (
if %%a==[Common] (set f=1) else (set "f=")
echo.%%a
) else (
if defined f (
if defined i (
if "%%a"=="ITEM2=%i%" (echo ITEM2=test2) else echo.%%a
) else (
set "f="
echo.%%a
echo ITEM2=test2
)
) else echo.%%a
)
))>config.ini2

move config.ini2 config.ini
pause[/code]
