例文：

ms_count=1
ms_1_deviceName="3ware Escalade 7000/8000 ATA RAID"
ms_1_tag="3wDrv100"
ms_1_sysFile="3wDrv100.sys"
ms_1_hwids="PCI\VEN_13C1&DEV_1001&SUBSYS_100113C1"
ms_1_isBusExtender=false
ms_1_exc_disableIfOS="w2k"


ms_count=1
ms_1_deviceName="ACARD AEC6210UF UltraDMA33"
ms_1_tag="aec6210"
ms_1_sysFile="AEC6210.sys"
ms_1_hwids="PCI\VEN_1191&DEV_0002&SUBSYS_00021191,PCI\VEN_1191&DEV_0004&SUBSYS_00041191,PCI\VEN_1191&DEV_0005&SUBSYS_00051191"
ms_1_isBusExtender=false
ms_1_exc_disableIfOS="w2k"

如用find找到“ms_1_tag="aec6210"”，如何显示这行上面的第两行呢？即“ms_1_deviceName="ACARD AEC6210UF UltraDMA33"”

@echo off
for /f "delims=:" %%a in ('findstr /n "ms_1_tag=\"aec6210\"" a.txt') do set /a n=%%a-2
for /f "skip=%n% delims=" %%a in (a.txt) do (
    if not defined n set "next=%%a" & goto echo
    if not defined last (set last=%%a) else set n=
)

:echo
echo 上一行： %last%
echo 下一行： %next%
pause

@echo off
setlocal enabledelayedexpansion
set str=ms_1_tag="aec6210"
for /f "delims=" %%a in (a.txt) do (
    if defined found set "next=%%a" & goto echo
    if "%%a"=="%str%" (set found=.) else set last=%%a
)

:echo
echo 上一行： %last%
echo 下一行： %next%
pause

上一行 grep -B 1 “aec6210” a.txt | head -1
下一行 grep -A 1 "aec6210" a.txt | head -1

谢谢楼上两位！不过哪有grep.exe下载？
