例文：
[3C]
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"
[A]
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"”

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