使用BASH解析MegaCLI输出

Question

我正在使用LSI的MegaCLI命令转储我的2个RAID控制器的完整配置输出。我想解析文本文件，只打印出我感兴趣的行。例如：

"Adapter" 
"Product Name" 
"RAID Level Size State" 
"Number Of Drives" 
"Physical Disk" 
"Raw Size"
"Link Speed" 
"Media Type" 
"Drive Temperature"

但是，考虑到文件包含两个RAID控制器卡的配置数据(按降序排列)，我如何才能最好地使用BASH来完成这个任务！下面是我正在处理的输出。

注意到：我应该提到，我计划很快安装另一个RAID控制器，所以理想情况下，我希望使用类似BASH的“read”内置的东西来读取文件。这样，脚本将自动捕获新安装的RAID控制器配置数据。

Answer 1

当你说“只有巴什”的时候，你真的是认真的吗？bash本身是非常无力的；它实际上取决于拥有一组非内置命令来执行任何重要的操作。另外，你真的只是想要选择的行，还是想要重新格式化信息呢？

如果您只想要行(可能还有一些标题信息)，并且有可用的egrep，那么这很简单：

MegaCLI -whateveroptions | egrep '^(Adapter|Product Name|RAID Level Size State|Number Of Drives|Physical Disk|Raw Size|Link Speed|Media Type|Drive Temperature):`

如果您真的需要100%纯bash，可以使用read、case和echo来完成。

MegaCLI -whateveroptions | while read line; do
    case "$line" in
        Adapter:* | \
        Product Name:* | \
        RAID Level Size State:* | \
        Number Of Drives:* | \
        Physical Disk:* | \
        Raw Size:* | \
        Link Speed:* | \
        Media Type:* | \
        Drive Temperature:* )
            echo "$line" ;;
    esac
done

Answer 2

如果您对解析这些内容感到厌烦，我会考虑使用更新的LSI控制器和StorCLI64二进制文件。StorCLI有点类似于MegaCLI，但允许您将“J”附加到每个命令中，以便以JSON返回响应。
