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。我想解析文本文件并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，鉴于该文件包含2个RAID控制器卡的配置数据，降序，我将如何使用ONLY BASH最好地完成此任务！以下是我正在处理的输出。
注意：我应该提一下，我计划很快安装另一个RAID控制器，所以理想情况下我想要使用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。

当你说“ONLY BASH”时，你真的是这个意思吗？ bash本身很无能为力;它真的取决于有一组非内置命令可用于做任何重要的事情。此外，你真的只想要选择的行，或者你想重新格式化信息吗？
如果您只想要线条（可能还有一些标题信息）并且egrep可用，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):`
如果您确实需要100％纯粹的bash，则可以使用read，case和echo执行此操作：
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

如果你厌倦了解析这些东西，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，但允许您在每个命令中附加“J”以使JSON返回响应。
