Question

我有一台装有hwraid（megaclisas）https://hwraid.le-vert.net/wiki/DebianPackages

的服务器

示例输出如下：

我要实现的是，如果grep Status值不等于Optimal或Online，则将其设置为grep，然后通过管道发送给电子邮件。我这里的问题是如何使用sed或awk来获取该信息。

Answer 1

这里是解决方法

data=$(mktemp)
externalprogram > $data
RESULT=$(
    grep "| RAID" $data | sed -n '/Optimal/!p'
    grep "| HDD" $data | sed -n '/Online,/!p'
)
rm $data
echo "$RESULT"

解释

grep感兴趣的行
如果未找到搜索模式，则打印

如果！=，则从输出/文件中提取值并通过管道传递到电子邮件
