Question

我有一个简单的邮件，我需要删除Summary of client activity for the last 24 hours之前的所有内容我认为它最适合sed。

我搜索了互联网，但它只是用分隔符或类似的东西。

你有什么想法吗？

邮件的一部分：

The following clients have no associated schedule
NodeDomainContact
-KABA-FILESYSTEM-
-USTICA-FILESYSTEM-

Summary of client activity for the last 24 hours

-FILESYSTEM-ABSYNTHE-Linux x86-64-XFS-

期望的输出：

Summary of client activity for the last 24 hours
DomainNodenamePlatformTypeActivityData amountElapse timeAffectedFailedMedia     wait
-FILESYSTEM-ABSYNTHE-Linux x86-64-XFS-

Answer 1

很容易：

awk '/Summary of client activity for the last 24 hours/{p=1}p' file

或sed：

sed -n '/Summary of client activity for the last 24 hours/,$p' file

使用awk的电子邮件示例进行测试（上面的sed cmd具有相同的输出）：

kent$  cat f

Answer 2

您可以使用sed地址范围不打印从第一个到模式的所有行

$ sed -n '1, /Summary of client activity for the last 24 hours/!p;
DomainNodenamePlatformTypeActivityData amountElapse timeAffectedFailedMedia     wait
-FILESYSTEM-ABSYNTHE-Linux x86-64-XFS-
BACKUP-

00:00-

...

要包含Summary...行，

$ sed -n '1, /Summary of client activity for the last 24 hours/!p; /Summary of client activity for the last 24 hours/p' test
Summary of client activity for the last 24 hours
DomainNodenamePlatformTypeActivityData amountElapse timeAffectedFailedMedia     wait

SED在字符串之前删除所有内容
