SED 删除字符串之前的所有内容

Question

Summary of client activity for the last 24 hours 我有一封普通邮件，在我认为它最适合 sed之前，我需要删除所有内容。

我搜索了互联网，但它只是带有分隔符或类似的东西。

你有什么想法吗？

邮件部分：

...(Personal Part of the Email)...
...
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：

Answer 1

使用 awk：

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 测试您的电子邮件示例（上面的 sed cmd 具有相同的输出）：

kent$  cat f
