尾巴使用Grep:过滤一定没有。当grep

标签: grep tail

让我们说,我想使用字符串" xyz" grep一个日志文件。如下。

tail -f filename | grep -vw" xyz"

在这种情况下" xyz"是我要搜索的关键字。这将过滤日志文件中的行,这些行的单词匹配" xyz"。

我还希望在日志文件中匹配关键字" xyz"时,从日志文件中过滤掉接下来的10行。我怎样才能做到这一点?

请帮忙!

您可以使用sed来实现此目的。

使用awk的另一种方法:

tail -f filename | awk 'BEGIN{skip=-1}/xyz/{skip=NR+10}NR>skip{print}'
