Question

按照上一个问题grep if the next X lines doesn't contain a specific string 我希望得到帮助，以使awk更简单。

给出以下日志：

我喜欢按以下条件过滤的awk代码：
1.行以数字开头。
2.包含：＆＃34;超时失败＆＃34;或＆＃34;连接泄漏检测＆＃34;或者＆＃34;警告＆＃34;
3.不包含EAgent（排除 - 即使包含WARN或来自＃2的其他术语）

通过这种方式，不需要在公式中添加INFO和DEBUG以及其他不相关的日志行 - 它将被自动忽略。
（只搜索我们需要的东西，而不是我们不需要的东西......）

输出应该只显示第二个WARN堆栈跟踪而没有＆＃34; EAgent＆＃34;：

        2018-04-04 05:58:16,814 [DBPool housekeeper] WARN  com.zaxxer.hikari.pool.ProxyLeakTask - Connection leak detection triggered for com.mysql.jdbc.JDBC4Connection@45df031, stack trace follows

请您试着跟随并告诉我这是否对您有帮助。

~/.ssh/id_rsa.pub

现在也添加非单线形式的解决方案。

ssh -Tv git@gitlab.com

说明： 现在也要添加代码说明，以便全面了解和学习。

awk '{line=$0;gsub(/^ +/,"")} /^[0-9]+/{flag=""} /^[0-9]+/ && (/WARN/ || /Timeout failure/ || /Connection leak detection/){flag=1;if(val && val !~ /EAgent/){print val};val=""}  flag{val=val?val ORS line:line} END{if(val){print val}}' Input_file

如果下一行X行不包含特定字符串，则awk搜索字符串
