Sublime 正则表达式应用：日志信息过滤_sublime过滤

工具：Sublime

需求：生产环境由于程序BUG导致业务数据错乱，需要找出受影响的表及所有关联表并对数据恢复。由于日志文件50MB几十几百万行，所以迫切需要筛选出所有相关日志。

日志文件：system.log

1. 过滤出包含指定业务数据【1541403331278483474】的日志行

    逆向思维：使用下面的正则表达式，找出不包含【1541403331278483474】的行，删除掉（正则替换为空字符串）。

^(?!.*1541403331278483474).*$

2. 正则替换空白行：

^(\t)*$\n

3. 留下的行就是受影响的表
