Question

我有一个日志文件，我正在编写一个脚本来执行某些操作。操作是打印日志的特定区域。

 03:19:13.4 End summary update for ads.doc.ordered.OrderDetailSummary
 03:19:13.4 Begin summary update for ads.doc.inventory.InventoryItemSummary
 03:19:33.9 CronServer:: DailyJob ads.tools.UpdateSummaries@17c5d6cf failed with exception

我想打印包含单词exception的块。从时间戳到下一个时间戳

e.g1

03:19:33.9 CronServer:: DailyJob ads.tools.UpdateSummaries@17c5d6cf failed with exception ads.util.AppError: Cannot create UnitName from keys: Each
ads.util.AppError: Cannot create UnitName from keys: Each
.....
.....
.....
.....

以及下一个时间戳，如果它更容易。

OR

e.g2

06:14:33.3 Initializing Spring framework Logs
......
......
......

java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: ads.doc.backoffice.StoreInfos

有没有办法用sed做到这一点？或任何其他想法，因为我真的很困惑。

据我所知，sed一次处理一行。

考虑搜索一行是否以此模式开头

^[0-9]{1,2}:[0-9]{1,2}:[0-9]{1,2}.[0-9]

然后与异常字匹配，在下一行再次匹配表达式后打印所有这个块。

Answer 1

关键线似乎不是以日期开头，因此您可以搜索错误条件或不以这样的日期开头的行：

egrep -i "exception|^\s" yourlog

其中“\ s”是一个空格。

或者，不以数字开头的行：

egrep -i "exception|^[^0-9]"

Answer 2

你可以说：

sed '/exception/,/^[0-9][0-9]/!d' filename

对于您的输入，它会返回：

03:19:33.9 CronServer:: DailyJob ads.tools.UpdateSummaries@17c5d6cf failed with exception
ads.util.AppError: Cannot create UnitName from keys: Each
ads.util.AppError: Cannot create UnitName from keys: Each
.....
.....
.....
.....
03:46:42.5 Periodic support request failed: ads.support.SupportException: Error opening socket: java.net.ConnectException: Connection refused

编辑：对于您的更新问题，以下内容可能对您有用：

sed -n -e :t -e '/^[0-9]/,/^[0-9]/{/^[0-9]/!{$!{N;bt}};/[Ex]xception/p;}' inputfile

Answer 3

 perl -n -e 'if ( $_ =~ /^ \d{2}:\d{2}:\d{2}\.\d/ ) { $print = 0; } if ($print || $_ =~ /exception/) { print "$_"; $print = 1 };

这样的东西应该是perl替代品。

像cat file.txt | perl ...

一样使用

Answer 4

Sed的模式范围为：http://www.grymoire.com/Unix/Sed.html#uh-29

所以你可以这样做：

 sed -n '/AppError/,/^ *[0-9]\{1,2\}:[0-9]\{1,2\}:[0-9]\{1,2\}\.[0-9]/ p' file.log

-n ...除非您明确打印，否则禁止打印您可以根据自己的喜好细化起始模式。

在你的结束模式中，你需要逃避花括号。

bash脚本，打印与特定模式匹配的多行
