问题描述

Good day to all, 祝大家好日子

In this opportunity, I'm trying to find a bash code that allow me to extract text blocks between the same pattern and each block save to a different file. 在这个机会中，我试图找到一个bash代码，允许我在同一模式和每个块之间提取文本块保存到不同的文件。

My first approach is : 我的第一个方法是 ：

sed -n "/PATTERN/,/PATTERN/p" file.log sed -n“/ PATTERN /，/ PATTERN / p”file.log

{...and yes, into the log file, the pattern that delimit each block is the same} {...和是，在日志文件中，分隔每个块的模式是相同的}

But it only print all blocks in one stream... I want to save each block into a file. 但它只打印一个流中的所有块...我想将每个块保存到一个文件中。 But, I don't know how to make a stop in each block, save it and continue with the following block. 但是，我不知道如何在每个块中停止，保存并继续下面的块。

Thanks so much in advance for any help. 非常感谢您的帮助。

此代码应创建名为resultNUM文件，其中NUM是块的编号

awk '/PATTERN/{close("result"f);f++}{print $0 > "result"f}' file.log

这可能对你有用： 

csplit -z file '/PATTERN/' '{*}'
