GREP REGEX大文件 [英] GREP REGEX LARGE FILE

问题描述

在MAC上，我该如何GREP？我有一个大的TXT文件（200MB）。样本数据如下。我想用一个正则表达式运行一个GREP，并且能够在我的终端响应中获得以下数据值：

lockquote
00424730350000190100130JEAN DANIELE&

我希望一切高达 82700 。一旦获得这些信息，我可以将其复制到另一个文件中用于其他目的。现在我刚收到大量信息。

样本记录：

00424730350000190100130JEAN DANIELE& 82700 TINEPORK CT LAT BORAN AK 12345 3342843470224201400003980000002664300001216IWD QD0415200800004005880002281300000671IWD QM0330200500004900000001836800000431IWD QM0325199900002455270001147700000969IWD QM

样本Grep我写道：

  grep -E^（。*？）82700MYFILE.TXT 
 grep -E^（。*？）[0-9]MYFILE .TXT 
  

这仍然不起作用，它会返回吨信息和 82700 可以是任何值...我希望它是任何帮助建议？谢谢

解决方案

对于示例数据

  grep -E -o^ [0-9] {23} [^ 0-9] + [0-9] +MYFILE.TXT 
  

似乎可以胜任这项工作：

00424730350000190100130JEAN DANIELE& 82700

使用 Darwin 14.4.0上的grep（BSD grep）2.5.1-FreeBSD 。

请评论，如果并且需要调整/进一步的细节。

On a MAC how do I GREP? I have a large TXT file (200MB). The sample data is below. I want to run a GREP with a regex and be able to get ONLY the following data values in my terminal response:

00424730350000190100130JEAN DANIELE &

I want everything up to 82700. Once I have this information, I can copy it into another file for other purpose. Now I just get back tons of information.

Sample Record:

00424730350000190100130JEAN DANIELE & 82700 TINEPORK CT LAT BORAN AK 12345 3342843470224201400003980000002664300001216IWD QD0415200800004005880002281300000671IWD QM0330200500004900000001836800000431IWD QM0325199900002455270001147700000969IWD QM

sample Grep I wrote:

grep -E "^(.*?)82700" MYFILE.TXT
grep -E "^(.*?)[0-9]" MYFILE.TXT

This still doesn't work, it gives back tons of info and the 82700 can be any value...I would like it to be Any help suggestions? thank you

解决方案

For the sample data

grep -E -o "^[0-9]{23}[^0-9]+[0-9]+" MYFILE.TXT

seems to do the job:

00424730350000190100130JEAN DANIELE & 82700

using grep (BSD grep) 2.5.1-FreeBSD on Darwin 14.4.0.
