记一次数据处理的过程

Posted 2020-08-17

    由于所在公司是主要做短信行业，平时和手机号码打交道较多，各种奇葩需求也比较多，近期接到一个一个总监的奇葩需求，就是将两个文件中相同的手机号码弄处理，由于编程水平以及excel玩的有限，所以只能自己想其他额办法解决，首先每个文件有好几个字段，不过全是结构化数据，格式如下：

15994710001,2016/11/3 0:24,53100010
15994710001,2016/11/3 0:24,53100010
15001313373,2016/11/3 3:39,53100010
13937713309,2016/11/3 6:16,53100010
13758943333,2016/11/3 7:19,53100010
13868044333,2016/11/3 8:33,53100010
13500732333,2016/11/3 10:29,53100010
13523072333,2016/11/3 10:30,53100010
15138132777,2016/11/3 10:31,53100010
13960985779,2016/11/3 10:45,53100010
此文件有4000多行，
文件2 字段比较多，恰好一部分内容乱码，所以也算保护个人隐私吧。

处理的思路：

由于只是要相同的号码，所以就在linux下用一些文本处理工具对其处理，先将其处理成只含手机号码的文件，然后再做其他的处理

可以用cut或者awk截取相关的列，但是由于awk不是太熟悉，这里就使用cut截取，注意分隔符以及相关的第几列就可以。

然后可以用grep  比较，也试过diff,但是效果

1、统计两个文本文件的相同行

grep -Ff file1 file2

2、统计file2中有，file1中没有的行 比较两个不同的行

grep  -vFf  file2 file1
