grep -Ff产生无效输出 [英] grep -Ff producing invalid output

问题描述

我使用

代码 -

  grep  - Ff list.txt C：/ data / *。txt> found.txt 
  

但它会持续输出无效的回复，行不包含我输入的电子邮件。

list.txt包含 -

  [e-mail] 
 [e-mail] 
 [e-mail] 
 [e-mail] 
 [e-mail] 
  

等等。电子邮件在每一行上匹配，

搜索文件包含 -

  user1：phonenumber1：[e-mail]：last-active：recent 
 user2：phonennumber2：[e-mail]：last- active：inactive 
 user3：phonenumber3：[e-mail]：last-active：never 
  

然后另一个可能包含 -

  blublublu [e-mail]电话号码订阅
 nanananana [e-mail]电话号码退订
 useruser [e-mail]电话号码未决
  

m试图做的是将grep与电子邮件/字符串列表list.txt一起呈现，然后搜索为每个字符串匹配提供的目录并输出包含每个匹配的整行。

在这种情况下，输出的例子是 -

  user1：phonenumber1：[e-mail] ：最近活动：最近
 user2：phonennumber2：[e-mail]：最后活动：不活动
 blublublu [e-mail] phonenumber认购
 nanananana [e-mail] phonenumber取消订阅
  

但它不会输出其他两行 -

  user3：phonenumber3：[e-mail]：last-active：never 
 useruser [e-mail] phonenumber pending 
  

因为没有字符串在该行内。

解决方案

<我认为你的文件 list.txt 可能有空行在它中，使它匹配用 C：/ data / *。txt 指定的文件中的每一行。要解决您的问题，您可以手动删除每一个空行或运行命令 sed -i'/ ^ $ / d'list.txt 其中 -i 标志编辑文件到位。

这个问题也可能与dos回车有关，试试运行： cat -v list.txt 并检查行是否跟着 ^ M ：

  [e-mail] 
 [e-mail] 
  

如果是这种情况，您需要使用 dos2unix 或 tr -d'\r' < list.txt> output.txt 。

I'm using

code -

 grep -Ff list.txt C:/data/*.txt > found.txt

but it keeps outputting invalid responses, lines don't contain the emails i input..

list.txt contains -

[e-mail]
[e-mail]
[e-mail]
[e-mail]
[e-mail]

and so on.. email to match on each line,

search files contain -

user1:phonenumber1:[e-mail]:last-active:recent
user2:phonennumber2:[e-mail]:last-active:inactive
user3:phonenumber3:[e-mail]:last-active:never

then another may contain -

blublublu         [e-mail]         phonenumber         subscribed
nanananana        [e-mail]      phonenumber         unsubscribed
useruser          [e-mail]       phonenumber      pending

so what I'm trying to do is present grep with a list of emails/list of strings " list.txt " and to then search the directory provided for matches of each string and output the entire line that contains each match.

example of output in this case would be -

user1:phonenumber1:[e-mail]:last-active:recent
user2:phonennumber2:[e-mail]:last-active:inactive
blublublu         [e-mail]         phonenumber         subscribed
nanananana        [e-mail]      phonenumber         unsubscribed

yet it wouldn't output the other two lines -

 user3:phonenumber3:[e-mail]:last-active:never
 useruser          [e-mail]       phonenumber      pending

because no string is within that line.

解决方案

I think your file list.txt may have blank lines in it, causing it to match every line in the files specified with C:/data/*.txt. To fix you can either manually delete every empty line or run the command sed -i '/^$/d' list.txt where the -i flag edits the file in place.

The issue may also be related to dos carriage returns, try running: cat -v list.txt and checking if the lines are followed by ^M:

[e-mail]^M
[e-mail]^M

If this is the case you will need to amend the file using either dos2unix or tr -d '\r' < list.txt > output.txt.
