如何获取包含特定搜索字符串的文件名及其句子的列表?

I tried with following command on unix machine:

我在unix机器上尝试了以下命令:

ls -l | awk '{print $9}' | xargs -I {} cat  {}  | grep {"String to search"}

Though this works with text files but when i try it with xml files it is not able to display proper grepped text.Instead it displays whole xml file.

虽然这适用于文本文件，但是当我尝试使用xml文件时，它不能显示正确的加了油的文本。相反，它显示整个xml文件。

I think the possible reason behind this is absense of new line character in xml file that i use.

我认为这背后可能的原因是我使用的xml文件中没有新的行字符。

Example: Search string: "/1031/"

示例:搜索字符串:/ 1031 /

Xml line containing search string: <eventtype uri="{any_url}/1031/"/>

包含搜索字符串的Xml行:

To clarify a bit :

澄清一点:

ls -l | awk '{print $9}' | xargs -I {} cat {} | grep -o "/1031"

ls -l | awk '{打印$9}' | xargs -I {} | grep -o "/1031"

This gives output as:

这使输出为:

/1031

/ 1031

/1031

/ 1031

/1031...

/ 1031…

I also want the name of the file in which it belongs.

我还需要它所属的文件的名称。

2 个解决方案

#1

grep has a flag -o which only outputs the matching text.

grep有一个标记-o，它只输出匹配的文本。

ls -l | awk '{print $9}' | xargs -I {} cat {} | grep -o {"String to search"}

From your edit it looks like you need the "line" that contains the URL as well. By default grep will match greedily which means a regex to account for the XML formatting will still give you an incorrect result.

从您的编辑中，看起来您还需要包含URL的“行”。默认情况下，grep将贪婪地匹配，这意味着用于解释XML格式的regex仍然会给出错误的结果。

I can think of 2 possible options:

我可以想到两种可能的选择:

For the next examples, test.xml contains the string:

对于下一个示例，测试。xml包含字符串:

<eventtype uri="{www.example1.com}/1031/"/><eventtype uri="{www.example2.com}/1031/"/><eventtype uri="{www.example3.com}/1031/"/>

The first is to use the -P flag for grep to enable perl syntax and match lazily.

第一个是使用grep的-P标志来启用perl语法并延迟匹配。

grep -Po '".*?/1031/"' test.xml

This outputs:

这个输出:

"{www.example1.com}/1031/"
"{www.example2.com}/1031/"
"{www.example3.com}/1031/"

The second is to use sed to manually append a newline after each match and pipe to grep:

第二是使用sed在每次匹配后手动添加新行，并将管道连接到grep:

sed 's/1031/1031\n/g' test.xml | grep 1031

Outputs:

输出:

<eventtype uri="{www.example1.com}/1031
/"/><eventtype uri="{www.example2.com}/1031
/"/><eventtype uri="{www.example3.com}/1031

I believe both methods should work ok on plain text files although you may need to conditionally use one of these methods on .xml extensions.

我认为这两种方法在纯文本文件上都可以工作，尽管您可能需要在.xml扩展上有条件地使用其中的一种方法。

Dear You could use below command

亲爱的你可以使用下面的命令

find -type f -exec grep -HPo '".*?/1031/"' {} \;

Sample Output

样例输出

[root@MUM03S001 ~]# find -type f -exec grep -HPo '".*?/1031/"' {} \;

[root@MUM03S001 ~]#查找-type f -exec grep -HPo '" *?/ 1031 /“{ } \;

./File:"{www.example1.com}/1031/"

/文件:“{ www.example1.com } / 1031 /”

./File:"{www.example2.com}/1031/"

/文件:“{ www.example2.com } / 1031 /”

./File:"{www.example3.com}/1031/"

/文件:“{ www.example3.com } / 1031 /”

[root@MUM03S001 ~]#

root@MUM03S001 ~ #
