我试图通过SSH使用sed命令从文件中删除文本。该命令是:

sed -i -r '/(\#\#Some\ text\ domain\.com\ some\ text)((.*?(\n))+.*?)(\#\#Some\ text\ domain\.com\ some\ text)/d' file

该文件中包含以下文本: 
##Some text domain.com some text 
                <IfModule mod_expires.c> 
                ExpiresActive On 
                ExpiresByType image/jpg "access 1 month" 
                ExpiresByType image/jpeg "access 1 month" 
                ExpiresByType image/gif "access 1 month" 
                ExpiresByType image/png "access 1 month" 
                ExpiresByType image/svg "access 1 month" 
                ExpiresByType text/css "access 1 month" 
                ExpiresByType text/html "access 1 month" 
                ExpiresByType application/pdf "access 1 month" 
                ExpiresByType text/x-javascript "access 1 month" 
                ExpiresByType text/javascript "access 1 month" 
                ExpiresByType application/javascript "access 1 month" 
                ExpiresByType application/xhtml+xml "access 1 month" 
                ExpiresByType application/x-shockwave-flash "access 1 month" 
                ExpiresByType image/x-icon "access 1 month" 
                ExpiresDefault "access 1 month" 
                </IfModule> 
 
               <ifModule mod_headers.c> 
                  <filesMatch ".(css|jpg|jpeg|png|gif|swf|svg|js|ico)$"> 
                    Header set Cache-Control "max-age=2592000, public" 
                 </filesMatch> 
                  <filesMatch ".(x?html?|php)$"> 
                    Header set Cache-Control "private, must-revalidate" 
                 </filesMatch> 
                </ifModule> 
 
                <IfModule mod_deflate.c> 
                  # Compress HTML, CSS, JavaScript, Text, XML and fonts

                  AddOutputFilterByType DEFLATE application/xml

                  AddOutputFilterByType DEFLATE font/ttf 
                  AddOutputFilterByType DEFLATE image/svg+xml

                  AddOutputFilterByType DEFLATE text/html 
                  AddOutputFilterByType DEFLATE text/javascript 
                  AddOutputFilterByType DEFLATE text/plain 
                  AddOutputFilterByType DEFLATE text/xml 
                </IfModule> 
                ##Some text domain.com some text

我使用了下一个工具来验证我的常规技能:

https://regex101.com/

并确认同样有效，因此我想问题出在sed命令中。任何想法都非常感谢!

先感谢您 :)

请您参考如下方法:

由于您编写了可工作的PCRE / Perl兼容表达式，因此将其与perl结合使用:

perl -0777 -i 's/(\#\#Some\ text\ domain\.com\ some\ text)((.*?(\n))+.*?)(\#\#Some\ text\ domain\.com\ some\ text)//g' file
也就是说， -0777将文件压缩为单个文本，其中换行符可以与regex模式匹配， -i将内联更改， s中的 s/表示替换，该模式是regex101.com上的工作模式，并且替换模式为空。 g表示替换所有匹配项。
