regex - 使用sed over SSH使用正则表达式从文件中删除文本

Question

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/javascript
                  AddOutputFilterByType DEFLATE application/json
                  AddOutputFilterByType DEFLATE application/atom+xml
                  AddOutputFilterByType DEFLATE application/rdf+xml
                  AddOutputFilterByType DEFLATE application/rss+xml
                  AddOutputFilterByType DEFLATE application/vnd.ms-fontobject
                  AddOutputFilterByType DEFLATE application/x-font
                  AddOutputFilterByType DEFLATE application/x-font-opentype
                  AddOutputFilterByType DEFLATE application/x-font-otf
                  AddOutputFilterByType DEFLATE application/x-font-truetype
                  AddOutputFilterByType DEFLATE application/x-font-ttf
                  AddOutputFilterByType DEFLATE application/x-font-woff
                  AddOutputFilterByType DEFLATE application/x-javascript
                  AddOutputFilterByType DEFLATE application/xhtml+xml
                  AddOutputFilterByType DEFLATE application/xml
                  AddOutputFilterByType DEFLATE font/opentype
                  AddOutputFilterByType DEFLATE font/otf
                  AddOutputFilterByType DEFLATE font/truetype
                  AddOutputFilterByType DEFLATE font/ttf
                  AddOutputFilterByType DEFLATE image/svg+xml
                  AddOutputFilterByType DEFLATE image/x-icon
                  AddOutputFilterByType DEFLATE text/css
                  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:

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 :)

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。
