搜索和删除匹配模式前后的行

Seach and delete lines before and after a matching a pattern

输入包含由 { 和 } 框起来的日历条目, 我想删除所有 Mozilla 创建的条目,如下所示,并将结果保存在一个新文件中。

        { 
                       "c_content" = "BEGIN:VCALENDAR 
    PRODID:-//Mozilla.org/NONSGML Mozilla Calendar V1.1//EN 
    VERSION:2.0 
    BEGIN:VTIMEZONE     
    ..
    END:VCALENDAR"; 
                       "c_name" = "0000000-0000-000-0000-00000000000.ics"; 
                   },

一个日历条目的内容总计为 39 行。

gawk 'BEGIN{RS=ORS="};"}/Mozilla.org\/NONSGM/;END{printf "\n"}' inputfile

这会过滤掉所有匹配的条目,但我会得到相反的结果(比如 grep -v)。

 Input sample:

包含该行的第二个日历条目 "PRODID:-//Mozilla.org/NONSGML Mozilla Calendar V1.1//EN" 应该过滤掉。

建议 awk 个脚本:

脚本 1,基于计数线。假设每条记录长 36 行

awk '{--skip}/Mozilla.org/{skip=36}skip<1{print}' input.txt

关心第一个记录 2 行头部,最后一个记录 34 行尾部。

脚本 2,假设记录边距为 }, 。假设每条记录以 },

结尾
awk '!/Mozilla.org/{printf "%s",[=11=] RT}' RS="[[:space:]]*},"  input.txt

注意最后一条记录的尾部。是否以},

结尾

非常感谢!遗憾的是,由于记录并非都是 36 行长,因此我尝试了脚本 2。我没有得到任何输出。当我省略“!”我确实得到了 Mozilla.org 条目,所以它似乎与“!”相反没有效果。
