我想用sed对大型播放列表文件进行排序.每个播放列表项都有2行,所以我需要根据第一行中tvg-name =之后的字符串进行排序(所以在这种情况下,第一行将是英国：按钮1(SG))排序第一行和下一行它(以http开头的那个).
我已经看到了非常相似的正则表达式示例,但语法超出了我的逆向工程以适合我的文件.有人可以帮忙吗？

我从我的主人那里复制并粘贴了一部分电影,两个脚本都没有对输出进行更改.示例如下：
输入：
#EXTINF:-1 tvg-id="" tvg-name="The Santa Clause" tvg-logo="http://liquidit.info:8080/images/hrZjAYAF1o37k4Qb442c4yxwVLw_small.jpg" group-title=_Movies_",The Santa Clause#EXTINF:-1 tvg-id="" tvg-name="The Santa Clause 2" tvg-logo="http://liquidit.info:8080/images/i7tbiDPIaa4VsQh1wWmbkY4zTRX_small.jpg" group-title=_Movies_",The Santa Clause 2#EXTINF:-1 tvg-id="" tvg-name="The Santa Clause 3 The Escape Clause" tvg-logo="http://liquidit.info:8080/images/kvKXyrc3cUGqXin2u76Ef8lApMI_small.jpg" group-title=_Movies_",The Santa Clause 3 The Escape Clause#EXTINF:-1 tvg-id="" tvg-name="The Sapphires" tvg-logo="http://liquidit.info:8080/images/h7zn7Sf0Jl6mFZjGj4TCHjSJj6T_small.jpg" group-title=_Movies_",The Sapphires#EXTINF:-1 tvg-id="" tvg-name="Fracture" tvg-logo="http://liquidit.info:8080/images/sl5QYze20MclzdlxLDqe3sEjdiW_small.jpg" group-title=_Movies_",Fracture
由于alpabeticalised排序,预计Ouptut将成为顶部的电影项目“断裂”.

解决方法
如果你想用像sed这样的工具来做这件事,你必须要么A)相信你的字段不包含恶意的东西,比如tvg-id =“http：// …,或者B)写下非常辛苦的脚本.
我会尝试粗糙但有效的东西,就像这样.首先,将两行合并为一行：
sed 'N;s/\n//'
然后将tvg-name字段复制到该行的前面：
sed 's/\(.*tvg-name=\)\("[^"]*"\)/\2\1\2/'
然后排序：
sort
sed 's/^"[^"]*"//'
然后将一行拆分为两行：
sed 'h;s/http.*//;p;g;s/.*http/http/'
把它们放在一起：
sed 'N;s/\n//;s/\(.*tvg-name=\)\("[^"]*"\)/\2\1\2/' filename | sort | sed 's/^"[^"]*"//;h;s/http.*//;p;g;s/.*http/http/'
