正则表达式 – 使用sed一次排序2行

发布时间：2020-12-14 05:48:07 所属栏目：百科来源：网络整理

导读：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

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

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=)("[^"]*")/212/'

然后排序：

sort

然后删除我添加的字段：

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=)("[^"]*")/212/' filename | sort | sed 's/^"[^"]*"//;h;s/http.*//;p;g;s/.*http/http/'
