与SED匹配WebVTT文件中的时间戳
我有以下可匹配和删除.webvtt字幕文件（YouTube的默认值）中的PCRE2 REGEX：
^[0-9].:[0-9].:[0-9].+$
这更改了：
00:00:00.126 --> 00:00:10.058
How are you today?
00:00:10.309 --> 00:00:19.272
Not bad, you?
00:00:19.559 --> 00:00:29.365
Been better.
我
How are you today?
Not bad, you?
Been better.
如何将此PCRE2 REGEX转换为惯用性）等效于sed的正则味道？
I have the following PCRE2 regex that works to match and remove timestamp lines in a .webVTT subtitle file (the default for YouTube):
^[0-9].:[0-9].:[0-9].+$
This changes this:
00:00:00.126 --> 00:00:10.058
How are you today?
00:00:10.309 --> 00:00:19.272
Not bad, you?
00:00:19.559 --> 00:00:29.365
Been better.
To this:
How are you today?
Not bad, you?
Been better.
How would I convert this PCRE2 regex to an idiomatic (read: sane-looking) equivalent for sed's flavour of regex?

使用
sed或，不匹配以整数结尾的行
Using your regex with
sedOr, do not match lines that end with an integer
您的模式不是特定的PCRE2模式，仅使用SED，您必须逃脱
\+将其作为1次或更多次的量词。在您使用点匹配任何字符（并查看示例数据）的位置上，也有一个数字。
您可以使模式更具体，并完全省略量词。如果图案匹配，只需防止线打印即可。
-n防止SED！P在模式不匹配输出的情况下打印行的默认打印
Your pattern is not a specific PCRE2 pattern, only using sed you have to escape the
\+to make it a quantifier for 1 or more times.At the positions that you use a dot to match any character (and looking at the example data) there is a digit as well.
You could make the pattern a bit more specific, and omit the quantifier at all. Just prevent the line from printing if the pattern matches.
-nprevents the default printing in sed!pprints the line if the pattern does not matchOutput
