Download all playlist that title contains a string

[hollysheep]

Hi,

i want to download all playlist of a channel with a specific string in the title. the complete playlist title changes, but all of them includes a string. i tried this

youtube-dl --dateafter 20180928 --match-filter "playlist_title = 'specific | string'"

This only works when the playlist title is exactly "specific | string". when the title is "a specific | string" it doesn't work. i tried something like '=' or '' but both doesn't work. how can i download all playlist that have a specific string in the name?

@hollysheep I think you're matching literally the string "specific | string".
You should be using

--match-title REGEX
              Download only matching titles (regex or caseless sub-string)
