complex regex

[delanym]

I can do ^[0-9][0-9][0-9][0-9][0-9]*\.md$ but with ^[0-9]{4,5}\.md$ I get a "Unclosed counted closure near index" error

To fix the error, you can try escaping the curly braces with backslashes (\{ and \}) like this: ^[0-9]\{4,5\}\.md$. This will ensure that the curly braces are treated as literal characters and not as part of the regex syntax.

Here's the updated regex pattern: ^[0-9]\{4,5\}\.md$

@hiteshbedre what kind of string do you think I'm trying to match?
