Mask understanding help needed

[siteregistrator]

I'm new to this program and trying to follow article from Wiki https://www.question-defense.com/2010/08...int-attack

And I can't understand what this line do: -1 ?l?d?s?u ?1?1?1 ?1?1
As I understand -1 ?l?d?s?u defines charsets but what other two parts do? What ranges it produces?

I think that in this case, the space should have not been there. It's a simple bruteforce of 5 characters to generate candidates to process afterward so you should have read ?1?1?1?1?1. Yes, -1 ?l?d?s?u sets the charset but now you can more simply use ?a?a?a?a?a instead.

Thank you a lot

The post was written five years ago for oclHashcat v0.22. Back then oclHashcat required a left side and a right side, so the space in the mask was correct. oclHashcat is different now.
