Question related to the code

Hello,
Sorry bothering you by a question like that.

I was reading the code to understand how it works and uniq -3 -D is confusing because I not know this syntax. I read the manual and I can only guess -3 is related to the inputs with sort but I really not understand where it's written and how it works. Are there some docs about it or maybe a proper name how it is called so that I can look it up further?

Thanks for your help and for fslint because it helped me good for cleaning few of my hard drives.
Cheers.

fslint is old software now and was written to be
compatible with older implementations of uniq.
uniq -3 is equivalent to uniq -f 3 or uniq --skip-fields=3.

man pages generally don't document every detail,
like deprecated syntax like that.
man pages now do have a link at the end to the full documentation,
which does in this case detail this case.

I.e. the following link details this nuance:
