New to forum - assistance with reject plains
Good day all, 

Going through the documentation and building my knowledge on the tool. If anyone can help, I am trying to exclude the password from a dictionary that is numbered. For example, 88003344.

I have completed my command as follows but I am stuck. 

hashcat -m 2500 -a 0 5C.hccapx /dic-v2.txt -D 1,2 -j _8 --force

I used -j _8 to uses a password with 8 characters only. Is that correct? 

Thanks for the support.
hashcat itself isn't the right place to do that. Filter your wordlist before using it.
