Make sure you update hashcat to latest version, as 6.1.1 is out dated.
Run it like this: hashcat -O -m 0 /path/to/hashes/hashes.txt -r /path/to/rule/rockyou-30000.rule /path/to/dictionary/rockyou.txt
Run it like this: hashcat -O -m 0 /path/to/hashes/hashes.txt -r /path/to/rule/rockyou-30000.rule /path/to/dictionary/rockyou.txt
