can't make cmd

[topspace]

using ubuntu, can't create command for bruting.

Im tried:

./hashcat-cli64.bin -m 400 -a 0 -ot.txt -p : --username hashes.txt


Get nothing:

Usage: hashcat [options] hashfile [mask|wordfiles|directories]

Try --help for more help.

What I missed?

hashes.txt contains hashes by format username:hashalt
