- -0 --no-numerals Don't include numbers.
- -y --symbols Permit special characters ($#%...).
- -r <chars> --remove=<chars> Don't include the given characters.
- -s --secure Generate more random passwords.
- -B --ambiguous Avoid ambiguous characters (e.g. 0, O).
- -h --help Print this help message.
- -C Print the output in columns.
- -1 Print the output one line each.
- -v Don't include vowels.
