You're quoting help to 'getopts' shell built-in command --
you are mistaking it for 'getopt' program from util-linux.

$ man getopt_long
getopt(3)            Library Functions Manual              getopt(3)

NAME
       getopt,  getopt_long,  getopt_long_only,  optarg, optind, opterr, optopt -
       Parse command-line options

The getopt family is a pain in the ass. I wrote my own command-line parsing,
though I do not use it in legacy apps.

Overcoming
 
Water overcomes the stone;
Without substance it requires no opening;
This is the benefit of taking no action.
Yet benefit without action,
And experience without abstraction,
Are practiced by very few.
