I need help to know how to create a script that takes string options and not only 1 charecter.

I wanted to make a script that takes 'string' options eg. hscript.sh -product XXX -version XXX
I know that I can make a script that takes "1 Charecter " options eg. hscript.sh -m XXX -l XXX -s XXX , with a function called "getopts".

When i tried to use "getopts" to make the options as a string and not only 1charecter the script didn't work.
