--longoptions does not exist. The getopts built-in command does not take such options. You may have used some external getopts command (which you might find with which getopts) but your example does not apply to normal systems
And my pet peeve, you're not quoting any of your variables, opening up to bugs galore.
Don't post code you haven't checkd, for pity's sake.
The bash scripting ecosystem is rife enough with bad examples and bad code, we really don't need any more atrocious and unchecked posts about it.
There is so much wrong here, you obviously have not checked your code at all.
