Hi, I've been googling through the internet trying to find articles and sample on the optional flag in commandline argument. I was hoping someone could point me to the right direction for the example. I found one but it has very little information.

-d, --nodisplays

Suppress all displays.
I've been trying to write a program to show different types of output whether the flag is there or not but it doesn't work.
