These bash parameters are used to process command line arguments in a bash shell script, to get process status, exit status and options flag.

When you need to send simple values in a script then it is better to use argument variables.

But if you want to send data in a formatted way then it is better to use getopts function to retrieve argument values.

The double dash (–) is used to end the options list.

After the shell sees the double dash, the remaining inputs are treated as parameters and not as options.#!
