Within our code we are trying to accomplish $-$

Or with the recursion option $($in a slightly different folder, just for the sake of demonstration$)$:

L $/$home$/$algol$/$ics$32/-$r $-$s Schedule.txt

And the resulting output:

$/$home$/$algol$/$ics$32/$Schedule$.$txt

$/$home$/$algol$/$ics$32/$assignments$/$Schedule$.$txt

$/$home$/$algol$/$ics$32/$laboratories$/$Schedule$.$txt

$/$home$/$algol$/$ics$32/$lectures$/$Schedule$.$txt

$/$home$/$algol$/$ics$32/$workoutprojects$/$Schedule$.$txt

We are trying to make the program be able to use two commands, both $-$r and $-$s together or even $-$r and $-$f together basically where our commands have a recursive option rather than standalone commands of $-$f or $-$s or even $-$e
