The OPTIND you removed is crucial to allow getopts() to work correctly.

But, I'm having trouble matching the arguments you're passing to getopts (edhmou: and name) with your USAGE description of your options:
Code:
Where options are:
	-h	This screen
	-u	Unmount provided nas/share/s
	-d	Delete provided nas/share/s
	-e	Edit provided nas/share/s settings
	-o	Overwrite provided nas/share/s settings
	-m	Displays a TUI/CLI menu to select from

The colon following the u in the option string argument to getopts (edhmou:) says that the -u option takes an option-argument (and the lack of a colon following the other option letters in that string says that no other options take option-arguments), but there is nothing in you code parsing the -u option:
Code:
		u)	doUnmount=true
			mode=umnt
			#shift $(($OPTIND - 1))
			;;

that gathers up the option-argument that getopts will identify for you.

So, do the -d, -e, -o, and -u options (all described as performing an operation on a "provided nas/share/s") get the provided nas/share/s as an option-argument or is the nas/share/s always an operand?
