The double square operator is bash specific. The portable way who to
check for a start of a string is to use case as:

	case "$verify_cmd" in
	id*) echo starts with id;;
	mount*) echo starts with mount;;
	esac

And it may be a bit cleaner to put the checks into a separate functions
the indentation is getting out of the hand here.
