Put quotes around args var and add e and u flags, which
do the following:
e - terminates the script if an error occurs. This is
certainly desirable behavior. We don't want the script to chug
along with unpredictable behavior if an error occurred.
u - terminates the script if an undefined variable is encountered.
It is also desirable to terminate here because it might lead to
unexpected behavior.
