SC2034 (warning): EX_OK appears unused. SC2035 (info): Use ./*glob* or -- *glob* so names with dashes won't become options. SC2068 (error): Double quote array expansions to avoid re-splitting elements. SC2086 (info): Double quote to prevent globbing and word splitting. SC2112 (warning): 'function' keyword is non-standard. Delete it. SC2124 (warning): Assigning an array to a string! Assign as array, or use * instead of @ to concatenate. SC3001 (warning): In POSIX sh, process substitution is undefined. SC3006 (warning): In POSIX sh, standalone ((..)) is undefined. Also, remove unnecessary braces, and update copyright.
