.shelljoin(array) ⇒ Object Also known as: join

.
All elements are joined into a single string with fields separated by a space, where each element is escaped for the Bourne shell and stringified using to_s
.
ary = ["There's", "a", "time", "and", "place", "for", "everything"]
argv = Shellwords.join(ary)

Array#shelljoin is a shortcut for this function.
ary = ["Don't", "rock", "the", "boat"]

You can also mix non-string objects in the elements as allowed in Array#join.
