Answer 1

String#split takes a second argument, the limit.

str.split(' ', 2)

should do the trick.

Answer 2

The second argument of .split() specifies how many splits to do:

'one two three four five'.split(' ', 2)

And the output:

>> ruby -e "print 'one two three four five'.split(' ', 2)"
>> ["one", "two three four five"]

Answer 3

Alternative:

    first= s.match(" ").pre_match
    rest = s.match(" ").post_match

Answer 4

"Ludwig Van Beethoven".split(' ', 2)

The second parameter limits the number you want to split it into.

You can also do:

"Ludwig Van Beethoven".partition(" ")
