sort!()

Sorts self. Comparisons for the sort will be done using the <=> operator or using an optional code block. The block implements a comparison between a and b, returning -1, 0, or +1. See also Enumerable#sort_by.
a = [ "d", "a", "e", "c", "b" ] a.sort! #=> ["a", "b", "c", "d", "e"] a.sort! {|x,y| y <=> x } #=> ["e", "d", "c", "b", "a"]
