Add each array element to the lines of a file in ruby

scmuser created the topic: Add each array element to the lines of a file in ruby

Either use Array#each to iterate over your array and call IO#puts to write each element to the file (puts adds a record separator, typically a newline character):

File.open("test.txt", "w+") do |f|
a.each { |element| f.puts(element) }
end

Or pass the whole array to puts:

File.open("test.txt", "w+") do |f|
f.puts(a)
end
