I can't create a file in Ruby

Question

I'm pretty new to Ruby. I want to create a file by writing:

file.new "test.txt", "w"

And de result is:

NameError: undefined local variable or method 'file' for main:Object
from (irb):4
from c:/Ruby21/bin/irb:11:in '<main>'

I don't know what it means. And another question if I may: How do I say in what folder I want to save the file?

`File` not `file`, http://stackoverflow.com/questions/7911669/create-file-in-ruby — bruchowski, Oct 26 '14 at 01:50

You are writing file with a lower case f, which means you are accessing a local variable or a method. In order to access the File class, you must write it with a upper case F:

File.new 'test.txt', 'w' do |file|
  file.write 'Some text.'
end

It should be File, not file.

File.new "test.txt", "w"

file isn't defined, you have to use File:

File.new "test.txt", "w"
