How to create a file in Ruby


Use:

File.open("out.txt", [your-option-string]) {|f| f.write("write your stuff here") }

where your options are:

  • r - Read only. The file must exist.
  • w - Create an empty file for writing.
  • a - Append to a file.The file is created if it does not exist.
  • r+ - Open a file for update both reading and writing. The file must exist.
  • w+ - Create an empty file for both reading and writing.
  • a+ - Open a file for reading and appending. The file is created if it does not exist.

In your case, 'w' is preferable.

OR you could have:

out_file = File.new("out.txt", "w")#...out_file.puts("write your stuff here")#...out_file.close


Try

File.open("out.txt", "w") do |f|       f.write(data_you_want_to_write)   end

without using the

File.new "out.txt"


Try using "w+" as the write mode instead of just "w":

File.open("out.txt", "w+") { |file| file.write("boo!") }
