copy a csv file in ruby

To copy a CSV file in Ruby, you can use the FileUtils module's cp method which is provided by the Ruby Standard Library.

main.rb
require 'fileutils'

FileUtils.cp('source_file.csv', 'destination_file.csv')
77 chars
4 lines

In the above code snippet, we require the fileutils library and call its cp method, passing the source file path as the first argument and the destination file path as the second argument. This copies the contents of the source file to the destination file.

Note: If the destination file already exists, it will be overwritten by this method. If you want to avoid overwriting it, you can use cp_r method instead of cp.
