Question

I need to replace ” for ‘ in all csv files in one directory. I wonder if there is either

• nice one line piece of code to do that or
• if I use the fastest way to solve what I do

My code is

files = Dir["*.csv"]

files.each do |file_name|
  File.open(file_name, "w") {|file| 
    file.puts File.read(file_name).gsub('"', "'")
  }
end

update

• ruby 1.9.3p194 (2012-04-20) [i386-mingw32]
• I prefer ruby only solution

You can edit the files in place like so:

ruby -pi~ -e "gsub(/\"/, \"'\")" *.csv
