How to rename a file in Ruby?

Question

Here\'s my .rb file:

puts \"Renaming files...\"

folder_path = \"/home/papuccino1/Desktop/Test\"
Dir.glob(folder_path + \"/*\").sort.each do |f|
    filename         


        

Answer 1

Don't use this pattern unless you are ready to put proper quoting around filenames:

`mv test.txt hope.txt`

Indeed, suppose instead of "hope.txt" you have a file called "foo the bar.txt", the result will not be what you expect.
