Subject: Re: Files management with Ruby

Dir.entries('A').each do |file|

Returns a string with the name of file without the "A" segment of the path.
It's something like [".", "..", "Today"]

So, when opening, a quick fix would do

File.open(File.join("A", file), 'w') {|file|

Just to 'prepend' the "A" to render "A/Today"

The matching is broken also.
You're seaching for "today" expecting a match with "Today" and your
regexp is case sensitive.

Make it insensitive with

next if !(file.match(/today/i))

Another fail is the mode you're opening your file.
You're trying to append but you're opening in 'w' mode.
Fix it with...

File.open(file, 'a') {|file|

File.open with a block takes care of closing your file, so you
shouldn't bother with this.
Just strip off this line
# file.close

I think you want to append lines, am I right?
Or you'll get a file like this
hellohellohellohellohellohellohello

So, you should insert the line breaks.
File#write doesn't do this for you.
Try using puts! Yes! The same you're used to.
Just send puts to the file object.

file.puts("hello")

The complete code

def append_data_to_daily_files
  Dir.entries('A').each do |file|
    next if !(file.match(/today/i))
    File.open(File.join("A",file), 'a') do |file|
      file.puts("hello")
    end
  end
end
