Question

Suppose I have an Excel sheet, which has the some numbers say:

• 77787
• 45877
• 78985 so on…

Now I have an directory called as “D://Filehosting” in windows 7 machine. under that directory I have some 500 folders, each of them having 120 files in it. Now I want to delete the contents of each folder which which are 2 months older from the current date. Now the folders are arranged something like below:

• D://Filehosting/Document77787
• D://Filehosting/Document45877 .. so on

Script should take the numbers as mentioned above, and accordingly find the right directory and accordingly delete the contents.Must check if the if the folder exists or not before content deletion approach.

Can it be done using Ruby?

Answer 1

  def del_dir id
    Dir["D:/Filehosting/Document#{id}/*"].each do |fname|
      next unless File.file?(fname)                # skip accident dirs
      if Time.now-File.mtime(fname) > 2*30*24*3600 # nearly 2 months
        puts "[!] will delete #{fname}, mtime=#{File.mtime(fname)}"
        # File.unlink(fname)                       # uncomment this to actually delete
      end
    end
  end
