I'm assuming you have something like this:

Code:

2009  # year dir
    # month dir
  -  1
  -  2
        # days
      - 01  # already partly correct
      - 02
      - 3
      - 2009_02_04  #fully correct
      ...
  -  3
  - 2009_04
   -05

If you can assume that anything with a "_" is already fully correct, you don't have to test for length.

I'd do this in Perl. Something like

Code:

#!/usr/bin/perl
foreach(<200*>) {
  $year=$_;
  opendir(YEAR,$year);
  while(defined($month=readdir(YEAR))) {
     next if $month =~ /^\./;
     next if $month =~ /_/;
     opendir(MONTH, "$year/$month") ;
     while(defined($day=readdir(MONTH))) {
        next if $day =~ /^\./;
        next if $day =~ /_/;
        $newname=sprintf("%d_%0.2d_%0.2d",$year,$month,$day);
        print " --  $year $month $day is $year/$month/$newname\n"; 
        # rename "$year/$month/$day", "$year/$month/$newname";
     }
     
     $newname=sprintf("%d_%0.2d",$year,$month);
     print "$year $month is $year/$newname\n"; 
     # rename "$year/$month", "$year/$newname";
    
  }
}

I wrote this to be obvious rather than clever. If I've misunderstood your directory structure, of course this won't be right, but you can modify it.

When you are satisfied this will do what you want, uncomment the rename lines.

HTML::FormHandler::Field::Date(3pm)			User Contributed Perl Documentation		       HTML::FormHandler::Field::Date(3pm)

NAME

       HTML::FormHandler::Field::Date - a date field with formats

VERSION

       version 0.40013

SUMMARY

       This field may be used with the jQuery Datepicker plugin.

       You can specify the format for the date using jQuery formatDate strings or DateTime strftime formats. (Default format is format =>
       '%Y-%m-%d'.)

	  d  - "%e" - day of month (no leading zero)
	  dd - "%d" - day of month (two digit)
	  o  - "%{day_of_year}" - day of the year (no leading zeros)
	  oo - "%j" - day of the year (three digit)
	  D  - "%a" - day name short
	  DD - "%A" - day name long
	  m  - "%{day_of_month" - month of year (no leading zero)
	  mm - "%m" - month of year (two digit) "%m"
	  M  - "%b" - month name short
	  MM - "%B" - month name long
	  y  - "%y" - year (two digit)
	  yy - "%Y" - year (four digit)
	  @  - "%s" - Unix timestamp (ms since 01/01/1970)

       For example:

	  has_field 'start_date' => ( type => 'Date', format => "dd/mm/y" );

       or

	  has_field 'start_date' => ( type => 'Date', format => "%d/%m/%y" );

       You can also set 'date_end' and 'date_start' attributes for validation of the date range. Use iso_8601 formats for these dates ("yyyy-mm-
       dd");

	  has_field 'start_date' => ( type => 'Date', date_start => "2009-12-25" );

       Customize error messages 'date_early' and 'date_late':

	  has_field 'start_date' => ( type => 'Date,
	      messages => { date_early => 'Pick a later date',
			    date_late  => 'Pick an earlier date', } );

       If form has 'is_html5' flag active it will render <input type="date" ... /> instead of type="text"
