Using Seq As A Variable With Padded Digits
Hi all. Im trying to use a sequence in a while loop like this below. I need it for navigating a year, month, day folder structure where a user can input the start date and have it go to the desired end date. The script will grab a certain file on each day then move onto the next. Ive got all that worked out using a static set of years in a for loop rather then a while loop with a seq. The problem is when I run into the month andn day folders as they are 01 02 03..10 11. Using the + 1 method it wont cd to the folders below 10 because the var is 1 2 3 instead of 01 02 03. Is there a way to make it add the zero to values below 10 but still keep count?



Code:
startdate=1
enddate=12
a=$startdate
if [ $a -lt 10 ]
   then a=0$a
   fi
 
while [ $a -lt $enddate ]
   DO OTHER THINGS HERE
   startdate=`expr $startdate + 1`
   a=$startdate
if [ $a -lt 10 ]
   then a=0$a
   fi
   done

html::formhandler::field::date

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"
