It isn't quite the same in this case because the input is not in sorted order and (since the month and day fields in the date are variable length [1 or 2 digits instead of always two digits with a leading 0 when needed] in the general case, the year is after the month and day, and there are different field separators needed to sort the parts of the date and the other field) the sort utility can't be used without a separate processing step to normalize the date.

If the OP doesn't care about the output order, this is trivial to do with awk. If the output needs to be sorted by year, month, day, and input column 6; the processing is more involved. I'm still waiting for radius to say whether or not output order matters.

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" AUTHOR
