Error PERL - Selecting specific files based on 'date stamp' values

Hi,

I've list of files in a directory, which have date stamp value in their names.

Code:
ex: 
abc_data_20071102.csv, 
abc_data_20091221.csv, 
abc_data_20100110.csv, 
abc_data_20100222.csv, 
abc_data_20080620.csv,... etc.,

I need to select and process only files, within the given date range.

Code:
ex: files starting from the date 20090101 to 20101231

I've written below scrtipt to select files starting from 'abc_data_' and ending with '.csv'.
This script is selecting all files starting abc_data_ and ending with '.csv'.

Code:
my @files = </test/ganap/abc_*.csv>;
foreach my $inputfilename (@files) {
   open( my $in_fh, "<", $inputfilename ) or die "Can't open $inputfilename : $!";
#.......................... file processing
}
close($in_fh);

Could any of you help me to achieve my selection criteria?Smilie

NAME
Text::CSV::Encoded::Coder::EncodeGuess - Text::CSV::Encoded coder class using Encode::Guess SYNOPSIS
use Text::CSV::Encoded coder_class => 'Text::CSV::Encoded::Coder::EncodeGuess'; use Spreadsheet::ParseExcel; my $csv = Text::CSV::Encoded->new(); $csv->encoding( ['ucs2', 'ascii'] ); # guessing ucs2 or ascii? $csv->encoding_to_combine('shiftjis'); my $excel = Spreadsheet::ParseExcel::Workbook->Parse( $file ); my $sheet = $excel->{Worksheet}->[0]; for my $row ( $sheet->{MinRow} .. $sheet->{MaxRow} ) { my @fields; for my $col ( $sheet->{MinCol} .. $sheet->{MaxCol} ) { my $cell = $sheet->{Cells}[$row][$col]; push @fields, $cell->{Val}; } $csv->combine( @fields ) or die; print $csv->string, " "; } DESCRIPTION
This module is inherited from Text::CSV::Encoded::Coder::Encode. USE
Except for 2 attributes, same as Text::CSV::Encoded::Coder::Encode. encoding_in $csv = $csv->encoding_in( $encoding_list_ref ); The accessor to an encoding for pre-parsing CSV strings. If no encoding is given, returns current $encoding, otherwise the object itself. $encoding_list_ref = $csv->encoding_in() When you pass a list reference, it might guess the encoding from the given list. $csv->encoding_in( ['shiftjis', 'euc-jp', 'iso-20022-jp'] ); If it cannot guess the encoding, the first encoding of the list is used. encoding $csv = $csv->encoding( $encoding_list_ref ); $encoding_list_ref = $csv->encoding(); You can pass a list reference to this attribute only: * For list data consumed by combine(). * For list reference returned by getline(). In other word, in "combine" and "print", it might guess an encoding for the passing list data. If it cannot guess the encoding, the first encoding of the list is used. SEE ALSO
