getting the file name and pass as variable

Can any one suggest me how to check the file extension and pass the name based out of the filename within the folder.

There would be always one latest file in the folder, but extension may vary...
ie .csv, .CSV,.rpt,.xls etc

what is best way to get the latest file name and pass as variable.

I have written with Assumption ie .CSV file and this working fine, which is as below.

Code:
getfilename()
{
cd $DATDIR
v_file=`ls -lrt *.CSV | awk '{print $9}'|grep -v "^d"`
echo $v_file
linecount=`wc -l {$v_file}`
echo 'sanjit count'
echo $linecount
}

NAME
AnyData::Format::CSV - tiedhash & DBI/SQL access to CSV data SYNOPSIS
use AnyData; my $table = adTable( 'CSV', $filename,'r',$flags ); while (my $row = each %$table) { print $row->{name}," " if $row->{country} =~ /us|mx|ca/; } # ... other tied hash operations OR use DBI my $dbh = DBI->connect('dbi:AnyData:'); $dbh->func('table1','CSV', $filename,$flags,'ad_catalog'); my $hits = $dbh->selectall_arrayref( qq{ SELECT name FROM table1 WHERE country = 'us' }); # ... other DBI/SQL operations DESCRIPTION
This is a plug-in format parser for the AnyData and DBD::AnyData modules. It will read column names from the first row of the file, or accept names passed by the user. In addition to column names, the user may set other options as follows: col_names : a comma separated list of column names eol : the end of record mark, by default quote_char : the character used to quote fields " by default escape_char : the character used to escape the quote char, " by default If you are using this with DBD::AnyData, put ad_ in front of the flags, e.g. ad_eol.
