in thread grab newest file

If you really want to use the least resources: Updated for newest file: 
my $report = do {
    opendir my $dh, $path or die "open '$path' $!";
    my ( $name, $mtime ) = ( '', ~0 );
    while ( my $file = readdir $dh ) {
        stat "$path/$file";
        ( $name, $mtime ) = ( $file, -M _ ) if $file =~ /B1006/ and $m
+time > -M _;
        }
    $name;
    };

    Comparing mtime (timestamp) and -M is bogus. -M gives you the script start time minus file modification time, in days.

    update - oops, sometimes I'm a lousy reader - the referred post compares only -M against -M. Read the above just as a general statement ;-)

    thanks jwkrahn

      The code I posted is only comparing the -M value with other -M values. The $mtime in the code is just a variable name.
