If I correctly understand your goal, perhaps File::Find and File::Slurp will be helpful:

use Modern::Perl;
use File::Find;
use File::Slurp qw/read_file/;

my $startDir = '.';

find( { wanted => \&countLines, }, $startDir );

sub countLines {
    /\.txt$/ or return;

    my $completePath = $File::Find::name;
    my $curDir       = $File::Find::dir;
    my $curFile      = $_;

    my @fileLines = read_file $curFile;
    my $numLines  = @fileLines;
    say "Cur dir: $curDir; Cur file: $curFile; Num Lines: $numLines";
}

Partial output:

Cur dir: ./test/test bbb; Cur file: B.txt; Num Lines: 6

The script above will start at $startDir and descent into directories, processing only *.txt files. Consider using a hash (key = $curDir; val = totLines) to store totalFileLines per directory.

Hope this helps!
