How to count the number of lines in multiple text files?

Question

Programming

Maybe someone knows, maybe there is some kind of tool that counts the number of lines in several text files? I would like to estimate the size of the C ++ project in lines, it is desirable that empty lines would not be taken into account.

Answer 1

If you want completely with blackjack and the croupier, then there is CCCC - C and C ++ Code Counter

Answer 2

Hmm, the size in lines, I also controlled this before, but when my big project exceeded 10 thousand lines, I somehow stopped monitoring this, something b / kb / mb says more.

Answer 3

counting lines in files in the current directory (including subdirectories) in perl:

sub countdir {
  my $dir = shift @_;
  my @files = < $dir >;
  my $count = 0;
  for my $file (@files) {
    if (-d $file) {
      $count += countdir("$file/*");
      next;
    }		
    open my $fd, '<', $file or die "cannot open file $file\n";
    my @lines = <$fd>;
    close $fd;
    map { $count++ if ($_ !~ /^\s*$/) } @lines;
  }
  return $count;
}

print countdir('./*') . "\n";
