Hi, can someone tell me what's the mistake I'm doing in the following code? To be precise, in line- 'printf "%d duplicate records written\n",$name,$para,$out_filename;'?
I get an error:

Argument "sdAb_1193_LgLlama" isn't numeric in printf at ../duplicate.p
+l line 35, <$PROTFILE> chunk 165.
'Redundant argument in printf at ../duplicate.pl line 35, <$PROTFILE> 
+chunk 1164.'

  or die "Cannot open '$prot_filename' because: $!";

my $out_filename = 'duplicates_entries_in_'.$prot_filename;
open my $OUTFILE, '>', $out_filename
  or die "Cannot open '$out_filename' because: $!";

  $para =~ s/^\s*#.*//mg;

  # Trim trailing white space
  $para =~ s/\s+$//;

  printf "%d duplicate records written\n",$name,$para,$out_filename;
  next FASTA_RECORD;
}
}
print "\n";
