Re^2: Open a directory and recursively process files

[Dr Manhattan]

Hi blue cowdawg

I tried your sub, but it still does not work. ".:Permission denied at project6.pl line 16." Which is    open FIN,"< $fname" or die "$fname:$!"; Any idea why this happens?

#!/usr/bin/perl -w 
use strict;
my $dir = 'C:\Users\Zandre Botha\Desktop\Text Files';

opendir (DIR, $dir) or die "cannot opendir $dir"; 

foreach my $file (readdir(DIR)) 
{ 
    &process_file ($file); 
}

sub process_file
{
    my $fname=join("/",@_);
   
   open FIN,"< $fname" or die "$fname:$!";
   my @lines=<FIN>;
   chomp @lines;
   close FIN;
   my $count=0;
   foreach my $line(@lines)
   {
       map { $count++ } split (/[\s\t\n]+/,$line);
   } 
   
   printf "There are %d words in %s\n",$count,$fname;
}

closedir (DIR);

If you read the diagnostic carefully you'll notice it complains about the filename "." which is actually your current working directory. You forgot the line

next if ($file eq '.') || ( $file eq '..');

just prior to the call to the sub. I think I mentioned that a few answers ago...

Because you don't have permission -- ask the computer why

stat, file, ls

or die Fudge( "q{$file}:" );
sub Fudge {
    use Errno();
    join qq/\n/,
      "Error @_",
      map { "  $_" } int( $! ) . q/ / . $!,
      int( $^E ) . q/ / . $^E,
      grep( { $!{$_} } keys %! ),
      q/ /;
}

You failed to include a couple of lines of code you were given the last time you asked this question. Guess which ones:Re^2: Open a folder
