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);

    Any idea why this happens?

    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/ /; }

    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...

    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
