hmmmmm. this is certainly a stubborn little script we're dealing with. alright.

About Warnings
use warnings; is equivalent to putting the little -w at the end of your 'shebang line'. So if your Perl implementation does not grok use warnings' change your script to read #!/usr/bin/perl -w at the top of your code. This will have the same effect. Warnings have the effect of telling Perl you want it to complain about any code that's incorrect or not clear. An example would be (at least until Perl 6 comes out):

Without warnings, Perl will compile and run the following code

    # this is a slice, probably not intended
    @someList[0] = 'foo';
[download]

but with warnings, if you tried to use the above code, Perl will complain:

@someList[0] better written as $someList[0]
[download]

which is what you want. Using warnings (either through 'use warnings' or the '-w' flag is one of the most important steps you can take towards being a good Perl programmer.

Back To the Problem At Hand
That all being said, 'use warnings;' is not needed to make this script run correctly.

Some Questions

• What version of Perl are you using, and on which platform?
• How big are the directories that you're trying to parse?
• Are the directories local or are they network shares?
And have you tried adding some debugging to the script to see what it's doing? Maybe you want to do something like:

#!/usr/bin/perl -w #alternative warning syntax
use strict;

use File::Find;

#########################################################
# a debugging variable
#########################################################
my $totalChanges;

my @dirs = qw(.);

find ( { wanted => \&change, no_chdir => 1}, @dirs );

sub change
{
    my $file = $File::Find::name;
    
    if ( -f $file && $file =~ /\.html$/ )
    {
        ###################################
        # debugging print statement
        ###################################

        print "going into $file\n";
        my $buffer;
        open(IN, $file) or warn "CAN'T OPEN $file!\n";

        {
            local $/ = undef;
            $buffer = (<IN>);
        }
        
        close IN;
        
        my $changecount = ($buffer =~ s/FOO/BAR/gi);
        
        if ($changecount)
        {
           #######################################
           # increment debug variable
           #######################################
           $totalChanges++;
          
           #######################################
           # debugging statement
           #######################################
           print "changed $changecount instances in $file\n";
            open(OPF,">$file") or warn "NOT OPENING $file FOR MOD, $!\
+n";
            print OPF "$buffer";
            close OPF;
        }
    }
}

###################################################
# debugging statement
###################################################
print "$totalChanges files changed\n";

I will have to play around with what you gave me to make it work. I appreciate all of your help on this! Can you just explain what this line is doing?

find ( { wanted => \&change, no_chdir => 1}, @dirs );
[download]

Is 'wanted' a function in the find module?? What is 'no_chdir => 1' doing??? Answers to your questions about what I am using. Perl version 5.005 on Windows NT. Directories are small size and are local
