I use the following code to searches for the .java scripts and print the date line (1999 - 2002) to see how many scrpts out of date. What I would like is to adapt this to change the copyright.

my $root = 'f:/';
my %hash = ();
#
#  main
#
{
    my @files = getFileList(); # find files within given vobs
    my $n = @files ;
    print STDERR "Searching $n files\n" ;
    my $n = 0 ;
    foreach my $f (@files) # open found files
    {
        $n++ ;
        print STDERR "$n\r" ;
        unless (open( SRC, $f ))
        {
            print STDERR "Unable to open $f: $!\n" ;
            next ;
        }
        while (<SRC>)
        {
            last if (/^\s*package/);
            #next unless (/\$Workfile/m); # get filename
            next unless (/copyright.*application/i); # get copyright
            chomp ;        # remove newline
            s/^\s*\*//;    # remove comments
            s/\s+/ /;      # multiple whitespace into single whitespac
+e
            s/^\s+// ;     # remove any leading whitespace
            s/\s+$// ;     # remove any trailing whitespace
            $hash{ $_ }++;
            last ;
        }
        close (SRC);
    }
    foreach my $k (sort keys %hash)
    {
        my $v = $hash{ $k };
        #print STDERR "$v: $k\n" ;
        print STDERR "$_\n" ;
    }
}
 my @theFiles = ();
 sub
 getFileList()
 {
     my @files = ();
     foreach my $k ("dir1", "dir2")
     {
         @theFiles = ();
         find( \&wanted, "$view/$k/src" );
         push @files, @theFiles ;
     }
     return @files ;
 }
 sub
 wanted
 {
     return unless (-f $_ );
     return unless ($_ =~ /\.java$/);
     push @theFiles, $File::Find::name ;
 }
