I'm trying to put together code that will find all the files within a directory, search for a particular string within each file and replace it accordingly. Eventually, I'd like to make the code look recursively through directories. Below is the code I've put together; there are two problems with it:

  1. It doesn't get all the files in the directory
  2. It doesn't search through each file making the desired replacement

I'd appreciate help in understanding where I went wrong. 

use warnings;
use strict;

my $curUrl = "http://localhost:8080";
my $tarUrl = "http://localhost";

opendir DIR, $ARGV[0] or die "Could not open directory";
my @files = grep { -f $_ } readdir DIR;

foreach (@files) {
    open FILE, "+>", "$ARGV[0]\\$_" or die "Could not open file -- $_"
+;
    while (my $line = <FILE>) {
        $line =~ s/$curUrl/$tarUrl/g;
    }
    close FILE;
}

closedir DIR;
