Your code works fine for me, with the slight change of chomping $array at the beginning of the outer loop.

But I'm not sure why you don't just put all the filenames in @ARGV: 

#!/usr/bin/perl

use strict;
use warnings;

#edit contains the complete path of the files to be edited
my $path = "./edit" ;

#geting a file handler
open(FL, "$path");

#getting all the file names in the @ARGV so that i can process them
chomp(@ARGV = <FL>);
# $INPUT_RECORD_SEPARATOR
$/="";
# $INPLACE_EDIT
$^I=".bak";
while(<>)
{
    s/CONFIDENTIAL(.*?)own\s+risk/ /sm;
    print ;
}

It's possible you are having file permission problems, in which case, you are probably better off not relying on $^I but instead explicitly renaming each file and opening the old and new names, checking each operation for success and giving a meaningful error message on failure.
