Perl Script - Reading / Writing Binary files

A binary file is a computer file that is not a text file; it may contain any type of data, encoded in binary form for computer storage and processing purposes.

If you want to open a file and read its content in binary mode, you should use the following functions:
* open() to open the file to a file handle.
* binmode() to set the file handle to binary mode.
* read() to read data from the file handle.
* close() to close the file handle.

Below sample Perl script demonstrate the usage of reading / writing the binary files using binary mode.

#!/usr/bin/perl

$buffer = "";
$infile = "binary.dat";
$outfile = "binary_copy.dat";
