Hi haukex
I got your point. Actually I thought I was missing something in this compare function, while calculating md5 checksum. That is why I posted that function alone. Here is the full code.
use strict;
use warnings;
use Digest::MD5;
sub compare {
my $pre_version =shift;
my $new_version =shift;
print("previous version: $pre_version\n");
print("new version : $new_version\n");
my $pre = Digest::MD5->new;
open (PRE, "$pre_version");
$pre->addfile(*PRE);
close(PRE);
my $pre_digest = $pre->hexdigest;
#print "pre digest=$pre_digest\n";
my $new = Digest::MD5->new;
open (NEW, "$new_version");
$new->addfile(*NEW);
close(NEW);
my $new_digest = $new->hexdigest;
#print "new digest=$new_digest\n";
if ($pre_digest eq $new_digest) {
print("Equal\n");
return 0;
} else {
print("Not Equal\n");
return 1;
}
}
compare($oldfile_path, $newfile_path);
Update:variable name updated from $co to $new
All is well. I learn by answering your questions...

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

are good places to start.
