Hi varalaxmibbnl,
Several good advice has been given, however comparing the content of the files you presented in your original post. I can see that file1 is contained in file2 in such a way that if the two files are saved in different arrays, one can use splice to get the difference of the files like:
use warnings;
use strict;
use Inline::Files;
my @file1 = <DATA1>; # updated
my @file2 = <DATA2>; # updated
print $_ for splice @file2, $#file1 - 1, $#file2;
__DATA1__
hi
1
hw
r
u
hi
2
hw
r
u
__DATA2__
hi
1
hw
r
u
hi
2
hw
r
u
hi
3
hw
r
u
NOTE:
This might not work like you wanted, if the lines of the first file doesn't follow just like that of the second file.
Updated:
Change chomp(my @file1 = <DATA1>);
chomp is really not needed here, as pointed out by hdb
If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.

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).
