Revered monks,
I am trying to compare 2 simple arrays @file and @file2.
After the comparision I need:
- matched elments
- elements in @file1 not in @file2 and
- elements in @file2 not in @file1
I am using the following code... Is this the best way of doin it??? is there a optimization or even a direct function for this?
%seen = ();
@seen{ @file1 } = ();
@infile1only = grep { ! exists $seen{$_} } @file2;
%seen =();
@seen{ @file2 } = ();
@infile2only = grep { ! exists $seen{$_} } @file1;
@matched = grep { exists $seen{$_} } @file1;
thanks,
narashima

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
