this is one of the way. try this
#!/usr/bin/env perl
use strict;
my $hits=0;
my $string_to_find="string";
my $file = "filename";
open (LOGFILE, $file);
my @cont = <LOGFILE>;
close(LOGFILE);
for(my $i = 0; $i <= $#cont; $i++) {
my $line = $cont[$i];
if ($line =~ /$string_to_find/i) {
my $st;
($i <= 5) ? ($st = 0) : ($st = $i - 5);
my $ln = $i - 1;
my $eln = $i + 1;
my $en = $i + 5;
($en > $#cont) ? ($en = $#cont) : ();
print @cont[$st..$ln];
print $line;
print @cont[$eln..$en];
}
}

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).

or How to display code and escape characters
are good places to start.
