Got the desired output:
# use strict;
#use warnings;
my %hash;
open my $fh, '<','abc.txt' or die $!;
while (<$fh>) {
chomp;
my ($key, $val , $val1) = split '\|';
$hash{$val1}++;
}
@sorted= reverse sort keys %hash;
#print "After reverse sorting @sorted\n";
################sorts and prints the array salaries in descending orde
+r
for($i=0;$i<=20;$i++)
{
for($j=$i+1;$j<=20;$j++)
{
if ($sorted[$i] < $sorted[$j])
{
$temp = $sorted[$i];
$sorted[$i] = $sorted[$j];
$sorted[$j] = $temp;
}
}
}
print "The salaries in unique and sorted descending order are\n";
print "@sorted\n";
Thanks All.

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.
