Output is, we should count the items and which items coming more times in the input. I need to print most coming items of 5. Means, output for this input is

I have written a script, but its taking some time to finish this task.

#!/usr/bin/perl
open(INP, '<', $ARGV[0]);
while ($item=<INP>)
{
    chomp($item);
    (exists $query{$item}) ? ($query{$item}=$query{$item}+1) : ($query
+{$item}=1);
}
print join("\n", (sort {$query{$b}<=>$query{$a}} (keys %query))[0..4])
+."\n";
