Top Forums Shell Programming and Scripting awk second largest, third largest value Post 302555327 by sk1418 on Wednesday 14th of September 2011 12:09:27 PM

here I made an example, hope that it helps:

Code:
a sorted file (descending) named t

kent$  cat t
foo 100
foo 99
foo 98
foo 97
foo 96
foo 95
foo 94
foo 93
foo 92
....
foo 5
foo 4
foo 3
foo 2
foo 1

awk one liner gives you 8 largest number with 5 as difference with previous :


kent$  awk 'NR==1{max=$2;next;}max-$2>5{print $0;max=$2;c++;}c==8{exit}' t
foo 94
foo 88
foo 82
foo 76
foo 70
foo 64
foo 58
foo 52

Mojo::Parameters(3pm)					User Contributed Perl Documentation				     Mojo::Parameters(3pm)

NAME
Mojo::Parameters - Parameter container SYNOPSIS
use Mojo::Parameters; my $p = Mojo::Parameters->new(foo => 'bar', baz => 23); DESCRIPTION
Mojo::Parameters is a container for form parameters. ATTRIBUTES
Mojo::Parameters implements the following attributes. "charset" my $charset = $p->charset; $p = $p->charset('UTF-8'); Charset used for decoding parameters, defaults to "UTF-8". "pair_separator" my $separator = $p->pair_separator; $p = $p->pair_separator(';'); Separator for parameter pairs, defaults to "&". METHODS
Mojo::Parameters inherits all methods from Mojo::Base and implements the following new ones. "new" my $p = Mojo::Parameters->new; my $p = Mojo::Parameters->new('foo=b%3Bar&baz=23'); my $p = Mojo::Parameters->new(foo => 'b;ar'); my $p = Mojo::Parameters->new(foo => ['ba;r', 'b;az']); my $p = Mojo::Parameters->new(foo => ['ba;r', 'b;az'], bar => 23); Construct a new Mojo::Parameters object. "append" $p = $p->append(foo => 'ba;r'); $p = $p->append(foo => ['ba;r', 'b;az']); $p = $p->append(foo => ['ba;r', 'b;az'], bar => 23); Append parameters. # "foo=bar&foo=baz" Mojo::Parameters->new('foo=bar')->append(foo => 'baz'); # "foo=bar&foo=baz&foo=yada" Mojo::Parameters->new('foo=bar')->append(foo => ['baz', 'yada']); # "foo=bar&foo=baz&foo=yada&bar=23" Mojo::Parameters->new('foo=bar')->append(foo => ['baz', 'yada'], bar => 23); "clone" my $p2 = $p->clone; Clone parameters. "merge" $p = $p->merge(Mojo::Parameters->new(foo => 'b;ar', baz => 23)); Merge parameters. "param" my @names = $p->param; my $foo = $p->param('foo'); my @foo = $p->param('foo'); my $foo = $p->param(foo => 'ba;r'); my @foo = $p->param(foo => qw(ba;r ba;z)); Check and replace parameter values. "params" my $params = $p->params; $p = $p->params([foo => 'b;ar', baz => 23]); Parsed parameters. "parse" $p = $p->parse('foo=b%3Bar&baz=23'); Parse parameters. "remove" $p = $p->remove('foo'); Remove parameters. # "bar=yada" Mojo::Parameters->new('foo=bar&foo=baz&bar=yada')->remove('foo'); "to_hash" my $hash = $p->to_hash; Turn parameters into a hash reference. # "baz" Mojo::Parameters->new('foo=bar&foo=baz')->to_hash->{foo}[1]; "to_string" my $string = $p->to_string; Turn parameters into a string.
