[SunHELP] sort

[Ramon Gonzalez]

Wow. Talk about driving a tank to the grocery store. Sometimes unix tools
work just fine.

sortip.pl:
#!/usr/bin/perl

use strict;

my $file = $ARGV[0] || '-';

open(FILE, $file) or
  die("Usage: sortips.pl file (or standard input)\n");
print join("\n", sort sortips <FILE>), "\n";
close(FILE);

sub sortips {
 chomp($a = $a);
 chomp($b = $b);
 my ($aa, $ab, $ac, $ad) = split /\./, $a;
 my ($ba, $bb, $bc, $bd) = split /\./, $b;
 return ($aa <=> $ba) || ($ab <=> $bb) || ($ac <=> $bc) || ($ad <=> $bd);
}



Then just:
chmod +x sortip.pl

Then:
sortip.pl filename
or
cat ips.txt | sortip.pl
