[Bash] Listado IP’s

Este código no es de mucha utilidad per se, solo es una prueba de concepto de como podríamos sacar todas las IP’s de un rango dado:

view source
print?
01#!/bin/bash
02#comprobamos que han introducido al menos un parametro
03if [ -z $1 ]
04    then
05           
06    echo "No ha especificado ningun parametro. Por favor incluya la IP origen del rango y la IP final del rango"
07     
08else
09    if [ -z $2 ]
10    then
11        echo "Debe introducir como segundo parámetro la IP final del rango"
12    else
13         
14        let BIT1=`echo $1 | cut -d "." -f 1`
15        let BIT2=`echo $1 | cut -d "." -f 2`
