<p>In questi giorni mi e` capitato di dover scaricare varie collezioni da <a href="https://en.wikipedia.org/wiki/Internet_Archive">archive.org</a>, una libreria digitale multimediale la cui missione e` laccesso universale a tutta la conoscenza.</p>
<p>Principalmente lo uso per scaricare tantissime registrazioni live di vari concerti registrati a mio avviso in maniera impeccabile.</p>
<p>Nel sito si trova una guida per scaricare in bulk usando wget e gli strumenti del sito, ma risulta piuttosto prolissa e complicata se si vuole fare un download al volo.</p>
<p>Questo e` lo script che uso, modificato da <a href="https://github.com/ghalfacree/bash-scripts/blob/master/archivedownload.sh">questo</a> script: e` scritto in bash e funziona su tutte le distribuzioni sulle quali e` installato wget, tail e sed.</p>
<pre class="wp-code-highlight prettyprint linenums:1">#!/bin/bash
