Lets cut the long discussion <a class="zem_slink freebase/en/short_subject" title="Short film" rel="wikipedia" href="http://en.wikipedia.org/wiki/Short_film">short and directly give you the script. The script is combination of all the posts that I did in the past about youtube <a class="zem_slink freebase/en/uploading_and_downloading" title="Uploading and downloading" rel="wikipedia" href="http://en.wikipedia.org/wiki/Uploading_and_downloading">downloads. You need to copy all the <a class="zem_slink freebase/en/uniform_resource_locator" title="Uniform Resource Locator" rel="wikipedia" href="http://en.wikipedia.org/wiki/Uniform_Resource_Locator">URL&#8217;s in a file called &#8221;~/youtube.urls&#8221; which you want to be downloaded. Or if you need to donwload the related videos, then save the html of the page and give it as the first argument for the script. So, here&#8217;s the scrit:

#!/bin/bash –
