How to download youtube videos on ubuntu 12.10 and lower versions machine

1. You can use terminal-based command :

$ sudo apt-get install youtube-dl
$ sudo youtube-dl --update
$ sudo apt-get install python
$ which youtube-dl
$ youtube-dl --version

Then, to download the youtube-video, simply type :
$ youtube-dl http://www.youtube.com/watch?v=wcVvE-BNWPs

Alternative way (also terminal-based command) :

$ sudo apt-get remove youtube-dl
$ sudo rm /usr/local/bin/youtube-dl
$ sudo wget --no-check-certificate https://github.com/rg3/youtube-dl/raw/2011.02.25c/youtube-dl -O /usr/local/bin/youtube-dl
$ sudo chmod +x /usr/local/bin/youtube-dl
$sudo youtube-dl --update

on some ubuntu machines you might want to change the path to
/usr/bin other than /usr/local/bin as stated in the above commands where they apply.

Usage can be as follows:

youtube-dl -o '%(stitle)s.%(ext)s' 'file_2_download'

e.g youtube -dl -o xxx.mp4 http://www.wtf.xxx/vSadG56Jij

where of course file_2_download is the url of your desired file. An easy way to update your installation is to periodically run:
$ sudo youtube-dl --update
$ which youtube-dl
$ youtube-dl --version
