File downloader objects are the ones responsible of downloading the
actual video file and writing it to disk if the user has requested
it, among some other tasks. In most cases there should be one per
program. As, given a video URL, the downloader doesn’t know how to
extract all the needed information, task that InfoExtractors do, it
has to pass the URL to one of them.

For this, file downloader objects have a method that allows
InfoExtractors to be registered in a given order. When it is passed
a URL, the file downloader handles it to the first InfoExtractor it
finds that reports being able to handle it. The InfoExtractor extracts
all the information about the video or videos the URL refers to, and
asks the FileDownloader to process the video information, possibly
downloading the video.

File downloaders accept a lot of parameters. In order not to saturate
the object constructor with arguments, it receives a dictionary of
options instead. These options are available through the params
attribute for the InfoExtractors to use. The FileDownloader also
registers itself as the downloader in charge for the InfoExtractors
that are added to it, so this is a "mutual registration".

Available options:

username: Username for authentication purposes.
password: Password for authentication purposes.
usenetrc: Use netrc for authentication instead.
quiet: Do not print messages to stdout.
forceurl: Force printing final URL.
forcetitle: Force printing title.
forcethumbnail: Force printing thumbnail URL.
forcedescription: Force printing description.
simulate: Do not download the video files.
format: Video format code.
format_limit: Highest quality format to try.
outtmpl: Template for output names.
ignoreerrors: Do not stop on download errors.
ratelimit: Download speed limit, in bytes/sec.
nooverwrites: Prevent overwriting files.
retries: Number of times to retry for HTTP error 5xx
continuedl: Try to continue downloads if possible.
noprogress: Do not print the progress bar.
playliststart: Playlist item to start at.
playlistend: Playlist item to end at.
logtostderr: Log messages to stderr instead of stdout.

I save this script like download.sh
If there is an error occured by this this script, you can leave message to me..
Or directly go to this site

made it executable by “chmod” and ran it like:
alfian@XsilenT:~$ sudo ./download.sh http://www.youtube.com/watch?v=AWggPLXeOkU

Good luck..
