  • Before you use this command you want to replace everything after the "https:" with the url of the video which you want to download. This string and it's switches will use "youtube-dl" to download the Youtube url into the directory/folder where it is called from. It will output the video using the same name as Youtube uses.

  • A function for streaming youtube to mplayer. The option "-g" for youtube-dl tells it to output the direct video URL, instead of downloading the video. "-fs" tells MPlayer to go FullScreen, and "-quit" makes it less verbose. Requires: youdube-dl ( http://bitbucket.org/rg3/youtube-dl/ ) (Tested in zsh) Show Sample Output

    yt () mplayer -fs -quiet $(youtube-dl -g "$1")
