Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

I've made a script that's a little prettier:

#!/bin/sh for a in $@ do for video in $(curl -s $a | grep -o "url='http://www.youtube.com/watch?v=[^']*'") do id=$(echo $video | sed "s|url\='http://www.youtube.com/watch?v=\(.*\)&.*'|\1|") wget -O ALL/$id.flv "http://www.youtube.com/get_video.php?video_id=$id&t=$(curl -s "http://www.youtube.com/watch?v=$id" | sed -n 's/.*, "t": "\([^"]*\)", .*/\1/p')" done done

curl -s http://www.youtube.com/view_play_list?p=C492ACC54B43F77C | grep -o "url='http://www.youtube.com/watch?v=[^']*'"

finds nothing.

You have to use the GData API:

curl -s http://gdata.youtube.com/feeds/api/playlists/C492ACC54B43F77C | grep -o "url='http://www.youtube.com/watch?v=[^']*'"

So just http://gdata.youtube.com/feeds/api/playlists/$id

Comment by matthewbauer 357 weeks and 1 day ago

@matthewbauer: Does the GData API method retrieve single page if the playlist contains items more than a certain number? I'm getting 24 items although there are 40 in playlist.

Comment by alperyilmaz 311 weeks and 3 days ago

It looks like, maximum item per page is 25. So if you have lots of items in your playlist, you need to parse the following:

http://gdata.youtube.com/feeds/api/playlists/PLAYLISTID?start-index=26

http://gdata.youtube.com/feeds/api/playlists/PLAYLISTID?start-index=51

so on so forth

What about a for loop:

for i in 1 26 51 76 101; do curl -s http://gdata.youtube.com/feeds/api/playlists/PLAYLISTID?start-index="$i" | grep -o "url='http://www.youtube.com/watch?v=[^']*'" ; done
