List your Boxee queue

Might be able to do it in less steps with xmlstarlet, although whether that would end up being shorter overall I don't know - xmlstarlet syntax confuses the heck out of me. Prompts for your password, or if you're a bit mental you can add your password into the command itself in the format "-u user:password". Show Sample Output

Get the total length of all videos in the current dir in H:m:s

You're behind on your TV catch-up, but how far behind? This command tries to open mplayer against all files in the current dir. If it's a video file it will contain ID_LENGTH, which is summed and output in hours, minutes and seconds. Someone better at awk could probably reduce this down a lot. Show Sample Output
