Hey guys, I'm a total noob at anything to do with programming but for some reason my computer uses Ubuntu. I want to download this program (http://www.soimort.org/you-get/) but I have no idea what these commands mean and when I tried them in Terminal, errors came up. I'm assuming maybe I don't have Python? But I thought it was just a programming language. Can anyone help? It will be much appreciated, thanks.

Commands? If you're speaking of:
$ you-get http://youtu.be/sGwy8DsUJ4M

It's something you would insert into a Console/Terminal.
Looking at it, the pre-requisites are pretty laid out plain and simply. Ubuntu is a Linux software so you should know how to access the Terminal and make sure you have Python installed onto your Operating System.

If you don't understand these Commands, you should probably read up on Linux.

All of the commands can be done through your Ubuntu OS Terminal.

Also, check out buckysroom.org - It's a developers social network so if you have any questions or need help register, and talk to people. Everyone is willing to help.

thanks!
