As you've probably noticed - I am a Ubuntu noob (I just got it yesterday.)

I have installed some programs through Terminal before, about 5-10 - so using Terminal doesn't scare me. But, I'm getting a new computer soon (yes, yes, I know I should've waited and did this on the new computer instead, but I was so excited! I'm sure you can relate ;A;) and I've heard it's hard and time consuming to move apps over to another hard disk, and it would be easier just to install them again. So, I will... but I don't really remember what I have installed and want an easy way to do this.

Is there any way to have a list of installed programs in Terminal or somewhere - and possibly even the apt-get commands to reinstall?
