    ps aux will show you the information (for the most part) but one thing you should learn for any computer is how to only get the most important information.

    You can find all this on `man ps` but it took me someone else showing me this for it to click.

    ps ax -o cpu,vsz,pid,comm | sort -n

    you can swap the `cpu` and the `vsz` to change what value is the sort value (vsz is ram usage). the pid is self explanitory, comm is the command that was used to start the processes.
    New to the internet, technical forums, or the hacker / open source community??

    I'm running Intel Pentium 4 CPU 3.06GHz, 2GB DDR2 RAM, GeForce FX 5200 graphics card. After having my system running for about 26 hours, I was playing a movie, running pidgin messenger, Azureus, Add/Remove Software, Brasero Disc Burner, Open Office, and 2 terminals. I wasn't actually using all those programs, just ran them to test my system. That got my system to lag (notice the hours). My system began to lag so quick that I couldn't even get to the terminal that was already prepared with the command "ps aux" so I had no choice to but to reboot again. After reboot, I ran the same programs as above and this time also ran Gimp and Kino and my system didn't lag at all. I really don't get it. I never had these issues while running Win7 for 20 days straight and that OS takes up so much extra of the system resources than Linux. However, while running those programs after reboot, I did use the "ps aux" command and this is what I got. Noticing there was no lag this time, I'm not sure if the output will be the same it was would be with the lag. But here is it anyways.
