I am using Ubuntu 12.04 right now. If I use the command sudo apt-get dist-upgrade will that upgrade my Ubuntu to 12.10? Does that mean I won't be using the LTS version after that? I don't want to use Ubuntu 12.10 because I've already tried it and it's very heavy for my netbook.

You can read the man-page of apt-get to see what each command do.
Open the manual
man apt-getFind the section dist-upgrade and read
dist-upgrade
in addition to performing the function of upgrade, also intelligently handles changing dependencies with new versions of packages; apt-get has a "smart" conflict resolution system, and it will attempt to upgrade the most important packages at the expense of less important ones if necessary. So, dist-upgrade command may remove some packages. The /etc/apt/sources.list file contains a list of locations from which to retrieve desired package files. See also apt_preferences(5) for a mechanism for overriding the general settings for individual packages

In order to upgrade Ubuntu to a newer release you have to run in terminal
sudo do-release-upgradeWe read from the man-page
man do-release-upgrade3DESCRIPTION
Upgrade the operating system to the latest release from the command-line. This is the preferred command if the machine has no graphic environment or if the machine is to be upgraded over a remote connection
No, sudo apt-get dist-upgrade will not upgrade to a new Ubuntu release. It will just install available updates for the Ubuntu release you already have installed.
Unlike sudo apt-get upgrade it may install new packages or remove installed packages if that is necessary to satisfy dependencies. So be careful when using it.
If you do not want to upgrade to non-LTS versions, follow these steps:
Open Ubuntu Software Center.
Go to Edit -> Software Sources.
Go to the Updates tab and make sure you have selected For long-term support versions in the Notify of a new Ubuntu version.
Open a terminal and run
sudo apt-get update(just to be sure :) ).Now, when you run
sudo apt-get dist-upgradeit'd be upgraded to the next LTS version and not non-LTS versions.
you cannot jump from 12.04 to 13.04 directly you would have to have update manger set to normal then do
sudo apt-get dist-upgradeor
sudo do-release-upgradethe difference between the commands is that dist-upgrade wants you to change your config files during the upgrade
they both will upgrade your dist when the time comes sudo apt-get upgrade only upgrades the software on your system it does not install or remove packages like dist-upgrade.
