Ok, I'm going to assume your using fedora 7, and that you are using the default setup.
Many of the instructions you will be given in this forum take the form of things to type in a terminal. A terminal is similar to the old DOS prompt.
To open a terminal, click on applications go the system tools, then click on terminal. You should see something like this
. Yours will not be identical, I have customized the look of my system significantly.
Normally, after you have logged on you won't have the ability to install programs. Your account doesn't have permission to. So, we are going to log in to this terminal as the administrator.
su stands for super user. The super user is the administrator of the system, and the only one allowed to install programs. After entering that, you will be asked for your password. This is the root password you setup when you installed fedora. Enter that, and hit return. Don't worry that nothing is appearing as you type your root password, it's not supposed to show up. You should now have something like this
Notice at the beginning of the bottom line, before the @ symbol that it now says root. Anything you tell the system to do from here will be done as root. That means you can install programs, modify important ways the system functions, etc...
There are several ways to install things in fedora. The easiest is to use a program called yum
goes online and gets the packages you need to make the program you want to install run.
Now, say we want to install a free game like battle for wesnoth. First we specify what program we are talking to, in this case yum. Then we add a space, so it knows we are now telling it what kind of action we want it to take. We then specify the action. Then another space, and we tell it what to perform that action on. So, we end up with this.
yum install wesnoth
Yum then goes and gets not only that package, but anything else we didn't have required to run wesnoth. Then it asks you if this is ok, and installs the program.
I tried to simplify this as much as possible, as such I had to leave ALOT out.
