BleepingComputer.com: Installation

I am new at Linux
What i want to learn is how to install programs,songs...etc at Linux.I use Fedora Core 5.They told me to use yum but if doesnt work
actually it works but it works only for programs that I can install from the Add/Remove Software.

if=it

What are you trying to install? For things that you can't get from YUM, you will probably have to become root and chmod them and then ./programname. That's how I have to do it at least.. Hope this helps.

Yum is to install new programs and check for updates to existing programs installed by yum. Also not all programs are part of the core Yum repository. You can also use Dag which may contain other programs that you can install. To add Dag to yum, do the following:

Type the following:

cd /etc/yum.repos.d
vi dag.repo

Add the text in the quote below to dag.repo and save the file by typeing :wq and pressing enter.

Now you need to install the dag key by typeing the following and pressing enter:

rpm --import http://dag.wieers.com/packages/RPM-GPG-KEY.dag.txt

Now when you use Yum it will also check the Dag repository.
When you say new songs I am not sure what you mean?
