How to install softwares in linux, are they as simple as clicking the install button in windows.
I have openSUSE 10.3 (i586) Linux 2.6.22.5-31-default i686 .
I have downloaded xmms but am at sea about installations in Linux

Welcome to LQ!!

On average, SW installation on Linux is EASIER than on Windows. Most of what you will need is available using the package manager. It's in the menus under something like "install/remove applications". (On SUSE, the program is "YAST" or maybe "YAST2")

On my system (Arch) xmms is available in the package manager--I'll bet SUSE has it also.

I have installed this distro from a live cd and it does not have xmms
can u help me
I have downloaded xmms but cannot install

You would be better off installing throug Yast.

Go to Yast - Software - Install and Remove. Click the Administrator button and enter the root password. Wait a short while, and in the screen which comes up, in the filter drop-down selection, select package groups. You will be shown a list of the packages in the OpenSuse repository. The list will show you which you already have installed.

Just left-click in the checkbox for each package you want to install and click on the Accept button. Yast will do the rest.

If you insist on installing downloaded packages, all you need to do is open a console and cd to the folder where the .rpm is located. Then give the command 'rpm -i <packagename>' (without quotes: substitute the name of the package for <packagename>).

When the package is installed, then you must run /sbin/SuSEconfig. If you don't, then Yast will ignore any manually installed package: i.e. Yast won't update it when you run updates.

use rpm -ivh xmms* in the terminal to just install xmms
