Installing application in centos 7 minimal

Hi,
I’m very new to Linux so I’m confused and feels very strange with its operations . I installed centos 7 minimal (approx 700mb in size) but now I want to install few software’s like k3b burner live usb creator etc I tried to make it executable from property , its not working … And I don’t see the option ‘system’ from start menu , I have only ‘system tools’ instead… Friends please help me to sort out the problems I feels there I have lots of problem with Linux … Please give me a step by step instruction for it…
Sorry for my bad English
Thanks…

Hi Arun,

To install k3b on your system simply open terminal and run the following command with administrative privileges:

# yum install k3b

that is all. If you need more software first search for a package name. For example the below command will show more CD/DVD burning related software:

$ yum search burning
============================= N/S matched: burning 
brasero.x86_64 : Gnome CD/DVD burning application
k3b.x86_64 : CD/DVD/Blu-ray burning application
k3b-extras-freeworld.x86_64 : Additional codec plugins for the k3b CD/DVD burning application
mstflint.x86_64 : Mellanox firmware burning tool
mytharchive.x86_64 : A module for MythTV for creating and burning DVDs

  Name and summary matches only, use "search all" for everything.

Pick one and install it by using install option as shown above.

Hope this helps

Lubos
