General Notes

  • This is an Unofficial Fedora Core 4 Starter Guide. It is not associated with Fedora and RedHat, inc.
  • Guide is tested on a default "Personal computer" installation of the Fedora Core 4 with default packages.
  • If you see a bluish box, this means you have to execute the commands in Terminal mode (Applications -> System Tools -> Terminal) or use the content of that box as mentioned in some other instructions.
  • To reduce typo mistakes, copy and paste the commands into Terminal mode (right click on the commands -> "Copy" or "Paste". You can also use Ctrl+C to copy and Shift+Insert to paste it)
Note: You must run these commands as root. Before you get to do anything you must type 
su -
And enter your root password.

Add-On Applications

[edit]

How To use Yum

Yum is a very powerfull package manager. yum will resolve dependencies for you and makes installing applications a breeze. yum also searches, removes, and lists packages for you. 

usage: yum [options] < update | install | info | remove | list |
clean | provides | search | check-update | groupinstall |
groupupdate | grouplist | groupinfo | groupremove |
makecache | localinstall | erase | upgrade | whatprovides |
localupdate | resolvedep | shell | deplist >
options:
-h, --help            show this help message and exit
-t, --tolerant        be tolerant of errors
-C                    run entirely from cache, don't update cache
-c  [config file]     config file location
-R  [minutes]         maximum command wait time
-d  [debug level]     debugging output level
-e  [error level]     error output level
-y                    answer yes for all questions
--version             show Yum version and exit
--installroot=[path]  set install root
--enablerepo=[repo]   enable one or more repositories (wildcards allowed)
--disablerepo=[repo]  disable one or more repositories (wildcards allowed)
--exclude=[package]   exclude package(s) by name or glob
--obsoletes           enable obsoletes processing during updates
--noplugins           disable Yum plugins

From a first look this can look rather intimidating, but this is rather easy.

Examples:
  • To seach for a application

Yum will search all your enabled repos and tell you where you can obtain the package from 

yum search application_name
  • Yum can list all available packages from your enabled repos and tell you where you can obtain the package from: 
yum list available
  • To find out more info about some package 
yum info application_name
  • Installing applications

Inastalling is as easy as 

yum install application_name
  • Listing rpms

yum can list installed rpms for you from the repos you have enabled 

yum list extras
  • Removing rpms

Yum can remove a application and the dependenciesit installed with tat application. it will not remove depenencies if another application installed needs them. 

yum remove application_name
  • Updating the system

Yum can update the system for you with out user interact if you want it to. 

yum update
  • Not sure if you have upates? 
yum check-update
  • Local install

downloaded a rpm and cannot install it with rpm because of dependencies? 

yum localinstall /path/to/the/rpm
Happy yumming...

root	ALL=(ALL) ALL
  • Add your username underneath where it says root and copy the rest of the line as is: 
# User privilege specification
