Linux List All Outdated Packages Which Could be Updated and Applied to System
Q. How can I know what packages are available for binary update under Fedora / RHEL / CentOS Linux version 5 server? How do I list all outdated packages? How do I apply update / patches to system?
A. CentOS / RHEL / Fedora Linux version 5 and above supports yum command (yum is an interactive, automated update program which can be used for maintaining systems using rpm). It can list all packages which could be updated from a shell prompt.
First, Login as the root user
Type the following command at shell prompt to list all outdated packages:
# yum list updates
Output:
Loading "installonlyn" plugin Loading "rhnplugin" plugin Setting up repositories rhel-x86_64-server-vt-5 100% |=========================| 1.2 kB 00:00 rhel-x86_64-server-5 100% |=========================| 1.2 kB 00:00 Reading repository metadata in from local files Updated Packages tzdata.noarch 2007k-1.el5 rhel-x86_64-serv
You can also try to locate specific packages:
# yum list updates package-name
# yum list updates "*apache*"
# yum list updates "regex"
To updated packages, enter:
# yum update
A note about RHEL version <= 4.x
RHEL version 4.0 and below uses up2date command. It has -l option to show you what package updates are available for download and installing the same.
# up2date -l
To check for and update all RPM(S), enter:
# up2date -u

Another way for SuSE 10.x user is to configure Online Update applet on taskbar:
1. Right click Auto-Update applet, select “Configure Applet”
2. Check checkbox named “Show available upgrades when backend provides them (for experts only)”
This will allow Online-Update service to look for installable upgrades packages.
I uses the same method to resolve conflict when upgrading Amarok iterative updates in YaST.
Thanks
