Yum Force Exclude List

While talking with my fellow colleague Darren Birkett about what seems a design limitation
of yum to not be able to force listing the excludes from yum. I had a
shoot to make a yum plugin to force listing the excludes.

Here is how it works :

root@centos5:~> grep exclude /etc/yum.conf
exclude=rpm*
root@centos5:~> yum install rpm-devel
Loading “installonlyn” plugin
Loading “changelog” plugin
Loading “chmouel” plugin
Loading “priorities” plugin
Setting up Install Process
Setting up repositories
Reading repository metadata in from local files
Excluding Packages in global exclude list
Finished
0 packages excluded due to repository priority protections
Parsing package install arguments
Nothing to do

rpm* is excluded, but if we use the environment variable FORCE_EXCLUDE
it will force it.

 root@centos5:~> FORCE_EXCLUDE=true yum install rpm-devel
Loading “installonlyn” plugin
Loading “changelog” plugin
Loading “chmouel” plugin
Loading “priorities” plugin
Setting up Install Process
Setting up repositories
Reading repository metadata in from local files
0 packages excluded due to repository priority protections
Parsing package install arguments
Resolving Dependencies
–> Populating transaction set with selected packages. Please wait.

—> Package rpm-devel.i386 0:4.4.2-47.el5 set to be updated

It will allow you to list the excluded rpm as well :

 root@centos5:~> FORCE_EXCLUDE=true yum list|grep rpm
rpm.i386 4.4.2-47.el5 installed
rpm-libs.i386 4.4.2-47.el5 installed
rpm-python.i386 4.4.2-47.el5 installed
redhat-rpm-config.noarch 8.0.45-22.el5.centos base
rpm-build.i386 4.4.2-47.el5 base
rpm-devel.i386 4.4.2-47.el5 base
root@centos5:~> yum list|grep rpm
rpm.i386 4.4.2-47.el5 installed
rpm-libs.i386 4.4.2-47.el5 installed
rpm-python.i386 4.4.2-47.el5 installed
redhat-rpm-config.noarch 8.0.45-22.el5.centos base

See the README.txt in the rpm file to see how to use/install it.

How to get bright LS colors on Redhat with dark background

Something that i haven’t find via goole. By default on RedHat (and derivatives) if you get a dark background the colored ls will be seen really humm bold from a xterm (since i guess there default gnome-terminal has been configured to have a white background ).

The solution is to

cp /etc/DIR_COLORS /etc/DIR_COLORS.xterm

or to redefine your dircolors to get the /etc/DIR_COLORS files instead of /etc/DIR_COLORS.xterm in your shell init configuration.
