YUM

Install from cd again

After installing redhat it discards the cd and you are left to only update from the net. You can re-enable the cd again. Edit the file /etc/yum.repo.d/mycd.repo.

If the file does not exist then create it.

Cleanup

yum clean packages

Eliminate any cached packages from the system. Note that packages are not automatically deleted after they are downloaded.

yum clean headers

Eliminate all of the files which yum uses to determine the remote availablility of packages. Using this option will force yum to download all the headers the next time it is run.

yum clean oldheaders

Eliminate the old headers that yum no longer needs to determine the remote availablility of packages.

yum clean [all]

Runs yum clean packages and yum clean oldheaders as above. Mount your RH6 cd in /mnt/cdrom and do yum update. Please delete all other files from /etc/yum.repo.d directory.

Extract files from rpm

To extract an individual file from an rpm package without installing the rpm: 1. Use rpm2cpio or rpm -qpl to list files and full paths in the package: rpm2cpio package | cpio -t

You need the full path name of a file to extract it in step 2.

2. Use rpm2cpio to extract a file. Run this command from your home directory or /tmp in order to avoid overwriting any current system files.

rpm2cpio package | cpio -iv --make-directories full-path

This creates the full path in the current directory and extracts the file you specified.

3. If you just want to convert it to a cpio archive, use

rpm2cpio package > cpio-archive-file

RPM mass uninstall

If you want to remove a list of RPMs without typing each on separately, you can use the xargs command with rpm. Here are the commands and output from a session where I wanted to delete several RPMs at once. First, I used rpm -qa to find all the xine RPMs. When I verified the list, I passed the list to xargs to execute an rpm -e on each of them. The final rpm -qa verifies that they have all been uninstalled.

artifact:~/datacore/suse-7.3/xine # rpm -qa | grep xine
xine-lib-0.9.7-0
xine-lib-aa-0.9.7-0
xine-lib-alsa05-0.9.7-0
