RPM

Check for a particular RPM

If, for example, a program you want to install calls for GTK to also be installed, you can check if you have RPMs for this installed by issuing the following command:

rpm -qa | grep gtk

get package information

This will get detailed information about an RPM:

rpm -qpi the_package.rpm

what does package depend on

This will show what files are needed by the gaim RPM installed on your system.

rpm -q --requires gaim-0.75-0.9.0

what package does a file belong to

The following command will show you what package a file came from.

rpm -q -f /usr/lib/libssl3.so

rebuild source RPM

To install an RPM for a different distribution, run the following command:

rpm --rebuild x.src.rpm

This usually places the new RPM in /usr/source/rpm/

make uninstalling a package more automatic

To uninstall package with a little less effort, you can use the following one-liner. This example will uninstall everything with 'mozilla' in the package name. You should be careful with this particular one. The '--nodeps' will override RPM warnings about dependencies. Other packages may be effected.

rpm -qa | grep mozilla | xargs -n1 -p rpm -e --nodeps

Misc.

use wget to download packages

If you're updating a lot of packages and you need to install manually, you can use wget to automate the package download process somewhat. This comes in handy when you're, say, updating to a higher version of KDE, for example. To get every packages in a directory, you would use the following wget command:

wget -c -r -np http://some.kde-mirror.org/new_version/
