RPM is a useful tool for both managing your
system and diagnosing and fixing problems. The best way to make sense of
all of its options is to look at some examples.
Perhaps you have deleted some files by accident, but you are not
sure what you deleted. To verify your entire system and see what
might be missing, you could try the following command:
If some files are missing or appear to have been corrupted, you
should probably either re-install the package or uninstall and then
re-install the package.
At some point, you might see a file that you do not recognize. To
find out which package owns it, enter:
rpm -qf /usr/bin/ggv
The output would look like the following:
We can combine the above two examples in the following scenario.
Say you are having problems with
/usr/bin/paste. You would like to verify the
package that owns that program, but you do not know which package
owns paste. Enter the following command,
rpm -Vf /usr/bin/paste
and the appropriate package is verified.
Do you want to find out more information about a particular program?
You can try the following command to locate the documentation which
came with the package that owns that program:
You may find a new RPM, but you do not
know what it does. To find information about it, use the following
rpm -qip crontabs-1.10-7.noarch.rpm
The output would be similar to the following:

Summary : Root crontab files used to schedule the execution of programs.
The crontabs package contains root crontab files. Crontab is the
program used to install, uninstall, or list the tables used to drive the
cron daemon. The cron daemon checks the crontab files to see when
particular commands are scheduled to be executed. If commands are
scheduled, then it executes them.
Perhaps you now want to see what files the
crontabs RPM installs. You would enter the
