Some useful RPM command

Redhat or Fedora using RPM to manage package installation. RPM will report package dependencies if the installation failed. However, I found YUM is much more easy than RPM in install and uninstall operation. However, there are some useful aspect of using RPM.

# To list all installed packages
rpm -qa

# To query a package information and dependencies packages
rpm -qilR 

# To query which package require a package
rpm -q --whatrequires 

# To query which package provide the file
rpm -q --whatprovides 

# Test package installation
rpm -ivv --test
