Introduction

RPM is a command-line utility for managing packages on Unix/Linux systems. It allows you to install, query, update, verify and remove RPM packages.

It is the default package manager for Red Hat based systems and only works with the .rpm format. You can install such packages using the rpm or the yum command.

In this article, you will learn how to use rpm commands with easy-to-follow examples.

Prerequisites

• A system running Linux.

• Access to the command line/terminal.

• Access to root or an account with sudo privileges.

Linux RPM Command Syntax

The basic syntax for the command is:

sudo rpm [option] [package_name]

To see a full list of command options, run:

sudo rpm --help

RPM Command Options

Below you will find the most popular command options used with the rpm command and their meaning.

-e, --erase	Remove (uninstall) package(s).
-h, --hash	Print hash marks as the package installs.
-i, --install	Install package(s).
-l, --list	List files in a package.
-q, --query	Query package(s).
-s, --state	Display the state of the listed files.
-U, --upgrade	Upgrade package(s).
-v, --verbose	Provide more detailed output.
-V, --verify	Verify package(s).

RPM Command Examples

The rpm command is simple to use and allows combining multiple options to customize each query. Explore some of the most commonly used commands listed below and try out how they work with a sample package.

Install RPM Packages

To install RPM packages with the rpm command, use the syntax:

sudo rpm -ivh package_name

The command includes the options:

• -i (install)

• -v (verbose output)

• -h (print hash marks to show the installation process)

Before installing, you need to download the appropriate file. The package has to be compatible with the system architecture of the machine. 

Note: To download packages, use the curl or wget command.

For instance, to install the MySQL package, you run:

sudo rpm -ivh mysql80-community-release-el7-5.noarch.rpm

To install an RPM package without previously downloading it, provide the URL:

sudo rpm -ivh package_URL

For example:

sudo rpm -ivh https://dev.mysql.com/get/mysql80-community-release-el7-5.noarch.rpm

Upgrade RPM Packages

RPM upgrades a package by uninstalling the current version and installing the latest one. 

The command for upgrading a package is:

sudo rpm -Uvh package_name

• -U (upgrade)

• -v (verbose mode)

• -h (print hash marks to show upgrading process)

To upgrade MySQL, use:

sudo rpm -Uvh mysql80-community-release-el7-5.noarch.rpm

If the new version requires additional dependencies, you must install them manually. RPM lists the missing dependencies in the output after running the command.

To ignore the message and update without the dependencies, add the --nodeps option to the command:

sudo rpm -Uvh --nodeps package_name

Remove RPM Packages

Remove RPM packages using the -e (--erase) option:

sudo rpm -e package_name

To see the verbose output, add the -v option to the command:

sudo rpm -ev package_name

To delete an RPM package without removing dependencies, add --nodeps:

sudo rpm -ev --nodeps package_name

For example, to remove MySQL without removing its dependencies, you run:

sudo rpm -ev --nodeps mysql80-community-release-el7-5.noarch

Display Package Information After Installing

To see available information about an installed RPM package, use the -qi option, which instructs RPM to query info:

sudo rpm -qi package_name

The output displays the installed information, package version, and a short description.

To do so for MySQL, run:

sudo rpm -qi mysql89-community-release-el7-5.noarch

Display Package Information Before Installing

The command for displaying information about a package prior to installation is:

sudo rpm -qip package_name

The command includes the options:

• -qi (query information)

• -p (query/verify a package)

To display information before installing the MySQL package, use the command:

sudo rpm -qip mysql89-community-release-el7-5.noarch

Check Package Dependencies Before Installing

RPM allows you to check the dependencies of packages prior to installing them on the system. Bear in mind, you need to have the RPM package downloaded locally to see a list of dependencies.

The command for doing so is:

rpm -qpR package_name

The options are:

• -q (query format)

• -p (query/verify a package)

• -R (list package dependencies)

For example, to list the dependencies for installing the MySQL RPM package, you run:

rpm -qpR mysql80-community-release-el7-5.noarch

Verify Packages

Verifying packages means comparing metadata from the RPM database with the information from the installed files.

You can verify all installed packages using the command:

sudo rpm -Va

• -V (verify)

• -a (all)

To verify a specific package run:

sudo rpm -Vp package_name

• -V (verify)

• -p (package)

Verify the installed MySQL package with:

sudo rpm -Vp mysql80-community-release-el7-5.noarch.rpm

Find Manual Pages

To list available documentation related to an installed RPM package, use the -qdf option:

sudo rpm -qdf package_name

The command options are:

• -q (query format)

• -d (list documentation files)

• -f (query package owning file)

To find manual pages for MySQL, use the command:

sudo rpm -qdf mysql80-comunity-release-el7-5.noarch.rpm

List All Files of an Installed Package

See detailed information about a package by listing all its files, use the -ql option and instructs RPM to query list:

sudo rpm -ql package_name

For example, to list files of the sample MySQL package, you run:

sudo rpm -ql mysql80-community-release-el7-5.noarch

List Installed Packages

List all of the installed RPM packages on the system by running the following:

sudo rpm -qa

The command includes the -qa option, which instructs RPM to query all.

List Recently Installed Packages

To display a list of all the recently installed packages, use the -qa (query all) option along with the --last attribute:

sudo rpm -qa --last

The output lists all the installed RPM packages, ordering them by the latest package on top.
