written by: jlwallen•edited by: J. F. Amprimoz•updated: 7/4/2011

There are many ways to install an application on a Linux machine. For many the graphical front end of the package manager is all you need. But there are times when you will need to use the command line. For those times, rpm is a good system to know. This article will show you how to use rpm.

    What is rpm?

    RPM stands for Red Hat Package Manager because it was created for the Red Hat Linux distribution but is now used by others such as Mandriva and SuSE. RPM is both the file extension, as well as the command used to install the packages. So don't get confused when you are told to "rpm the rpm file". The rpm format has become the baseline format for the Linux Standards Base which is a consortium who's goal it is to develop a standard for all Linux distributions to follow.

    Basic Usage

    The rpm command is fairly simple to use, once you understand the various switches and arguments. The command structure looks like this:

    rpm [ACTION/OPTION] FILENAME.rpm

    There are two types of actions: Querying, Installing/Upgrading/Removing. A query option is used when you want to know if a package is installed on a machine and what version is installed. The install/upgrade/remove action is used to install, remove, or upgrade a package. NOTE: Any of the installing, upgrading, removing commands must be run as root. The query command can be run as a standard user.

    To check to see if a package is installed on your machine you would issue the command rpm -q package_name. Notice you do not add the "rpm" extension at the end of the package name. If you issue the command rpm -q gnome-terminal you might see the results:

    gnome-teriminal-2.24.2-2.fc10.i386

    If gnome-terminal was not installed on your machine you would see:

    "package gnome-terminal is not installed"

    Say you have downloaded an rpm file to install (We'll go with aterm-1.0.1-4.i386.rpm). If you want to install you would issue the command:

    rpm -i aterm-1.0.1-4.i386.rpm

    and the package would install. Running the above command however, will give you no feedback. I like to add a couple of switches so I know what is going on. By adding the v (for verbose output) and the h (for displaying "#" symbols for progression of installation) I would see something like you see below. First the command:

    rpm -ivh aterm-1.0.1-4.i386.rpm

    and now the output:

    Preparing... ################################################[100%]

    1: aterm ################################################ [100%]

    Once the installation is done you will be back at your command prompt.

    Now let's say you want to remove aterm. To remove a package with rpm you would use the "-e" switch like so:

    rpm -h aterm

    and aterm would be removed. NOTE: You can not use the "v" and "h" arguments with the "e" argument.
