How to Install or Remove an RPM Package
Article to be downloaded article to be downloaded Many GNU/Linux distributions make use of the well-known Redhat Package Manager (RPM) mechanism for installing and uninstalling software.Almost all Linux users will at some point feel the need to either install more software on their computer or uninstall an application that was pre-installed with their distribution of Linux.While installing new software may be a time-consuming and error-prone process, RPM simplifies the process by condensing everything into a single command.
- 1 Download the RPM package that you want to use. Many RPM depositories exist on the Internet, however if you are seeking for Red Hat RPM packages, you can find them here: http://www.redhat.com/rpm/. The Red Hat Enterprise Linux installation media, which contain a large number of RPMs that may be installed
- The basic RPM repositories that come with the YUM package management are as follows:
- EPEL (Extra Packages for Enterprise Linux) is a collection of high-quality add-on packages for Red Hat Enterprise Linux
- it is maintained by Red Hat.
- 2 Download and install the RPM package. Once the file has been downloaded, you have two choices: Double-click the package to open it. During the procedure, a package management window will emerge, with instructions to take you through the steps.
- Open a terminal window and type the command rpm -i *package location and name* (without the spaces in between the quotes)
- 1The rpm -i command syntax is listed below.
- 2 Install-specific options:
- -h (or -hash) Print hash marks (″ ″) during install
- -test Perform installation tests only
- -percent Print percentages during install
- -excludedocs Do not install documentation
- -includedocs Install documentation
- -replacepkgs Replace a package with a new copy of itself
- -replacefiles Replace files owned by another package
- -force Ignore package and file conflicts
- -noscripts Do not execute pre- and post-install scripts
- -prefixRelocate package toif possible
- -ignorearch Do not verify package architecture
- -ignoreos Do not verify package operating system
- -nodeps Do not check dependencies
Use as the FTP proxy
- -ftpportUseas the FTP port
- The RPM package must be installed first. The following are the two possibilities once the file has been downloaded: The package should be opened by double-clicking on it. During the procedure, a package management window will emerge, with instructions to take you through it.
- Enter the command rpm -i *package location and name* (without the spaces in between) in a terminal window.
- Inquire about something There are 200 characters remaining. Include your email address so that you may be notified when this question has been resolved. Advertisement submissions are welcome. It will only be necessary to force an installation in rare occasions. This may be accomplished by using the -force parameter to the rpm command. – This will only work if you use the command prompt.
- Using the argument -U (update) rather than the parameter -i (install) ensures that you are installing the most recent version of the RPM.
- Some packages will have dependencies on other packages.
- All this implies is that you will need to install another package in order for the desired one to function properly.
- Ogle, a free and open-source DVD player, is an example of this.
- Ogle does not have the ability to play DVDs on its own
- instead, it requires the installation of a few additional applications in addition to the basic Ogle package. If the rpm contains dependencies and you don’t care about fulfilling them, you may also use the -nodeps option to avoid satisfying them.
Thank you for submitting a suggestion for consideration! Advertisement It is possible to overwrite certain data that is essential for another software to function properly in specific circumstances. Always use caution when adding or removing anything from your computer’s system.

How to install and uninstall RPM package on Linux
The following are the procedures for installing and uninstalling the RPM package on Linux: What is the best way to install an RPM package?The installation of the RMP package may be accomplished with the help of the rpm program.Run the following command to complete the task.
Specifically, the file name of the RPM package you wish to install is your-package.rpm, and it is often located in the current directory.During the installation process, the following warnings or prompts may appear: … in confrontation with…It’s possible that some of the files in the package to be installed will overlap with the files already there.It is not capable of being installed successfully by default.
RPM — force – I am capable of being forced into existence….is required by……is not currently installed…It is recommended that you disregard this information since this package requires software that you do not have installed in order to use RPM — nodeps – In other words, RPM – I — force — nodeps can disregard any and all dependency and file issues, regardless of which package is being used.However, the functionality of this type of software package cannot be guaranteed.
2.How to set up the system.The src.rpm package contains the source code.Some packages have the suffix Src.Rpm at the end of them.
These packages are RPM packages that include the source code for the application..Compilation is necessary throughout the installation process.There are two methods for installing such packages, both of which are described here.Method 1: Run RPM – I to install your package.src.rpm go to /usr/src/redhat/SPECS BP – Rpmbuild – the specifications file with the same name as your package is called your package.specs Build your package in a directory with the same name as your package by copying it to the CD-ROM, the SRC-directory, and the RedHat-directory.Compiling common source code software is similar to this phase, except that you can include parameters.
- create a make an installation The RPM – I you package is executed in Method 2 1.
- Cd into the directory /usr/src/redhat/SPECS and run src.rpm 2.
- The first two stages are identical to those in approach one.
- The third step is to use Rpmbuild to create a specifications file with the same name as your package.specs.
- As of right now, in /usr / SRC / RedHat / RPM in the i386 directory is where the problem resides.
- For example, depending on the individual package, it may be i686, noarch, or any other number of other options.
- There is a new RPM package in this directory, which is a built binary file, and it may be installed.
- To complete the installation, run RPM – I new package.rpm from the command line.
Uninstalling the RPM package is the third step.RPM –e package name allows you to specify a name for a package that contains the version number and other information, but it does not allow you to specify a suffix.Rpm For example, if you want to remove the software package proftpd-1.2.8-1, you can follow the steps in the following format: rpm -e proftpd-1.2.8-1 rpm -e proftpd-1.2.8 rpm -e proftpd-1.2.8 rpm -e proftpd- rpm -e proftpd- It is not permitted to be in the following format: rpm -e proftpd-1.2.8-1.i386.rpm rpm -e proftpd-1.2.8-1.i386.rpm the following commands: rpm -e proftpd-1.2.8-1.i386 rpm -e proftpd-1.2 rpm -e proftpd-1.2.8-1.i386 There are several problems or alerts that appear from time to time: Therefore, this program is required by other applications and cannot be unloaded at the user’s discretion You may use the RPM – E — nodeps command to force remove a package.4.How to obtain the files in the RPM package without having to install them Using the tools rpm2cpio and CPIO: rpm2cpio xxx.rpm |cpio -vi rpm2cpio xxx.rpm |
cpio -idmv rpm2cpio xxx.rpm |cpio -extract -make-directories |cpio -extract -make-director The argument I is the same as the parameter extract, which indicates that it is used to extract a file.The letter V denotes the procedure of execution.D is the same as make directory, which implies that a directory is created in the package according to the path of the file that was originally in it.
The letter M indicates that it is necessary to keep the file up to date.3.Obtaining information about the RPM package’s files and other information All of the examples in this section presume that the package mysql-3.23.54a-11 is being used.
1.Which RPM packages are currently installed on my system?RPM – QA displays a list of all the packages that have been installed.
If you wish to identify all of the installed packages that include a specific string, you may use the following command: SQL rpm -qa |grep sql 2 SQL rpm -qa |grep sql 2 SQL rpm -qa |grep sql 2 The best way to find out the complete file name of a software package Q – Revolutions per minute MySQL can obtain the entire name of the MySQL package that has been installed on the system, which can then be used to obtain the current version of the software package.You may learn more about this by looking at this example.mysql-3.23.54a-11 3.
- In what location are the files contained within an RPM package installed?
- RPM – the name of the QL package You should take note that this is the name of the package that does not contain the.
- RPM is an abbreviation for revolutions per minute.
- With this in mind, the MySQL or mysql-3.23.54a-11 packages are the only ones that may be used in place of the mysql-3.23.54a-11.rpm package.
- If you only want to know where the executable program is located, you may use which, as in which mysql, to find out.
- Fourth, what kind of files are contained within an RPM package Software that has not been installed on the computer yet.
Use RPM – QLP * *.RPM – QLP * *.It is also possible to utilize RPM – QL * * with an installed package.5.How can I find out what version of a software package I’m using and how it’s being used?
A package that has not yet been installed on the system.Make use of RPM – QIP * *.You may also use RPM – Qi * * * to install a software package that has already been installed.6.Which package included a program, or which package contained a software that was installed by another package When you run RPM – QF ‘whose program name ‘it returns the whole name of the package RPM – QIF – RPM – QIF ‘which program name’ returns information about the package that was specified in the query.
- RPM – QLF ‘which program name’ returns the file list of the package Take note that this is not a quote mark, but rather the letter ‘, which is located in the top left corner of the keyboard.
- Use RPM – qilf to simultaneously output package information and a file list, which is particularly useful.
- How do I find out which package has installed a file or which package contains a file?
- It is important to note that the approach in the preceding question only applies to executable programs, but the following method not only can but also does apply to executable programs.
- It can be used for executable programs, but it can also be used for any other type of file.
- The first need is that you know the file name.
To begin, obtain the whole path to the software.You can start with where is or which and then move on to RPM – QF.Using the following example: whereis ftptop ftptop is located at ftptop:/usr/bin/ftptop /usr/share/man/man1/ftptop.1.gz rpm -qf /usr/bin/ftptop /usr/share/man1/ftptop.1.gz proftpd-1.2.8-1 rpm -qf /usr/share/doc/proftpd-1.2.8/rfc/rfc0959.txt proftpd-1.2.8-1 rpm -qf /usr/share/doc/proftpd-1.2.8/rfc/rfc0959.txt proftpd-1.2.8-1 Here is the quickest and most straightforward method of installing and uninstalling Linux rpm Packages] mount /dev/cdrom /mnt mount Packages] mount /dev/cdrom /mnt mount Packages] install zip-3.0-1.el6.x86 64 with rpm -ivh zip-3.0-1.el6.x86 64 V is for visualizing.

Maintaining Software Using RPM (Red Hat Package Manager)
- This versatile software manager may be used to create and install individual software packages as well as to question and validate them. It can also be used to update and delete software packages. RPM packages are composed of an archive of files together with package metadata such as the package name, the version of the package, a description, and information about other RPM packages that are dependent on the RPM package in question. RPM is a general-purpose tool that is not limited to Red Hat. RPM is also used by a large number of other current distributions, including Ubuntu and SuSE. The following are some of the advantages of utilizing RPM: Software distribution, installation, updating, and removal have all been simplified.
- The following is ensured: required software is installed on the system
- prerequisite software version compatibility is maintained
- When an RPM is updated, locally-modified configuration files are not clobbed
- if a package is subsequently removed, locally-modified configuration files are preserved with a ″.rpmsave″ suffix. When an RPM is updated, locally-modified configuration files are not clobbed.
Certification that the installed program has not been edited, corrupted, or changed in any manner is made possible by this method.
- The ″/var/lib/rpm″ directory is where RPM stores information about the packages that have been installed. The RPM tool includes the following components: a custom database containing information about all software installed on the system, collected from the individual RPMs
- a custom database containing information about all software installed on the system, collected from the individual RPMs
- and a custom database containing information about all software installed on the system, collected from the individual RPMs.
- The rpm package executable ″/bin/rpm″
- Internet-accessible repositories of RPM packages that are currently available
Types of RPM Packages
Packages in the RPM format are divided into two categories: source and binary.The filename of a source RPM always ends with the string ″.src.rpm,″ which makes it easy to distinguish it from other RPMs.In addition to the original application source code files, source RPMs contain scripts that allow the code to be recompiled automatically, to be installed automatically, and to be uninstalled automatically.
A source RPM does not contain any executable files for end users.Most of the time, only programmers are interested in a source RPM.The end-user components of an RPM are contained within a binary RPM.The contents of binary RPM files are identified by their filenames, which indicate the host architecture.
Consider the following binary RPM file: It contains files that can only be accessed by a 64-bit Intel X86 architecture processor.Other popular architecture options include ″i386″ for Intel hosts that are 32-bit in nature.In certain cases, binary RPMs can be installed on any CPU architecture since their files are compatible with any host; an example of one of these ″.noarch.rpm″ packages is the ″tzdata″ RPM, which provides information on timezones throughout the world.You will need the most recent binary RPM for a package in order to update your system with the most recent version of that package.
RPM Naming Scheme
- Each RPM package is contained in a single file, which is called an RPM. There are various fields in the filename that allow you to completely identify the contents of the package. However, while the RPM tools themselves do not rely on the filename in and of itself, you should be familiar with the naming convention in order to better identify and download the appropriate package. Listed below is an example of an RPM filename: This RPM contains the BASH shell (often known as ″/bin/bash″). The filename is made up of various components, as follows: -.rpm, where: is the name of the application or package to be installed The author of the software is generally the one who assigns it. According to our hypothetical example, the developers decided to call their product ″bash″ for reasons that they thought were entertaining. version] This field specifies the version of the program is contained within the RPM. The creator of the software has set a numerical value to the variable. Using the number, one may verify which version of the author’s sources was used to build the RPM, which is useful for debugging. However, it does not specify which version of the author’s source files are being used, but rather whose edition number the RPM file itself has. It is possible that an updated RPM will be released in order to provide a patched version of the author’s original program. It is not necessary for the patch to have originated from the original developer, so the RPM is incremented instead of
- describes the contents of the RPM and indicates whether this file contains the product source (a ″.src.rpm″), architecture-independent files (a ″.noarch.rpm″), or files that can only be installed on a specific host type (a ″.sh.rpm″ will work only on a STRONGHOLD embedded processor)
It should be noted that the original author retains rights over the work, as does whomever developed the RPM.
Understanding RPM Versions
The RPMandfields are not necessarily purely numeric, and they may contain characters other than regular numbers in addition to digits.Version ″10″ and version ″10a″ of the same package are frequently seen in different locations.It might be difficult to determine which version is the most recent at times.
As an example of how RPM internally compares version and release numbers, consider the following: 1.Remove the ″.rpm″ suffix as well as the prefix.The rpm package named ″bash-3.1-16.1.x86 64.rpm″ will be renamed ″3.1-16.1,″ and the rpm package named ″bash-3.1-16.5a.1.x86 64.rpm″ will be renamed ″3.1-16.5a.1.″ 2 Until a digit is met, compare the remaining strings character by character, left to right.3 If the characters are different, the RPM that is more recent is determined by which character appears later in the collating sequence.
3) When you come across a digit, turn the complete sequence of digits into a single binary integer.In this example, the two letters ″16″ are merged to form a numerical value equal to sixteen (16).The binary numbers obtained as a consequence of this process are compared, and the bigger value indicates the more recent RPM.As a result, an RPM with the prefix ″0010″ is more recent than one with the prefix ″9.″ Steps 2 and 3 are done as many times as necessary until a significant change is observed.
Installing and Removing Files
Please keep in mind that often only one or two RPMs may be inserted at a time.When installing later versions, the ″-U″ (update) RPM function is typically used instead of the ″-i″ (install) RPM function.The kernel RPMs are one of the most common deviations to the one-RPM rule.
On a typical system, several versions of kernels are installed; RPM maintains a list of which RPMs may have multiple versions of kernels installed.When numerous versions of a package are installed, you must properly specify the package name and version in order to uninstall one of them.Having both the 32-bit ″.i386″ and 64-bit ″.x86 64″ RPM packages installed to support both 32-bit and 64-bit programs is standard on the x86 64 architecture.Normally, RPM does not display the architecture of a package when a query is run, but you may force it to reveal it explicitly.
Installation and Removal
Rpm -i -install is an abbreviation for Rpm -i -install (install new RPM; error if already installed) rpm -U -upgrade is an upgrade command (delete existing RPM, if any; install new) speed -F -refreshen (update RPM only if package already installed) rpm -e -erase rpm -e -erase (remove, delete, expunge) Typical Alternatives Output: -v (verbose – file name), -h (highlight – file name) (hash) Preconditions: –nodeps, –replacefiles, and –force (WARNING: BE CAREFUL HERE!) are options.Relocating with the following options: –excludepath, –prefix, –relocate, –badreloc, –root URL Support: ftp, http, etc.Examples: rpm -ivh binutils-220.127.116.11.8-12.i386.rpm rpm -Uvh finger-0.17-9-i386.rpm rpm -Fvh ftp:/updates.redhat.com/current/i386/*.rpm rpm -e diffutils-18.104.22.168.8-12.i386.rpm rpm -Uvh finger-0.17-9 rpm -e kernel-enterprise-2.4.9-e.12 rpm -e kernel-enterprise-2.4.9-e.12 The ″-U″ option should never, ever be used to install a new kernel RPM.
Here’s why: The ″-U″ update function attempts to install the new RPM by first removing the existing RPM from the system and then attempting to install the current RPM.Any issue that prevents the fresh RPM from being installed will result in the system being unbootable.This is not what you want, thus when installing a kernel RPM, always use the ″-i″ flag instead.
Queries (Packages and/or Information)
Installation with the command Rpm —i installation with the command Rpm —i installation with the command Rpm —i installation with the command (install new RPM; error if already installed) upgradable with the rpm -U switch (delete existing RPM, if any; install new) revs per minute -Freshness (update RPM only if package already installed) Erase all data from the hard drive with rpm -e (remove, delete, expunge) Alternatives that are widely available Output: Optional parameters: -v (verbose – file name), and -h (highlight) (hash) Preconditions: • nodeps, • replacefiles, • force (WARNING: THIS IS A HIGHLY RISKY CONDITION!Excluding paths and prefixes from the relocation process, including –relocate, –badreloc and –root.File Transfer Protocol (FTP) Supported URLs: Some examples are: rpm -ivh binutils-22.214.171.124.8-12.i386.rpm rpm -Uvh finger-0.17-9-i386.rpm rpm -Fvh ftp:/updates.redhat.com/current/i386/*.rpm rpm -e diffutils rpm -ivh binutils-126.96.36.199.8-12.i386.r rpm -e kernel-enterprise-2.4.9-e.12 is a command that installs the kernel enterprise 2.4.9-e.12 package.
The ″-U″ option should never be used to install a new kernel RPM.Here’s an example: First, the ″-U″ update function attempts to uninstall all previous versions of RPMs from the system before attempting to install a new RPM.Any issue that prevents the new RPM from being installed may result in the system being unable to start up properly..The ″-i″ flag should always be used when installing a kernel RPM to avoid this situation.
Queries – Verification (Files)
The RPM database provides a plethora of information about each and every file that is installed using an RPM.You may compare the current state of the file to the information cataloged by RPM when the package was installed to see whether there has been any change.rpm -V package name rpm -Va package name (verify all) rpm -Vf rpm (filename) rpm -Vp rpm -Vp rpm -Vp (package filename) Please keep in mind that many Linux distributions include a ″prelink″ RPM that attempts to reduce the amount of time required to start an application that uses a shared library (most applications use at least one shared library, and potentially dozens) by inserting special information directly into the program file of the application.
Although include this information helps programs start more quickly, the modifications to the files invalidate most of the file properties in the RPM database, including the latest file modification date, file size, and the MD5 checksum of the file in question.
Queries – Verification (Packages)
Rpm -import /mnt/cdrom/RPM-GPG-KEY rpm -q gpg-pubkey rpm -checksig m4-1.4.1-11.i386.rpm rpm -import /mnt/cdrom/RPM-GPG-KEY rpm -checksig m4-1.4.1-11.i386.rpm Examples: rpm -qf /path/filename /path/filename (what package owns filename) rpm -qf /path/filename -i /path/filename (what does it do) rpm -qp m4-1.4.1-11.i386.rpm -l m4-1.4.1-11.i386.rpm (files in m4) require m4-1.4.1-11.i386.rpm -qp m4-1.4.1-11.i386.rpm (prereqs needed to install m4) Glibc.so is provided by rpm -q -whatprovides glibc.so (what package provides requisite library)
Repair the RPM database
The RPM tool stores its information in its own unique database system, which was developed specifically for this purpose.It is possible for that database to get damaged; symptoms include assertions that an installed RPM package is missing, as well as attempts to update an RPM becoming unresponsive.The following instructions can be used to attempt to fix an RPM database that has been stalled or corrupt.
There is no assurance that this procedure will be successful.These steps can only be completed if you are signed in as a superuser (also known as ″root″).A root terminal window can be opened by copying and pasting the instructions from the command line.1.
Check to see that there are no RPM processes still operating on your computer.In order to identify them, use the ps command.Kill any ″rpm″ processes that you come across with the kill command; a ″kill -9″ may be required in some cases.2.Destroy the lock files that RPM makes use of.Db* can be removed with the rm -f command.
3) Rerun the ″rpm″ command if you were encountering problems with it hanging.If it works, you’re done for the day.If this is not the case, repeat Steps 1 and 2.Then you may move on to the next stage.4.
Create a backup of your RPM database using the following command: cd /var/lib mkdir rpm-backup sync./rpm/../rpm-backup rsync -av./rpm/.rpm -vv -rebuilddb 2>&1 >/tmp/rpmrebuilddb.log 5>&1 Rebuild your RPM database by using the following command: 6.Re-run the RPM command that failed.
Uses of RPM
- RPM may be used to do the following tasks: install packaged software
- upgrade packaged software
- delete package software
- query comprehensive information about installed packaged software
- validate the integrity of packaged software and the resultant software installation
The utility only works with packages that have been generated specifically for processing by the rpm package and have the a.rpm extension. (Please keep in mind that the use of RPM to create software is outside the scope of this tutorial.
The following is the basic format of a rpm command: rpm -option
|-i||install a package|
|-v||tells the rpm command to print out verbose (detailed) information as the command runs.|
|-U||upgrade a package|
|-qa||query all installed packages|
|-qa -last||all recently installed packages|
|-e||remove a package|
|-nodeps||install, upgrade or remove a package without checking for dependencies|
|-h||Print 50 hash marks as the package archive is unpacked – hash marks get printed out to assure the installer that the RPM is working, and if it is, how far along it is.|
|-test||tells the rpm command to test the installation or upgrade process but not to install the file|
|-Vp||verify a package|
The options can be combined in a way that looks like -ivh.

- it performs pre-installation tasks
- it uncompresses and places the files in the appropriate locations
- and it updates both the RPM database and the RPM file system.
RPM packages frequently have dependencies on other RPM packages.This indicates that the installation of one package is contingent on the existence of another package.You may check for package dependencies before installing them by executing the following command: prior to installing a package, execute the following command: rpm -i -test php55-5.5.10-1.el6.x86 64.rpm php55-5.5.10-1.el6.x86 64.rpm This is an example of a dependency that has failed:

- 3rd method (method 1): Installing an RPM package
- Method 2 of 3: Uninstall an RPM package
- Method 3 of 3: Configure installation parameters
Rpm (Redhat Package Manager) is a software package manager that is used by several GNU/Linux distributions to add, delete, and replace software packages.You, like many other Linux users, will at some point desire to change the apps that are installed on your system.Once you realize the depth of its capabilities and how to control it, the command rpm will quickly become your closest friend.
Method 1 of 3: Install an RPM package
- Download the RPM package of your choosing from the Internet. There are a plethora of package repositories available on the Internet, but if you’re looking for Red Hat-specific ones, you can obtain them from the following sources: your Red Hat Enterprise Linux installation media, which contains a large number of packages to install
- your Red Hat Enterprise Linux distribution’s package repository
- your distribution’s package repository
- your distribution’s package repository
- your distribution’s package repository
- your distribution’s package repository
- your distribution’s package repository
- your distribution’s package repository
- It contains the addresses of the original RPM repositories that are known to the YUM package management.
- Extra Software for Enterprise Linux (EPEL) is a Red Hat Enterprise Linux supplemental package repository that contains high-quality extra packages.
- Install the RPM package of your choice after downloading it. You have two options for installing it once it has been downloaded. To do a graphical installation, double click on the name of the downloaded package to open a window that will assist you through the installation process.
- In order to ″get your hands dirty″ and do a ″pro″ installation from the command line, you must first open a terminal by hitting the Ctrl+Alt+T keys on your keyboard at the same time. In order to complete the installation, you must manually type the command rpm -i package name and location in the terminal.
Method 2 of 3: Remove an RPM package
Open a command prompt window. The rpm -e package name command is used to remove a package. It will no longer be essential to accompany the name of the package with the extension of the package. If you wish to uninstall the text editor gedit from your system, you will need to type the command rpm -e gedit when the command prompt of your terminal appears on your screen.
Method 3 of 3: Add installation options
- Select the choices that will be applied to the installation. Choose the choices you wish to apply to the installation of your package from the drop-down menu that appears below. These options will be manifested in the form of flags, which you will attach to your vehicle following the instructions. If required, you can consolidate many orders into a single transaction. Make sure to include your settings in the install command. The following options are available for the installation of RPM packages: the suffix -h (or -hash) displays the progress of the installation as a bar composed of a series of letters beginning with the letter ″ ″ (hash)
- Testing should be limited to package installation tests only.
- -percent: displays the progress of the installation as a percentage of the total installation time
- Excludedocs: do not install documentation
- includeddocs: do not install documentation
- -replacepkgs: replace an existing package with a new copy of itself
- and more options
- -replacefiles: replace files belonging to another package with those belonging to this package
- -strength: disregard package and dependent file conflicts
- Prefix path>: relocate package to path> if possible
- -ignoresearch: ignore the package’s architecture
- -ignoreos: ignore the package’s operating system
- -nodeps: don’t check for dependencies
- -ftpproxy host>: use host> as an FTP proxy
- -ftpport port>: use port> as an FTP port
- -nodeps: do not check for dependencies
- Options that are often relevant include: —v: show further information
- VV: display debug information
- -root path>: specify an alternate root folder to be used instead of path>
- -rcfile rcfile>: specify an alternative RPM configuration to be used instead of rcfile>
- -dbpath path>: specify a path to be used to locate the RPM database
- It will be unusual that you will need to force an installation. If you really must, you can use the -force parameter with the rpm command. It is important to note that this will only function from the command line.
- Installing an RPM package using the -U (update) flag rather than the -i (install) flag guarantees that the most recent version of the RPM package is downloaded and installed. By typing man-rpm in a terminal, you will be able to learn about all of the choices available for the order rpm
- certain packages will require ″dependencies″ in order to function properly. In order for the package in question to function properly, you must install one or many extra packages in addition to the one you are interested in. To give you an idea of what I’m talking about, Ogle is a free DVD player. Ogle will not be able to play a DVD on its own, and it will require the installation of a few libraries in addition to its primary package in order to be able to meet your needs. If the RPM requires dependencies and you do not wish to fulfill them, you should consider using the nodeps option.
