What Is The RPM?
Hello,
Do you know what is the RPM?
RPM is the RPM Package Manager. It is an open packaging system available for anyone to use. It allows users to take source code for new software and package it into source and binary form such that binaries can be easily installed and tracked and source can be rebuilt easily. It also maintains a database of all packages and their files that can be used for verifying packages and querying for information about files and/or packages.
Red Hat, Inc. encourages other distribution vendors to take the time to look at RPM and use it for their own distributions. RPM is quite flexible and easy to use, though it provides the base for a very extensive system. It is also completely open and available, though we would appreciate bug reports and fixes. Permission is granted to use and distribute RPM royalty free under the GPL.
RPM is an open packaging system that is available for anyone to use. It works on all Linux as well as currently on various other UNIX flavours: IRIX, Solaris, SunOS, AIX, HP/UX, AmigaOS, and FreeBSD.
Installing Packages
RPM packages typically have file names rpm -i prashant-1.1-1.i386.rpm which includes :-
package name prashant
version 1.1
release 1
architecture i386
How to install RPM?
rpm -ivh prashant-1.1-1.i386.rpm
uninstalling packages
rpm -e prashant-1.1-1.i386.rpm
Upgrading Packages
rpm -Uvh prashant-2.0.i386.rpm
Verifying Packages
rpm -v prashant
bingo

RPMKEYS(8) System Manager's Manual RPMKEYS(8) NAME
rpmkeys - RPM Keyring SYNOPSIS
rpmkeys {--import|--checksig} DESCRIPTION
The general forms of rpm digital signature commands are rpmkeys --import PUBKEY ... rpmkeys {-K|--checksig} PACKAGE_FILE ... The --checksig option checks all the digests and signatures contained in PACKAGE_FILE to ensure the integrity and origin of the package. Note that signatures are now verified whenever a package is read, and --checksig is useful to verify all of the digests and signatures associated with a package. Digital signatures cannot be verified without a public key. An ASCII armored public key can be added to the rpm database using --import. An imported public key is carried in a header, and key ring management is performed exactly like package management. For example, all cur- rently imported public keys can be displayed by: rpm -qa gpg-pubkey* Details about a specific public key, when imported, can be displayed by querying. Here's information about the Red Hat GPG/DSA key: rpm -qi gpg-pubkey-db42a60e Finally, public keys can be erased after importing just like packages. Here's how to remove the Red Hat GPG/DSA key rpm -e gpg-pubkey-db42a60e SEE ALSO
popt(3), rpm(8), rpmdb(8), rpmsign(8), rpm2cpio(8), rpmbuild(8), rpmspec(8), rpmkeys --help - as rpm supports customizing the options via popt aliases it's impossible to guarantee that what's described in the manual matches what's available. http://www.rpm.org/ <URL:http://www.rpm.org/> AUTHORS
