The toolkit was first launched by Red Hat and later borrowed by other Linux developers. Because it saves a lot of time for Linux users, it is widely used to install and remove software under Linux.
Here is a description of its specific use of the method.
[Root@ford/root] # Rpm-qa | More1.
We have a new software, before the installation, generally have to look at the contents of the package, assuming that this file is: linux-1.4-6.i368.rpm, we can use this command to view:
Rpm-qpi linux-1.4-6.i368.rpm
Details of the package will be listed, including how many files, file names, file sizes, creation time, compile date, and so on.
2. All of the files listed above are not necessarily installed when installed, just as the installation of a program in Windows is typical, complete, and customized, Linux will also allow you to choose the installation method, at this time we can use the following command to see what the package will be installed in the system, to facilitate our choice:
RPM-QPL LINUX-1.4-6.I368.RPM3.
After selecting the installation method, start the installation. We can use
RPM-IVH linux-1.4-6.i368.rpm
command to install the software. During the installation process, if you are prompted to install the software or for other reasons, but if we do want to execute the installation command, we can add a parameter "-replacepkgs" after-IVH:
rpm-ivh-replacepkgs LINUX-1.4-6.I368.RPM4.
Sometimes we uninstall one of the installed software, just perform
RPM-E the filename > command. Upgrading to a lower version of the software is a good way to improve its functionality, which eliminates the hassle of installing new software after uninstalling, and to upgrade a software, you only need to execute the following command:
RPM-UVH file name >
, note: This time the filename must be upgraded to upgrade the software patch 6. Another way to install the software is a unique Linux, but also a powerful feature of RMP: through the FTP site directly online installation software. When you find the site that contains the software you need and connect to the site, execute the following command to install online, such as installing linux-1.4-6.i368.rpm online, and using the command:
Rpm-i linux/redhat/...-1.4-6.i368.rpm7.>ftp://ftp.pht.com/pub/linux/redhat/...-1.4-6.i368.rpm
In our use of the computer process, will inevitably be wrong operation, if we mistakenly deleted a few files and affect the performance of the system, how to find out what is missing files? The RPM package provides a feature to find corrupted files, executing this command:
Rpm-va
, Linux will list all the corrupted files for you. You can fix it with a Linux installation CD. Linux system in a wide range of files, in the use of the process, will inevitably encounter the files we do not know, in Windows we can use the "Start/Find" menu to quickly determine which folder a file belongs to, in Linux, the following command line can help us quickly determine which package a file belongs to:
RPM-QF file name >
When each package is installed in the Linux system, the installation files will be in the RPM database "check-in", so we want to query the properties of an installed software, just go to this database to find it. Note: The query command at this time is different from some of the queries described just now, this method only applies to installed packages! Command format: First, install command format:
Rpm-i (or--install) options file1.rpm ... filen.rpm
Parameters: file1.rpm ... filen.rpm the file name details of the RPM package that will be installed:
