Installing Applications Under Linux RedHat

Installing applications under Linux has been a major stumbling block for Linux newbies ,

even though the situation has improved with automatic installers (Like

yum,aptitude,autopackage etc) still applications installation under Linux is tricky.

Installing rpm packages on Redhat,Fedora Based Systems:

For Redhat based systems rpm is the standard format for packages,

it stands for RedHat

Package Manager. The files have ".rpm" extensions. The rpm format's major advantage is it

is easier to maintain applications installed using rpm than compiling from different sources.

Also various dependencies for applications are previously determined before installing the

applications which ensures error free running of application after installing the application.

To install an rpm package use command:

rpm -ivh PackageName

TO uninstall rpm package use :

rpm -e PackageName

PackageName is different from filename You used to install the package . This is actually the

name of software that is installed.

If you have some file on your system and you don’t recognize to which package it belongs

use the command : -

rpm -qf filename with path

this will return the name of package the file belongs to.

If you want to know what files and where the rpm installs for a specific package use the

following command : -

rpm -qpl packagename

If you want to upgrade an existing package on your system use :-

rpm -Uvh packagename

this command uninstalls the old version of the package and installs the new version of the

package. This commands works even when there are no existing version of application

installed hence this can be effectively used for Installing new packages.
