An rpm package may be already installed and we may need to update or upgrade it. The
-U option is used to upgrade the already installed package. In the following example, we upgrade the
$ rpm -Uvh nmap.rpm
Install-Package without Dependencies
By default, a package may have some dependencies and these dependencies should be met during installation. The regular installation checks these dependencies and then completes the installation. But we can prevent this dependency check with the
$ rpm -ivh --nodeps nmap.rpm
The rpm command can be also used to remove or delete or erase an installed package. The
-e option is used for this operation. There is no need to provide an extra option for the removal of the package.
$ rpm -e nmap.rpm
Remove/Delete Package without Deleting Dependencies
By default, the package removal also removes or deletes all related dependencies. But we can prevent dependency removal with the
$ rpm -evh --nodeps nmap.rpm
We can query a package whether it is installed or not by using the
-q option. Also, the package name should be provided. If the package is installed the complete package name is displayed with the version information. In the following example, we query for the
$ rpm -q tmux
