Install the RPM package
To install the rpm package, run the rpm command with the option "-i".
Sub-options commonly used with the "-i" option include the "-v" option, which displays the package name, and the "-h" option, which displays the progress of the installation in 50 hashes (#).
Note that this rpm does not necessarily require root privileges, but if there are processes in the installation process that require root privileges, an error will be displayed.
