Download and install an RPM file on fly from ftp or http server

Many books or free Linux tech support recommends downloading an RPM file using wget and installing it using rpm command. For example to install awstats rpm:

Go to /tmp directory
$ cd /tmp
Download awstats using wget
$ wget http://easynews.dl.sourceforge.net/sourceforge/awstats/awstats-6.5-1.noarch.rpm
Now install awstats
$ sudo rpm -ivh awstats*OR# rpm -ivh awstats*

To be frank you can skip all three steps with one command:
# rpm -ivh http://easynews.dl.sourceforge.net/sourceforge/awstats/awstats-6.5-1.noarch.rpmOutput:

RPM command is capable of downloading and installing an RPM file on fly. This is will save your time.

Please note that only use this method if you trust remote server/rpm file. Otherwise it will be a security nightmare for you.
