In RHEL 5 and previous versions, yum install only accepted package names from enabled repositories, and did not accept paths to local RPMs; you had to use yum localinstall to install these.

In RHEL 6 and later, yum install accepts both package names and local filenames, so localinstall is no longer necesary, but it's included for backward compatibility.

In RHEL 8, dnf localinstall is simply an alias for dnf install.

    In RHEL 6 and 7, what's the difference, if it wasn't simply an alias until 8? Is it that localinstall only accepts paths until 8? – Lightness Races in Orbit Nov 20 '18 at 10:27
  • @LightnessRacesinOrbit Right, localinstall was the old code and only accepts local paths through RHEL 7. In 8, the old code is gone and localinstall is simply install. – Michael Hampton Nov 20 '18 at 13:07

Note that in CentOS7 there is a subtle difference

sudo yum install <alreadyExistingPackage>

will give an error Error: Nothing to do

but the

sudo yum localinstall <alreadyExistingPackage>

will not give an error

If you run your script with -e option

#!/bin/bash -e

you will notice this difference
