If I have an RPM located on a local disk -
what is the diffrefence between the following yum commands?
sudo yum install /tmp/rpm_name.rpm
sudo yum localinstall /tmp/rpm_name.rpm
Note:
I use RedHat/CentOS 7.
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.

1In RHEL 6 and 7, what's the difference, if it wasn't simply an alias until 8? Is it that
localinstallonly accepts paths until 8? – Lightness Races in Orbit Nov 20 '18 at 10:27 -
@LightnessRacesinOrbit Right,
localinstallwas the old code and only accepts local paths through RHEL 7. In 8, the old code is gone andlocalinstallis simplyinstall. – 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
