Q:

RHEL 7 security patch installation from tar

Novice Linux guy here

I have a huge (5G) linux-security-patches tar. Upon extracting, I see its got loads of rpms. What is the most efficient way to install them all ? Also, is it same as installing each rpm individually ?

A:

RPMs should be with rpm or yum. If there is no some kind of install script within the tar file, the simplest (and cleanest) way to install all of them in one go with yum:
yum localinstall *.rpm
