Script previo antes de instalar Oracle en Fedora

Antes de instalar Oracle tenemos que hacer un montón de pasos en Linux y cualquiera se los aprende. Bien, pues me encontré en un  foro un script muy bueno que he modificado un par de cosas para adaptarlo a hoy:
#!/bin/sh
# Made by "Unlimited_Eng@hotmail.com"
# for techincal feedback please contanct me at this mail ""AhmedShabana2000@gmail.com""
# it is under GPL

# WIDE SCRIBT PARAMETER "EXIT STATUS"
E_NOTROOT=11 # you are not a root
E_NPAC_SOURCE=12 # you have no valid package source
E_INIT_BEFORE=13 # this scribt runs in this system before

# " " " "VARIABLES"
YUM_REPO_SERVER="" # may be added in the future %%%%

# FUNCTION INCLUSION
