Last updated on JUNE 17, 2021

Applies to:

Linux OS - Version Oracle Linux 4.4 and later
Oracle Cloud Infrastructure - Version N/A and later
Oracle Compute Cloud Service - Version N/A to N/A
Linux x86-64

Goal

How can I revert bulk permission changes after the root user unintentionally recursively modified permissions on the system with the chmod -R command?

Examples of this are:

chmod -R go-rw /


chmod -R 755 ./*

or any other recursive combination of permissions.
