The fixGpfsAcls command

This tool sets the ACLs of the files given on the command line to those they would inherit from theirparent directories. Directories given on the command line are left unchanged, but all their content is recursively scanned and the ACLs of all their sub-directories and files are set as if freshly inherited. More...

Detailed Description

This tool sets the ACLs of the files given on the command line to those they would inherit from theirparent directories. Directories given on the command line are left unchanged, but all their content is recursively scanned and the ACLs of all their sub-directories and files are set as if freshly inherited.
