To set ACL correctly, you can use the fs user command.
Let’s take an example to set the ACL:
$ fs setacl path/until/directory name command
If we want to see ACL list, let’s execute this with the la (for l ist a cl):
$ fs la path/until/directory
To remove all the ACL rights for the user system:anyuser we have to write it (sa for s eta cl):
$ fs sa directory system:anyuser none
