Creating Flexible Permissions Hierarchies

[pfeingerhein]

When Unix mode-based permissions just aren't enough, what can I do ?

[homer]

You should use ACLs(Access control lists), are a feature that is relatively new to the Linux operating system, but has been available in FreeBSD and Solaris for some time. While ACLs do not inherently add "more security" to a system, they do reduce the complexity of managing permissions. ACLs provide new ways to apply file and directory permissions without resorting to the creation of unnecessary groups.

How can I modify or remove ACLs ?

[homer]

Use the setfacl command. To modify an ACL, the -m option is used, followed by an ACL specification and a filename or list of filenames. You can delete an ACL by using the -x option and specifying an ACL or list of ACLs.
