Configure inheritance with default access control lists
- [Instructor] Standard Linux permissions only have one type of inheritance in the form of the SGID bit on directories. In that case, the files and directories created inside inherit the group owner of the parent directory, which there can only be one of. ACLs go much further as they let files and directories inherit any number of user or group permissions. These ACLs are called default ACLs. Keep in mind that if you want to allow a user to access a directory, you set a regular ACL on it first. If however, you want that user to access all new files and directories inside it, then set a default ACL. Usually, you'll need to do both of these operations. For this exercise, we'll make a directory called ACL dir. In a terminal, type in sudo mkdir /home/acldir and hit Enter. Type in your password and hit Enter again. If you already have this directory from another lesson, go ahead and use it. Now let's change into using cd. Type in cd /home/acldir and hit Enter. You can verify your pass by…
