What is ACL Ubuntu? An ACL consists of entries specifying access permissions on an associated object. ACLs can be configured per user, per group or via the effective rights mask. These permissions apply to an individual user or a group, and use the same as rwx found in regular permissions.
Does Linux have ACL? Viewing the current ACL
This type of situation is what Linux Access Control Lists (ACLs) were intended to resolve. ACLs allow us to apply a more specific set of permissions to a file or directory without (necessarily) changing the base ownership and permissions. They let us “tack on” access for other users or groups.
Where is ACL on Linux? Use the ‘getfacl’ command for viewing ACL on any file or directory. For example, to view ACL on ‘/tecmint1/example’ use below command.
How do I know if my ACL is enabled Linux?
- Check current kernel version and filesystem: uname -r. df -T or mount | grep root.
- Look for existing ACL settings (the “usual” config place is on /boot): sudo mount | grep -i acl #optionnal. cat /boot/config* | grep _ACL.
