NOTE:: ``setfacl`` with ``-x`` key can't remove specific permission (like read/write/executable bit), you should remove corresponding user or group and set new or explicitly specify desired permission for user or group with ``-m`` option.Remove all ACL permissions:: $ sudo setfacl -b ~/tmp/dirRemove default ACL:: $ sudo setfacl -k ~/tmp/dirBackup and restore ACL:: $ sudo getfacl ~/tmp/dir >~/tmp/backup.acl $ sudo setfacl --restore=~/tmp/backup.aclAdd default ACL to directory to make ACL permission inheritance:: $ sudo setfacl -d -m u:nobody:rwx /srv/www $ sudo setfacl -m u:nobody:rwx /srv/wwwor by single command:: $ sudo setfacl -m u:nobody:rwx,d:u:nobody:rwx /srv/wwwTo apply permission recursively add ``-R`` option:: $ sudo setfacl -R -d -m u:nobody:rwx /srv/www $ sudo setfacl -R -m u:nobody:rwx /srv/www.. NOTE:: default ACL is set only on directories and is applied only to directory children. So you should explicitly add permission to directory itself!
