The file is a member of the root group and belongs to root. So root(rw) have rw_r_ _ r _ _ It is not executable by anyone. natasha has read and write access. harry has no read or write access. All other users can read the file. cp /etc/fstab /var/tmp/fstab chown root:root /var/tmp/fstab (not requireed) chmod 644 /var/tmp/fstab(rw_r _ _r_ _) setfacl -m u:natasha:rw /var/tmp/fstab setfacl -m u:harry:--- /var/tmp/fstab getfacl /var/tmp/fstab

can not be executed by any user... execute is 1 so 1 is taken from every ugo natasha can read and write ...setfacl -m u:user:rw- /var/tmp/fstab harry cannot read and write ...setacl -m u:user:--- /var/tmp/fstab all other users can write (444)... I dont think this means other as in users,groups,others so setfacl 000 for harry ... if they can write they can read so 666??? idk
