Configure the permissions of /var/tmp/fstab
Copy the file /etc/fstab to /var/tmp/fstab. Configure the permissions of /var/tmp/fstab so that: the file /var/tmp/fstab is owned by the root user. the file /var/tmp/fstab belongs to the group root. the file /var/tmp/fstab should not be executable by anyone. the user natasha is able to read and write /var/tmp/fstab. the user harry can neither write nor read /var/tmp/fstab. all other users (current or future) have the ability to read /var/tmp/fstab.

Suggested Answer: See explanation below.
cp -a /etc/fstab /var/tmp
cd /var/tmp
ls -l
getfacl /var/tmp/fstab
chmod ugo-x /var/tmp/fstab
[ No need to do this, there won't be execute permission for the file by default]
# setfacl -m u:natasha:rw /var/tmp/fstab # setfacl -m u:harry:0 /var/tmp/fstab(zero)
[Read permission will be there for all the users, by default. Check it using ls -l /var/tmp/fstab] Verify by
[ ls -la /var/tmp/fstab]
