Since /var/tamp always exists anyway, no need to create it. #cp /etc/fstab /var/tmp #chown :root /var/tmp/fstab #useradd mary #useradd alice #useradd -u 1000 bob #setfacl -m u:mary:rw-,u:alice:r-x,u:bob:rw-,o::r /var/tmp/fstab

Copy /etc/fstab document to /var/TMP directory. It says to copy to the /vat/TMP folder why are all the comments making changes to the /var/tmp/fstab directory?

fstab is not a directory, it is a file. so the file you'll modify and have now is the fstab under /var/tmp location
