• Create another plain-text file in that directory:

        $ touch /tmp/explain-write/gamma
        $ ls -l /tmp/explain-write/gamma
        -rw-r--r--  1 jkeenan  wheel  0 Jul 17 21:21 /tmp/explain-write/gamma

• Change directory permissions to prevent anyone other than root from writing

        $ sudo chmod 0755 /tmp/explain-write/
