write Permissions on a Directory: Example

• Directory owned by root but with wide-open permissions

        $ ls -ld /tmp/explain-write/
        drwxrwxrwx  2 root  wheel  512 Jul 17 21:08 explain-write/

• QUIZ: In that directory, can I create a plain-text file named beta?

        $ touch /tmp/explain-write/beta

• Yes, I can.

        $ ls -l /tmp/explain-write/
        total 0
        -rw-r--r--  1 jkeenan  wheel  0 Jul 17 21:09 beta

• And I can delete it as well.

        $ rm /tmp/explain-write/beta
        $ ls -l /tmp/explain-write/
        total 0
