 The octal value for file protection may be computed as shown above:

     owner   |   group   |   other

   -----------------------------------

  |  r  w  x  |  r  w  x  |  r  w  x  | 

  |  4        |  4        |  4        | 

  |    +2     |    +2     |    +2     |

  |       +1  |       +1  |       +1  |

   -----------------------------------

  |   digit   |   digit   |   digit   |

For example, if you want to set the following protections:

     the owner has read and write privileges

     the group has read privileges only, and

     other has no privileges (-), 

the octal value for the mode would be: 640!

 Which can also be represented as: rw-r-----!

 The command chmod - for changing file protection

 has the syntax:

         chmod  protection mode  filenames

 where protection mode is an octal value.  The command

 to give to all users all privileges to the file tmp, 

 would be:

 $PROMPT$

 That is correct!

 You've got it on the 2nd try.

 Good, you understand the concept.

 Please type chmod 777 tmp

 Please type chmod 777 tmp

 You will be helped this time.

 $PROMPT$

  Observe the result on the terminal!

 chmod 777 tmp
