AANVANG

 The octal value for file protection may be computed from

 the numeric values shown in the table above. 

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

     owner: read, write and execute privileges                        

     group: read and execute privileges only                 

     other: no privileges 

the octal value for the mode would be: 750.
