  The above diagram shows the sensitive directories, into

  which most of the users should not be allowed to write!

 Type the command that will make all of the files in the /bin

 directory executable by all, but readable and writable only by 

 the owner.  Use octal notation to specify the absolute form of 

 the command.

 $PROMPT$

 That is correct!

 You've got it on the 2nd try.

 Please use chmod with permission 711 for all files in /bin

 Please type chmod 711 /bin/*

 $PROMPT$

FORGET2

 Observe the result on the terminal!

 chmod 711 /bin/*
