 Let us use the command ls -l again, but this

 time we'll focus on the file protection.

 At the prompt please enter the appropriate command to see 

 the detailed listing for the files A, B and C.

  Let us focus on the owner's permissions.

 crwx------   2 admin  root     192 Apr 16 09:07 A

 drwxr-xr-x   1 root   root   11800 Apr 16 10:43 B

 -rw-rw-r--   1 yori    cti    5212 Apr 16 11:33 C

  Note that the owner has READ, WRITE and EXECUTE

  permissions for the files A and B, and

  READ and WRITE permission for the file C.

  Let us focus next on the group permissions.

 crwx------   2 admin  root     192 Apr 16 09:07 A

 drwxr-xr-x   1 root   root   11800 Apr 16 10:43 B

 -rw-rw-r--   1 yori    cti    5212 Apr 16 11:33 C

  Note that the group has no privileges for the

  file A, READ and EXECUTE permission for the

  directory B, and READ and WRITE permission for 

  the file C.

  Finally, let us focus on the others' permissions.

 crwx------   2 admin  root     192 Apr 16 09:07 A

 drwxr-xr-x   1 root   root   11800 Apr 16 10:43 B

 -rw-rw-r--   1 yori    cti    5212 Apr 16 11:33 C

  Note that the others have no privileges for the

  file A, READ and EXECUTE permission for the directory B 

  (i.e. they can cd into the directory), and READ only 

  permission for the file C.
