that was my first thought too....

if I see admins asking about how to do 777 or 666 I assume that they are asking the wrong question.

what is the problem you are trying to solve?
why do you think you need 777 ?

umask(2)							System Calls Manual							  umask(2)

NAME

       umask - Sets and gets the value of the file creation mask

SYNOPSIS

       #include <sys/types.h>

       #include <sys/stat.h>

       mode_t umask (	   mode_t cmask );

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       umask():  POSIX.1, XPG4, XPG4-UNIX

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS

       Specifies the value of the file mode creation mask.

DESCRIPTION

       The  umask() function sets the file mode creation mask of the process to the value of the cmask parameter and returns the previous value of
       the mask.  The cmask parameter is constructed by logically ORing file permission bits defined in the sys/mode.h header file.

       Whenever a file is created (by the open(), mkdir(), or mknod() function), all file permission bits set in the file mode creation  mask  are
       cleared in the mode of the created file. This clearing lets users restrict the default access to their files.

       The mask is inherited by child processes.

RETURN VALUES

       Upon successful completion, the previous value of the file mode creation mask is returned.
