face(1) 							   User Commands							   face(1)

NAME

       face - executable for the Framed Access Command Environment Interface

SYNOPSIS

       face [-i init_file] [-c command_file] [-a alias_file] [filename...]

DESCRIPTION

       The  Framed  Access  Command  Environment Interface (FACE) presents your files and file folders on the screen through a system of menus and
       forms if you are properly set up as a FACE user.

       filename must follow the naming convention Menu.xxx for a menu, Form.xxx for a form, and Text.xxx for a text file, where xxx is any  string
       that  conforms  to  the	UNIX   system  file  naming conventions. The Form and Menu Language Interpreter (FMLI) descriptor lifetime will be
       ignored for all frames opened by argument to face. These frames have a lifetime of immortal by default. If filename is not specified on the
       command line, the  FACE Menu will be opened along with those objects specified by the
	LOGINWIN environment variables. These variables are found in the user's .environ file.

OPTIONS

       The following options are supported:

       -a alias_file	       Alias file

       -c command_file	       Command file

       -i init_file	       Initial file

OPERANDS

       The following operand is supported:

       filename        The full pathname of the file describing the object to be opened initially.

EXIT STATUS

       The face command will return a non-zero exit value if the user is not properly set up as a  FACE user.

FILES

       $HOME/pref/.environ

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:
