Setting Environment variable from value in file
I've searched Google and now this forum. Best guess is my search fu is not good (and it probably isn't). The Google search did bring me here.

Background
I have a number of Korn Shell scripts who all use one of 3 values for an environment variable used in the backup system.
On occasion one or more value will be changed by the backup team.

This make me have to manually edit each script to change the value.


What I'd like to do is have 3 files. Each containing one value.

And have the value brought into the script and exported as the value for the specific environment variable.

Thanks
WolfBrother

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
