Unix Environment Script
Hi,
I was wondering what is the best way to write a centralized unix environment script. This script would set the application environment variables per specific environment. e.g. dev, qa, test or prod.
We currenlty have 2 types of env files e.g. .envfile and set.env per environment. These contain all the necessary application variables that need to be set. And these are set through the calling script via . .envfile or . set.env (we dot the file to set/export the variables.) We would like to consolidate these env files.
How could we accomplish to have only one env shell script to set 4 different environemnts? I guess this need to be based on "host" and/or "user" per environment.
I would appreciate your thoughts on this topic.
Thanks in advance,
AC

service(8) System Manager's Manual service(8)
NAME
service - run a System V init script
SYNOPSIS
service SCRIPT COMMAND [OPTIONS]
service --status-all
service --help | -h | --version
DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working
directory set to /.
The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the
invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and
stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start
command.
service --status-all runs all init scripts, in alphabetical order, with the status command.
EXIT CODES
service calls the init script and returns the status returned by it.
FILES
/etc/init.d
The directory containing System V init scripts.
ENVIRONMENT
LANG, TERM
The only environment variables passed to the init scripts.
SEE ALSO
/etc/init.d/skeleton,
update-rc.d(8),
init(8),
invoke-rc.d(8).
