prefix
PREFIX(1) General Commands Manual PREFIX(1)NAME
prefix - Script that allows you to reconfigure environment variables for multiple installations of a set of software installed on the same
machine
SYNOPSIS
prefix
DESCRIPTION
It is assumed that the software for each installation is all under a single directory whose name is assigned to an environment variable
called PREFIX.
This arrangement of enabling multiple installations of software on a single machine is useful at many times. On a single server, it can
provide for development, test, and production installations of software. Alternatively, on development servers, it allows for multiple
development "sandboxes", one for each developer. On production servers, it allows for multiple versions of the production software to be
installed. One might be the currently running software, one the previous software kept online as a fall-back, and one a new release of
software wich is scheduled to be brought online soon.
There are three usages of the prefix script:
(1) The interactive usage should be placed as the last line
of a user's ".profile". The user must be running the
Korn shell (ksh) or the Bourne Again shell (bash).
The user is prompted to enter one of the known PREFIX locations,
specified in the $HOME/.prefixes file or the /etc/prefixes file.
During configuration, the $PREFIX/.prefixrc file is sourced
in order to accomplish environment-specific configurations.
(2) The non-interactive user configuration does not consult
$HOME/.prefixes or /etc/prefixes or prompt the user, but merely
configures the environment in accordance with the cmd line argument.
(3) The batch command usage is mainly for running commands from
cron or running commands in another environment without changing
to that environment.
Usage (1): . prefix (sets up environment)
(2): . prefix <prefix> (non-interactive setup)
(3): prefix <prefix> <cmd> <args> (runs cmd configured for PREFIX)
