Envy RmpO Shell independent environment-variable mgmt JPRIT
Envy is a shell-independent (sh/ksh/bash/zsh/csh/tcsh) solution for
environment-variable management:
1. Easily customizable profile/login scripts are included for booting
the environment upon login.
2. A mechanism is provided for setting environment-variables in a
variety of flexible ways.
3. Essential absolute paths are specified once. Everything else can
be relative.

MANPATH+=/usr/dt/man:/usr/openwin/man
LD_LIBRARY_PATH+=/usr/dt/lib:/usr/openwin/lib
OPENWINHOME=/usr/openwin
This means that when 'openwin' is loaded, two components are prepended
to the PATH, MANPATH, and LD_LIBRARY_PATH; and OPENWINHOME is set to
/usr/openwin. What makes envy unique is that YOU CAN ALSO UNLOAD
'openwin' to unprepend and unset each of the variables modified during
the load.
----------------------------------------------------------------------
* How does a typical install work?
First, edit envy_config.pm and install envy. Then you need to setup
the initial production & development (& test?) environments. $ETOP
needs to be set to the top of your production tree such that:
$ETOP/(bin|etc|include|lib|man|share|var)
You'll need an prod.env that looks like this:
ETOP=/nw/prod/usr
PATH+=/nw/prod/usr/bin
LD_LIBRARY_PATH+=/nw/prod/usr/lib
PERL5LIB+=/nw/prod/usr/lib/perl5
MANPATH+=/nw/prod/usr/man:/nw/prod/usr/lib/perl5/man
ENVY_PATH+=/nw/prod/usr/etc/envy
You can also create a dev.env file for development:
ETOP=/nw/dev/usr
PATH+=/nw/dev/usr/bin
LD_LIBRARY_PATH+=/nw/dev/usr/lib
PERL5LIB+=/nw/dev/usr/lib/perl5
MANPATH+=/nw/dev/usr/man:/nw/dev/usr/lib/perl5/man
ENVY_PATH+=/nw/dev/usr/etc/envy
Put both of these files in /nw/prod/usr/etc/envy/. To set up a
particular user for envy, all you have to do is replace $HOME/.profile
or $HOME/.login with symlinks:
ln -s /nw/prod/usr/etc/login/dot.profile $HOME/.profile
ln -s /nw/prod/usr/etc/login/dot.login $HOME/.login
Any old $HOME/dot files will be renamed if necessary (and not
deleted).
