looking for a simple way to organize envs on our unix box...

Manuel Contreras — Mon, 25 Aug 2008 15:27:59 GMT

would like to standardize how we set envs on our unix box, so I thought a menu would be a great way to accomplish this.

The problem I'm experiencing, is the value is set...but ONLY during the time the menu is initiated.

please see below:
> /home/is/bin/r12MENU.sh
**================================================================**
** to Set your environment, select one of the following: **
** 1.) DEVSID - Development Environments **
** 2.) UATSID - CRP2/UAT Environments **
** 3.) GLDSID - GOLD Environments **
** 4.) APPSSID - PROD Environments **
** e.) EXIT this menu **
**================================================================**

** Enter your response (1, 2, 3, 4 or [e]): 1

**=========================================================**
** You have chosen DEVSID - Development Environments **
** **
** your environment will now be set... **
**=========================================================**
devsid

the devsid you see above is an ECHO within the menu script on oracle_sid.
so I know it's setting the correct env, but only during the running of the menu-script.

If I perform an echo from command line...it's set to whatever was defined before running the menu.

If I run the individual scripts from CL, it sets my env correctly...so it's not the individual env scripts.

any assistance would be appreciated,

"If I run the individual scripts from CL, it sets my env correctly...so it's not the individual env scripts." Doubtful. How are you "running" them?

As for the remainder of the problem:

that is the normal behaviour...you are altering the ENV of the child process, so the changes "disappear" when the child ends.

you need to "dot-in" (source) both the menu script AND the scripts run by the menu to change the environment.

ie:
. /home/is/bin/r12MENU.sh

and within r12MENU.sh each selected item must be "sourced" as well

Alternatively, one *might*, for each "selection":
a) Set environment
b) execute a "new" shell. Puts you in a sub-shell with the "correct" environment
c) exit the sub-shell, which should return you to the menu script.

Can't vouch for the later, as I've not tried it.

Shalom,

1) Figure out what is common to all environments.

2) Rather than have a menu required for login which can mess up the users if they want to automate some of their work, have a little script that pops up. User types myenv. Then the menu comes up and sources one of the 4 environment files. Set up a default or set a single variable for each user with the best guess for what they do. if [ "$USENV" == "dev" ] then . devenv

Something like that.

referencing the menus and env scripts with ". menu.sh" worked like a charm.

cross this one off the list :)

thanks guys
