su from root to anotehr user in script

Hi,

I am not able to print a variable.
I run this script as 'root'

Code:

#!/bin/ksh
#
su - orauser << !
. /opt/ora/env/ora-db.env
echo $ORACLE_HOME
!

I get this error

Code:

stty: : Not a typewriter

It's not printing $ORACLE_HOME.

I am able to print $ORACLE_HOME manually.

thanks

Sorry, did not work.

You could do something like this also:

Code:

su orauser -c "(. /opt/ora/env/ora-db.env ; echo $ORACLE_HOME ; )" -

( opens a subshell
{ runs it in the environment

man bash
man su

Actually sudo is made for what this, rather than su
