SU issues

Hi,
I have automated a build process that does the following activities.
1. check out code from cvs to a specific directory
2. build the revision checked out with 'ANT'
3. integrate the compiled code with the QA/UAT or new environment
(/apps/QA or /apps/UAT or /apps/new directory)

I have separated this into two scripts. The first one does steps 1 and 2 and then calls number 3. The reason that they are separated is that based on permissions steps 1 and 2 can be done only by and individual id while step 3 has to be done by the build user account that owns the integrated environments.

Here is the problem. I made the process interactive using 'select' contructs to allow the user to select different options. After steps 1 and 2 are completed I am executing and 'su' to switch to the build id to integrate the compiled code. However there are options in the second script also. For some reason when I 'su' the shell goes into an infinite loop when I prompt the user for feedback in the second script. It doesn't wait for response. I this the behavior of 'SU'? Is there any way around this? Thank you.

Here's how I su over in the script:

Code:

su - $vBuildUser <<-EOF
eval "$unixBuild -s $vSystem -r $vRevision -e $vIntegratedEnvironment"
wait
EOF
exit
exit

cvs-debuild

CVS-DEBUILD(1)                                                General Commands Manual                                               CVS-DEBUILD(1)

NAME

       cvs-debuild - build a Debian package using cvs-buildpackage and debuild

SYNOPSIS

       cvs-debuild [debuild options] [cvs-buildpackage options] [--lintian-opts lintian options]

DESCRIPTION

       cvs-debuild  is  a  wrapper  around cvs-buildpackage to run it with debuild as the package-building program.  (This cannot simply be accom-
       plished using the -C option of cvs-buildpackage, as it does not know how to handle all of the special debuild options.)

       The program simply stashes the debuild and lintian options, and passes them to debuild when it is called by cvs-buildpackage.  All  of  the
       standard debuild options may be used (as listed below), but note that the root command specified by any --rootcmd or -r command-line option
       will be passed as an option to cvs-buildpackage.  The first non-debuild option detected will  signal  the  start  of  the  cvs-buildpackage
       options.

       The  selection  of  the  root  command is slightly subtle: if there are any command-line options, these will be used.  If not, then if cvs-
       buildpackage is set up to use a default root command, that will be used.  Finally, if neither of these are the case, then debuild will  use
       its procedures to determine an appropriate command, as described in its documentation.

       See the manpages for debuild(1) and cvs-buildpackage for more information about the behaviour of each.

OPTIONS

       The  following are the debuild options recognised by cvs-debuild.  All cvs-buildpackage and lintian options are simply passed to the appro-
       priate program.  For explanations of the meanings of these variables, see debuild(1).

       --no-conf, --noconf

       --rootcmd=gain-root-command, -rgain-root-command

       --preserve-env

       --preserve-envvar=var, -evar

       --set-envvar=var=value, -evar=value

       --lintian, --no-lintian

       --ignore-dirname, --check-dirname
              These should not be needed, but it is provided nevertheless.
