Solaris request script

Hi,

In the request script I need to read user input and store to variable to use it later in postinstall script.

e.g.

Code:

LOGDIR=/app/log

    echo "Please type the Log Directory : (current value: $LOGDIR)"
    read LOGDIR

When asked, if the user enters a value the parameter is ok and I can use it later, but if the user presses enter then the LOGDIR value is set to "" and doesn't keep it's initial value.

In Linux I use a function

Code:

readDefault()
{
    ARGS=""
    N=1
    LOCALBUF=""
    until  [ $N -eq $# ]
    do
        eval ARG=\${$N}
        ARGS=" $ARGS $ARG"
        N=`expr $N + 1`
    done
    read $ARGS LOCALBUF
    if [ -n "$LOCALBUF" ]
    then
        VARNAME=${!#}
        export $VARNAME=$LOCALBUF
    else
        echo "Using current value."
    fi
}

But in the Solaris request script I get " bad substitution" at line readDefault LOGDIR

Thanks,
Bianca

NAME

       se_dpkg,se_apt-get,se_aptitude,se_dpkg-reconfigure,se_dselect,se_synaptic  -  run  a  Debian package system programs in the proper security
       context

SYNOPSIS

       se_dpkg [  <<dpkg ARGS>> ... ]
       se_apt-get [ <<apt-get ARGS>> ... ]
       se_aptitude [ <<aptitude ARGS>> ... ]
       se_dpkg-reconfigure [ <<dpkg-reconfigure ARGS>> ... ]
       se_dselect [ <<dselect ARGS>> ... ]
       se_synaptic [ <<synaptic ARGS>> ... ]

DESCRIPTION

       These programs are all symbolic links to a simple wrapper script that uses run_init to run actually run	the  corresponding  program  after
       setting up the proper context.  run_init acquires a new Psuedo terminal, forks a child process that binds to the pseudo terminal, forks the
       program (dpkg,apt-get,aptitude,synaptic,dselect,ordpkg-reconfigure) that the user actually needs to run, and then sits around and  connects
       the  physical  terminal it was invoked upon with the psuedo terminal, passing keyboard into to the child process, and passing the output of
       the child process to the physical terminal.

       It sets up the psuedo terminal properly based on the physical terminal attributes, and then sets the user's terminal to	RAW  mode,  taking
       care to reset it on exit.
