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

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
