Thread: Put fixed answers instead of promt for user input

I am trying to put answer bin in script
after line
${PRINTF_CMD} "Enter an administrative group ( ${GROUP} ): "

When running a complete script in terminal, it shows
"Enter an administrative group ( bin ): "
and prompts for user input.
I want to automate this script by putting my fixed answers in this script.

I have tried with below

Code:

command << EOF
bin
EOF

after line of ${PRINTF_CMD} "Enter an administrative group ( ${GROUP} ): "
but it doesnt work.

Please help!



PS. Complete part of script is (down):

Code:

set_group() 
{
    DEF_GROUP="`list_default_group`"
    if [ -z "${1}" ];then
        ${ECHO_CMD}
        ${ECHO_CMD} "This application is a suid root program, which allows the" 
        ${ECHO_CMD} "root user or members of the administrative group to have"
        ${ECHO_CMD} "administrative privileges. These privileges include adding,"
        ${ECHO_CMD} "removing, and modifying printer queues." 
        ${ECHO_CMD}
        ${ECHO_CMD} "To set the administrative group, select any valid group."
        ${ECHO_CMD} "The default is ( ${DEF_GROUP} )."
        ${ECHO_CMD}

        continue=yes
    
        app_group="`get_value app.group`"
        if [ "${?}" = "0" ];then
            GROUP="${app_group}"
        else
            GROUP="${DEF_GROUP}"
        fi
    
        while [ "${continue}" = "yes" ]
        do
            ${PRINTF_CMD} "Enter an administrative group ( ${GROUP} ): "
            read mvgroup
            if [ -z "${mvgroup}" ]; then
                mvgroup="${GROUP}"
            fi
            check_group ${mvgroup}

                continue=no
            fi
