Which part of the following doesn't work?

ctl()
{
    ERL_COMMAND=(
        "$ERL"
        "$NAME" ejabberctl
        -noinput
        -pa "$EJABBER_EBIN"
        -s ejabber_ctl -extra "$ERLANG_NODE" "$@"
    )
    W=`whoami`
    if [ "$W" != "ejabberd" ]; then
        /sbin/runuser -s /bin/bash - ejabberd -c "${ERL_COMMAND[@]}"
        result=$?
    else
        bash -c "${ERL_COMMAND[@]}"
        result=$?
    fi

    # replace remainder of function here
}
