-------------------------------------------------------------------

In {{flink-daemon.sh}} the is the following piece of script:
{code}
        # Add to pid file if successful start
        if [[ ${mypid} =~ ${IS_NUMBER} ]] && kill -0 $mypid > /dev/null 2>&1 ; then
            echo $mypid >> $pid
        else
            echo "Error starting $DAEMON daemon."
            exit 1
        fi
{code}
Could it be changed with {{echo $mypid > $pid}} or it brake something?
