A small work around to make the line blink in bash script

for (( i=0;i<=3;i++))
do
#Below line will deleted the before printed line
echo -en "\033[1A"
echo -en "EmpNo:$empno already exists\n";
sleep 0.4s;
#Below line to print a blank line
echo -en "\033[1A"
echo -en "                                                            \n";                                                                         
sleep 0.2s;
done
echo -en "\033[2A"
echo -en "                                                            \n";
echo -en "\033[1A"
echo -en "Enter the empno       : "; read empno1;
