for i in  {0..10..5}
do
echo -e "Maharshi\t$i"
done

do
echo -e "Maharshi\t$i"
done

for i in {1..10}
do
printf "%s\n%s\n" "Galgotias" "UNiversity";
done


for i in $(seq 1 10)
do
printf "%s\n%s\n" "Galgotias" "UNiversity";
done


for i in $(seq 1 2 10)
do
printf "i is %d\n" "$i";
done

for i in $(seq 10 -2 1)
do
printf "i is %d\n" "$i";
done

for((i=4;i<10;i++))
do
echo "Maharshi";
done

echo "enter a number";
read number;
if (((number < 10))  &&  ((number > 1)))||(((number<100))&&((number>90)))
then
echo $number;
fi

i=0
while ((i < 5 ))
do
echo "maharshi";
i=$(($i+1));
done

arithmatic expansion

i=15;
i=$(($i*5));
echo $i;
