I am new to shell scripting so I am curious about using While Loops in Shell Script form.

I know how to declare a variable and use a while loop in java

int num = 0;

while(num <= 10)

{

    System.out.println(num)

    num = num + 1

}

But I don't know how to declare variables and use them in a while loop in a Shell Script.

You'll be much happier using a for loop instead (according to your example)

for i in {0..10}; do

    echo "$i"

done

If you must use a while loop, consider the following

i=0

while [[ $i -le 10 ]]; do

    echo "$i"

    i=$((i+=1))

done
