Question
Write a script to print numbers 5,4,3,2,1 using the while loops?
Answers
The algorithm for writing such a script would be:

- Begin value of i is set to 5.
- The while loop is started.
- Check of the value of i is zero. In case it is it will end the program and give the output.
- In case, the i is not equal to zero the value of i will be printed and the i's value is decremented by 1.

The code:

i=5
while test $i != 0
do
echo "$i"
i=`expr $i - 1`
done   Your Comment
