Please use code tags as required by forum rules!

man bash:
Quote:
for (( expr1 ; expr2 ; expr3 )) ; do list ; done
First, the arithmetic expression expr1 is evaluated according to the rules described below under ARITHMETIC EVALUATION. The arithmetic expression expr2 is then evaluated repeatedly until it evaluates to zero. Each time expr2 evaluates to a non-zero value, list is executed and the arithmetic expression expr3 is evaluated. If any expression is omitted, it behaves as if it evaluates to 1. The return value is the exit status of the last command in list that is executed, or false if any of the expressions is invalid.

Please, don't post screen shots/pictures, as they can't be used for further analysis. Post code or result lines within code tags.

for (( i=W_NO; i>=W_NO; i--)) will execute exactly zero times, as the ending condition is immediatedly met. You may have had i>=0 in mind?

Are you looking for something basic as:

Code:
printf "Please enter the number of loops: "
read number

C=0
while [ "$C" -lt "$number" ]
do	echo "Loop nr: $C"
	((C++))
done

Place your code inside the loop.
