Writing a bash for-loop with a variable top-end

Question

I frequently write for-loops in bash with the well-known syntax:

for i in {1..10}  [...]

Now, I\'m trying to write one where the top is def

Answer 1

You can use for loop like this to iterate with a variable $TOP:

for ((i=1; i<=$TOP; i++))
do
   echo $i
   # rest of your code
done
