In languages like C and Java, if you want to run something 10 times you could write something like
for (int i = 0; i < 10; ++i) { ... }
You can do this in a number of ways in Bash, but one of the easiest ways is like this;

for i in {1..10}; do ... done

You can also change the step size by adding an extra number in the curly braces. So for example:

for i in {1..10..3}; do echo $i; done

will print
