#!/bin/bash

# A simple bash "for loop" example below...
# This loop will run 5 times, and will echo the number in sequence as it goes.
# Mind the double . between the {}
# Note how the variable is called with the $ prefix, which can be done within the "" quotes!

for i in {1..5}
do
   echo "This is loop number $i"
done

# To achieve the same in a single line is also simple

for i in {1..5};do echo "this is loop number $i";done
