While Loopsuggest change
#! /bin/bash i=0 while [ $i -lt 5 ] #While i is less than 5 do echo "i is currently $i" i=$[$i+1] #Not the lack of spaces around the brackets. This makes it a not a test expression done #ends the loop
Watch that there are spaces around the brackets during the test (after the while statement). These spaces are necessary.
This loop outputs:
i is currently 0 i is currently 1 i is currently 2 i is currently 3 i is currently 4
