Until loop

For completeness, we have included the until loop. It is not used very often and is almost the same as a do while loop. Notice that its condition and operation is consistent with incrementing a counter until a value is reached:

#!/bin/bash
CTR=1
until [ ${CTR} -gt 9 ]
do
    echo "CTR var: ${CTR}"
    ((CTR++)) # Increment the CTR variable by 1
done
echo "Finished"
