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