for (( expr1 ; expr2 ; expr3 )) ; do list ; done
First, the arithmetic expression expr1 is evaluated
according to the rules described below under ARITH-
METIC EVALUATION. The arithmetic expression expr2
is then evaluated repeatedly until it evaluates to
zero. Each time expr2 evaluates to a non-zero
value, list is executed and the arithmetic expres-
sion expr3 is evaluated. If any expression is
omitted, it behaves as if it evaluates to 1. The
return value is the exit status of the last command
in list that is executed, or false if any of the
expressions is invalid.

With best wishes,
