With "let ++var", the result is still 0, it isn't incremented. With $[++var], the result is "0: command not found". "$((++var))" is to the same effect as "let ++var". $((var+1)) works. But the value of var can't be incremented. thanks, Xu Qiang _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
