I want to update the server by using a batch file and

isql -i update.sql -o result.txt

By using this parameters I have a "Result.txt" file but size is 0 (zero) byte.
Output of isql is on screen.

How can I get the result of updates?
and, how can I sure that update is completed without any problem?

NOTE : I know you will say IBExpert free edition but, I need a compact utility size must not be more than ISQL's size.

Any suggestion.
