Why has the result? 为什么会有结果呢？ I just want to >> the call result to log file. 我只想>>将调用结果发送到日志文件。

Answer 1

try this to avoid trailing spaces in %logdir% : 尝试这样做以避免%logdir%尾随空格：

set "logdir=d:\ora\log"
>>"%logdir%\hot_gen%date:~0,4%%date:~5,2%%date:~8,2%.log" call d:\Hot_gen.bat %B_SCRIPT_TARGET% %B_BACKUP_TARGET%

Answer 2

The value of the environment variable logdir has a space at the end. 环境变量logdir的值在logdir有一个空格。

This is most likely because you've got a line somewhere that says 这很可能是因为你在某个地方有一条线说

 set logdir=d:\ora\log

and there's an extra space at the end of the line. 并且在行尾有一个额外的空间。
