I have seen the usage of %* in batch files and command lines. Googling did not give me any results. Can some one explain the typical usage of %* with an example.Thanks

推荐答案

这意味着在命令行中的所有参数。

It means "all the parameters in the command line".

例如，当你想通过命令行从您的批处理文件转发到另一个程序是非常有用的：

For example, it's useful when you want to forward the command line from your batch file to another program:

REM mybatchfile.cmd
echo You called this with arguments: %*
echo I will now forward these to the DIR command.
dir %*
