You can't hook a file directly to stdin, but you can still access stdin.

您不能将文件直接挂接到stdin,但您仍然可以访问stdin。

For output redirection you can use:

对于输出重定向,您可以使用:

  command >  filename      Redirect command output to a file (overwrite)

  command >> filename      APPEND into a file

  command 2> filename      Redirect Errors 

Input redirection works in a different way. For example see this Cmdlet http://technet.microsoft.com/en-us/library/ee176843.aspx

输入重定向以不同的方式工作。例如,请参阅此Cmdlet http://technet.microsoft.com/en-us/library/ee176843.aspx
