如何发送多个语句到同一个.cmd实例？ [英] How to send multiple statements to the same .cmd instance?

问题描述

如何发送多个命令到.cmd脚本的同一个实例？从cmd 或 powershell执行此操作是可以接受的。

How can I send multiple commands to the same instance of a .cmd script? Doing so from either cmd or powershell is acceptable.

我不是试图在单个连接语句中发送多个命令 - 字符限制可能是一个非常大的脚本的因素。相反，我想将多个命令作为单独的语句发送到正在运行的.cmd脚本。当我说.cmd，我不是指cmd.exe - 我的意思是一个自定义shell脚本，保存到磁盘与 .cmd extension。

I'm not trying to to send multiple commands in a single concatenated statement-- character-limits could be a factor with very large scripts. Rather, I want to send multiple commands, as separate statements, to a running .cmd script. When I say ".cmd", I do not mean "cmd.exe"-- I mean a custom shell script, saved to disk with a .cmd extension.

具体来说，此帖子演示如何创建powershell4.cmd脚本这将启动.Net 4.0 PowerShell。我想向该powershell发送一系列命令。

Specifically, this post shows how to create a powershell4.cmd script which launches a .Net 4.0 PowerShell. I want to send a sequence of commands to that powershell.

例如，是否可以获取该新shell的句柄，以向其发送其他命令？

For example, is it possible to get a handle to that new shell, in order to send additional commands to it?

推荐答案

另一种方法是将保存的命令保存到文件中（例如 test.in ）然后使用如下命令：

Another approach might be to put the save the commands you want to send in a file (e.g. test.in) and then use a command like this:

Start-Process -RedirectStandardInput test.in cmd 

考虑添加 -Wait 和 -NoNewWindow 。你需要实验一些，看看这如何与批处理脚本交互。

Consider adding -Wait and -NoNewWindow. You would need to experiment some to see how this interacts with a batch script.

我不相信PowerShell本身支持重定向到管道，但它可以通过调用.NET运行时来实现。

I don't believe PowerShell natively supports redirecting to a pipe, but it might be doable by calling the .NET runtime.
