Powershell Clear-Host替代方案可保留缓冲区 [英] Powershell Clear-Host alternative to preserve the buffer

问题描述

我想要类似Clear-Host的东西，但是想要回滚.

I would like something like Clear-Host, but would like the scrollback.

到目前为止，我所拥有的基本上只是添加换行符，直到屏幕清晰为止.虽然在执行此操作时，光标开始在页面底部开始书写(尽管不希望如此，这是可以预期的).

So far, all I have is basically adding newlines until the screen is clear. Though when I do this, the cursor starts writing at the bottom of the page (as to be expect- though not desired).

我希望从页面顶部开始写(对于菜单等，这是很自然的事情)

I would hope to start writing at the top of the page (for menus and such- which is the natural thing to do)

这是打印新行动态计数的代码:

This is the code to print the dynamic count of new lines:

do {Write-Host ""; $i++}
while ($i -ne $Host.UI.RawUI.WindowSize.Height)

我确实看到了有关Transcript模块的内容，但并不希望如此.

I did see something about a Transcript module, but do not desire that.

提前谢谢.
