PowerShell 的 Get-ChildItem cmdlet 可能返回哪些“模式"值? [英] What are the possible 'Mode' values returned by PowerShell's Get-ChildItem cmdlet?

问题描述

当我在目录上运行 PowerShell 的 Get-ChildItem 时(或任何返回文件系统项的 cmdlet)，它会显示一个名为 Mode 的列，如下所示:

When I run PowerShell's Get-ChildItem on a directory (or any cmdlet that returns file system items), it shows a column called Mode, like this:

    Directory: C:\MyDirectory


Mode                LastWriteTime     Length Name
----                -------------     ------ ----
d----          2/8/2011  10:55 AM            Directory1
d----          2/8/2011  10:54 AM            Directory2
d----          2/8/2011  10:54 AM            Directory3
-ar--          2/8/2011  10:54 AM        454 File1.txt
-ar--          2/8/2011  10:54 AM       4342 File2.txt

我搜索并搜索了 Google 和我本地的 PowerShell 书籍，但找不到任何关于 Mode 列含义的文档.

I searched and searched Google and my local PowerShell book, but I could not find any documentation on the meaning of the Mode column.

Mode 列的可能值是什么，每个值的含义是什么?

推荐答案

请注意，您看到的模式只是位域 enum 的字符串表示，它隐藏在属性 属性.您只需将两个字母并排显示即可了解各个字母的含义:

Note that the mode you see is just a string representation of a bitfield enum that hides in the Attributes property. You can figure out what the individual letters mean by simply showing both side by side:

PS> gci|select mode,attributes -u

Mode                Attributes
----                ----------
d-----               Directory
d-r---     ReadOnly, Directory
d----l Directory, ReparsePoint
-a----                 Archive

无论如何，完整列表是:

In any case, the full list is:

d - Directory
a - Archive
r - Read-only
h - Hidden
s - System
l - Reparse point, symlink, etc.
