PowerShell 类似于“dir /a:d” (Win) 或“ls -d */” （重击）

我只想使用 PowerShell 列出当前工作目录下的所有目录。这在 Bash shell

ls -d */

或 Windows 中的 cmd.exe

dir /a:d

中很容易实现：使用 PowerShell，但是我似乎无法使用单个命令来完成此操作。相反，我发现唯一有效的是：

ls | ? {$_Mode -like "d*"}

这似乎太冗长和复杂，而且我怀疑我不需要一个单独的Where子句。不过，Get-ChildItem 的帮助并没有明确说明如何过滤模式。谁能启发我吗？

原文

I simply want to list all of the directories under my current working directory, using PowerShell. This is easy from a Bash shell:

ls -d */

or cmd.exe in Windows:

dir /a:d

Using PowerShell however I cannot seem to be able to do it with a single command. Instead the only the I've found that works is:

ls | ? {$_Mode -like "d*"}

That seems way too wordy and involved, and I suspect that I don't need a separate Where clause there. The help for Get-ChildItem doesn't make it clear how to filter on Mode though. Can anyone enlighten me?

这也有效：

ls | ?{$_.PsIsContainer}

毫无疑问，它比 bash 或 cmd.exe 更冗长一些。如果您想减少冗长，您当然可以在您的配置文件中添加一个函数和一个别名。我会看看是否能找到一种使用 -filter 的方法。

经过进一步调查，我认为除了创建自己的函数和别名之外，没有更简洁的方法可以做到这一点。您可以将其放入您的个人资料中：

function Get-ChildContainer
{
    param(
            $root = "."
          )
    Get-ChildItem -path $root | Where-Object{$_.PsIsContainer}
}

New-Alias -Name gcc -value Get-ChildContainer -force

然后将 ls 文件夹中的目录：

gcc C:\

此解决方案会受到一些限制，因为它无法处理任何花哨的内容，例如 -Include、-Exclude、-Filter、-Recurse 等，但您可以轻松地将其添加到函数中。

实际上，这是一个相当幼稚的解决方案，但希望如果您决定追求它，它将引导您走向正确的方向。老实说，我不会打扰你。在我个人看来，powershell 总体上更大的灵活性足以克服这种情况下的额外冗长。

This works too:

ls | ?{$_.PsIsContainer}

There is no doubt that it is a little more wordy than bash or cmd.exe. You could certainly put a function and an alias in your profile if you wanted to reduce the verbosity. I'll see if I can find a way to use -filter too.

On further investigation, I don't believe there is a more terse way to do this short of creating your own function and alias. You could put this in your profile:

function Get-ChildContainer
{
    param(
            $root = "."
          )
    Get-ChildItem -path $root | Where-Object{$_.PsIsContainer}
}

New-Alias -Name gcc -value Get-ChildContainer -force

Then to ls the directories in a folder:

gcc C:\

This solution would be a little limited since it would not handle any fanciness like -Include, -Exclude, -Filter, -Recurse, etc. but you could easily add that to the function.

Actually, this is a rather naive solution, but hopefully it will head you in the right direction if you decide to pursue it. To be honest with you though I wouldn't bother. The extra verbosity in this one case is more than overcome by the overall greater flexibility of powershell in general in my personal opinion.
