用于运行cmd.exe内置函数的PowerShell别名语法？ [英] PowerShell alias syntax for running a cmd.exe builtin function?

问题描述

由于我最近才从 cmd.exe 切换到PowerShell，所以我经常发现通过调用以熟悉的方式完成小事情很方便cmd 来完成它们。例如，要做一个裸露的文件列表，效果很好：

As I have only recently switched to PowerShell from cmd.exe, I often find it convenient to do little things in a familiar way by calling cmd to do them. For instance, to do a 'bare' file listing this works great:

PS> cmd /c dir /b
dir1
dir2
file1.txt

<我想为此起一个别名，但是我找不到正确的语法。到目前为止，我已经尝试过：

I'd like to make an alias for this but I can't figure out the right syntax. So far I've tried:

PS> Set-Alias dirb cmd /c dir /b        # error (alias not created)
PS> Set-Alias dirb "cmd /c dir /b"      # fail (alias doesn't work)
PS> Set-Alias dirb "cmd `"/c dir /b`""  # fail (alias doesn't work)

有什么建议吗？我正在寻找一种调用内置 cmd.exe 命令（例如 dir ）的常规解决方案。我也想知道如何使用PowerShell cmdlet以正确的方式产生裸露的输出，但这是目前的第二个问题。这个问题是关于从别名调用 cmd.exe 的正确语法的。

Any suggestions? I'm looking for a general solution to calling builtin cmd.exe commands (such as dir). I'd also like to know how to produce bare output the right way using PowerShell cmdlets, but that's a secondary concern at the moment. This question is about the proper syntax for calling cmd.exe from an alias.

推荐答案

我相信您想要的是一个函数，而不是别名。例如：

I believe what you want is a function, not an alias. For instance:

  function dirb {
    cmd /c dir $args[0] /b
     }

在PS提示符下，运行记事本$ profile，将其粘贴到您的个人资料中，然后它将自动加载当您打开PS控制台时，可以执行以下操作：

From a PS prompt, run notepad $profile, paste that into your profile and then it will load automatically when you open a PS console and you can do this:

dirb c：\somedir

dirb c:\somedir
