我有这个高级功能在我的PowerShell配置文件:

    function which {
    <#
    .SYNOPSIS
    Identifies the source of a PowerShell command.
    .DESCRIPTION
    Identifies the source of a PowerShell command. External commands (Applications) are identified by the path to the executable
    (which must be in the system PATH); cmdlets and functions are identified as such and the name of the module they are defined in
    provided; aliases are expanded and the source of the alias definition is returned.
    .INPUTS
    No inputs; you cannot pipe data to this function.
    .OUTPUTS
    .PARAMETER Name
    The name of the command to be identified.
    .EXAMPLE
    PS C:\Users\Smith\Documents> which Get-Command
    
    Get-Command: Cmdlet in module Microsoft.PowerShell.Core
    
    (Identifies type and source of command)
    .EXAMPLE
    PS C:\Users\Smith\Documents> which notepad
    
    C:\WINDOWS\SYSTEM32\notepad.exe
    
    (Indicates the full path of the executable)
    #>
        param(
        [String]$name
        )
    
        $cmd = Get-Command $name
        $redirect = $null
        switch ($cmd.CommandType) {
            "Alias"          { "{0}: Alias for ({1})" -f $cmd.Name, (. { which $cmd.Definition } ) }
            "Application"    { $cmd.Source }
            "Cmdlet"         { "{0}: {1} {2}" -f $cmd.Name, $cmd.CommandType, (. { if ($cmd.Source.Length) { "in module {0}" -f $cmd.Source} else { "from unspecified source" } } ) }
            "Function"       { "{0}: {1} {2}" -f $cmd.Name, $cmd.CommandType, (. { if ($cmd.Source.Length) { "in module {0}" -f $cmd.Source} else { "from unspecified source" } } ) }
            "Workflow"       { "{0}: {1} {2}" -f $cmd.Name, $cmd.CommandType, (. { if ($cmd.Source.Length) { "in module {0}" -f $cmd.Source} else { "from unspecified source" } } ) }
            "ExternalScript" { $cmd.Source }
            default          { $cmd }
        }
    }

还有使用which的选项。实际上有三种方法可以从Windows powershell中访问

第一个(虽然不是最好的)是wsl(linux的windows子系统)

wsl -e which command 

这需要安装Linux的windows子系统和一个正在运行的发行版。

下一个是gnuwin32，它是几个。exe格式的gnu二进制文件的移植，作为独立的捆绑启动程序 第三，安装msys2(跨编译器平台)，如果你去/usr/bin中安装它，你会发现很多很多最新的gnu utils。他们中的大多数工作作为独立的exe，可以从bin文件夹复制到你的家庭驱动器的某个地方，并添加到你的路径。

我对Which函数的命题是:

function which($cmd) { get-command $cmd | % { $_.Path } }

PS C:\> which devcon

C:\local\code\bin\devcon.exe

这似乎是你想要的(我在http://huddledmasses.org/powershell-find-path/):上找到了它

Function Find-Path($Path, [switch]$All = $false, [Microsoft.PowerShell.Commands.TestPathType]$type = "Any")
## You could comment out the function stuff and use it as a script instead, with this line:
#param($Path, [switch]$All = $false, [Microsoft.PowerShell.Commands.TestPathType]$type = "Any")
   if($(Test-Path $Path -Type $type)) {
      return $path
   } else {
      [string[]]$paths = @($pwd);
      $paths += "$pwd;$env:path".split(";")

      $paths = Join-Path $paths $(Split-Path $Path -leaf) | ? { Test-Path $_ -Type $type }
      if($paths.Length -gt 0) {
         if($All) {
            return $paths;
         } else {
            return $paths[0]
         }
      }
   }
   throw "Couldn't find a matching path of type $type"
}
Set-Alias find Find-Path

看看这个PowerShell哪个。

这里提供的代码表明:

($Env:Path).Split(";") | Get-ChildItem -filter notepad.exe

与Unix的快速匹配

New-Alias which where.exe

但如果它们存在，它会返回多行，然后它就变成

function which {where.exe command | select -first 1}
