可以从https://goprogram.co.uk/software/commands安装which命令，以及所有其他UNIX命令。

看看这个PowerShell哪个。

这里提供的代码表明:

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

在Windows 2003或更高版本(或Windows 2000/XP，如果您已经安装了Resource Kit)上尝试使用where命令。

顺便说一下，这个问题在其他问题中得到了更多的答案:

Windows上有对应的“which”吗?

PowerShell相当于Unix的哪个命令?

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 }
        }
    }

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}
