我如何问PowerShell的东西在哪里?

例如,"which notepad",它根据当前路径返回notepad.exe运行的目录。

如果你有勺子,你可以安装一个直接克隆:

scoop install which
which notepad

看看这个PowerShell哪个。

这里提供的代码表明:

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

我通常只输入:

gcm notepad

or

gcm note*

gcm是Get-Command的默认别名。

在我的系统上,gcm note*输出:

[27] » gcm note*

CommandType     Name                                                     Definition
-----------     ----                                                     ----------
Application     notepad.exe                                              C:\WINDOWS\notepad.exe
Application     notepad.exe                                              C:\WINDOWS\system32\notepad.exe
Application     Notepad2.exe                                             C:\Utils\Notepad2.exe
Application     Notepad2.ini                                             C:\Utils\Notepad2.ini

您将获得与您正在查找的内容相匹配的目录和命令。

如果你有勺子,你可以安装一个直接克隆:

scoop install which
which notepad

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 }
        }
    }

试试这个例子:

(Get-Command notepad.exe).Path
