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。

#>
param(

)
$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
