Question

我想执行一个驻留在script.ps1文件旁边的program.exe ... 我怎样才能获得这个位置/文件夹？（这不是固定的位置/文件夹，可以是USB棒或网络驱动器等）

我尝试过使用

$MyInvocation.MyCommand.Path

但它似乎没有帮助我（或者我没有以严格的方式使用它）

由于

Answer 1

这是我通常使用的模式：

$exeName        = "MyApplication.exe"
$scriptFolder   = Split-Path -Parent $MyInvocation.MyCommand.Path
$exeFullPath    = Join-Path -Path $scriptFolder -ChildPath $exeName

$MyInvocation是一个自动变量。

包含有关当前命令的信息，例如名称，参数，参数值以及有关命令的信息启动，调用或“调用”，例如脚本的名称称为当前命令。

请注意，$ MyInvocation.MyCommand返回的对象根据执行它的上下文而有所不同。

从powershell命令窗口返回类型 ScriptInfo ，注意缺少Path属性：

   TypeName: System.Management.Automation.ScriptInfo

从脚本运行时，类型为 ExternalScriptInfo ，请注意其他属性ScriptContents和Path等。
