使用基于环境变量的路径运行脚本

Question

我将环境变量artemis_home设置为C:\artemis。

PS C:\artemis_brokers> $env:ARTEMIS_HOME
C:\artemis

在这个目录下，我有一个名为bin的文件夹，它包含一个artemis.cmd脚本。如何使用system变量从PowerShell中的任何地方运行此脚本？

我尝试过以下方法，但没有成功：

PS C:\artemis_brokers> $env:ARTEMIS_HOME/bin/artemis
At line:1 char:19
+ $env:ARTEMIS_HOME/bin/artemis
+                   ~
You must provide a value expression following the '/' operator.

在尝试执行之前，您需要展开该变量并将路径的其余部分串联成一个字符串。要执行结果字符串，请使用&，即调用运算符：

& "$env:ARTEMIS_HOME/bin/artemis.cmd"
