如何在 PowerShell 中将环境变量打印到控制台? [英] How to print environment variables to the console in PowerShell?

问题描述

我开始使用 PowerShell 并试图弄清楚如何将系统环境变量echo 回显到控制台以读取它.

I'm starting to use PowerShell and am trying to figure out how to echo a system environment variable to the console to read it.

以下都不起作用.第一个只打印 %PATH%，第二个什么都不打印.

Neither of the below are working. The first just prints %PATH%, and the second prints nothing.

echo %PATH%
echo $PATH

推荐答案

在变量名前加上 env:

$env:path

例如，如果要打印环境值MINISHIFT_USERNAME"的值，则命令为:

For example, if you want to print the value of environment value "MINISHIFT_USERNAME", then command will be:

$env:MINISHIFT_USERNAME

您还可以通过 env 驱动器枚举所有变量:

You can also enumerate all variables via the env drive:

Get-ChildItem env:
