从命令行列出所有环境变量？(List all environment variables from command line?)

从命令行列出所有环境变量？(List all environment variables from command line?)

我想知道是否可以从Windows命令行列出所有的环境变量。

相当于powershell gci env:或ls env: or dir env: gci env:东西。

I'd like to know if it's possible to list ALL environment variables from Windows' Command Prompt.

Something equivalent to PowerShell's gci env: (or ls env: or dir env:).

做就是了

SET

您也可以使用SET prefix查看名称以prefix开头的所有变量。

例如，如果您只想从环境变量中只读取derbydb，请执行以下操作：

set derby

您将得到以下内容：

DERBY_HOME=c:\Users\amro-a\Desktop\db-derby-10.10.1.1-bin\db-derby-10.10.1.1-bin

Just do:

SET

You can also do SET prefix to see all variables with names starting with prefix.

For example if you want to read only derbydb from the environment variables, do the following:

set derby

...and you will get the following:

DERBY_HOME=c:\Users\amro-a\Desktop\db-derby-10.10.1.1-bin\db-derby-10.10.1.1-bin
