cmd中如何查看环境变量

查看所有环境变量

set

 

查看某一个环境变量

C:\WINDOWS\system32>set no_proxy
NO_PROXY=localhost,127.0.0.1,172.31.212.149

 

设置环境变量的值

As mentioned in other threads you can use set to list all the environment variables or use

set [environment_varible] to get specific variable with value.

set [environment_varible]= can be use to remove variable from space.
