Unix/Linux/MacOSx : How to remove an environment variable ?

Somehow I screwed up my GOPATH and GOROOT environment variables today and removing (sudo yum remove ) Go did not help. A quick check revealed the old environment variables are still around.

Problem :

How to remove the unwanted environment variables ?

Solution :

Use unset command. unset <environment variable>

For example :

unset GOROOT
