Reset classpath

I ran export CLASSPATH=/home/del开发者_如何学JAVAtrem/jscheme/jscheme.jar, but now kawa, which was working, doesn't work any longer. Is there a way to revert the CLASSPATH?

I found it!

set CLASSPATH=

if you are using it from terminal you can close that terminal window and open a new one. or

export CLASSPATH=

export CLASSPATH=

Yes, it work in my environment (linux ubuntu 18.04).
