Answer 1

You can use SET in cmd

To show the current variable, just SET is enough

To show certain variable such as 'PATH', use SET PATH.

For help, type set /?.

Answer 2

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
