There is an array called env that stores all the environment variables. So you can simply do this:

puts [array get env]

or simply

parray env

The difference between the two is that parray sorts the keys, does nice indentation, and otherwise generally makes the output easy to read. array get doesn't; it's intended mainly for serialization of an array's data (ready to use with array set).

puts [array get env] - for me this prints nothing at all ?
