class ENV

ENV is a hash-like accessor for environment variables.

Interaction with the Operating System¶ ↑

The ENV object interacts with the operating system’s environment variables:

• When you get the value for a name in ENV, the value is retrieved from among the current environment variables.

• When you create or set a name-value pair in ENV, the name and value are immediately set in the environment variables.

• When you delete a name-value pair in ENV, it is immediately deleted from the environment variables.
