Run a command

Problem

Use run to launch echo with two separate arguments: home: and $HOME. Let its output go to the screen. Notice that $HOME appears literally, and the home directory is not printed — because run does not involve a shell, there is no variable expansion.

Example

The program prints:

home: $HOME
