Try the following:
:new
:0r !set
(with a space before the exclamation mark). In some shells, including
(but not necessarily limited to) command.com, cmd.exe and bash, this
will answer your question. It should show you the environment Vim passes
to the processes it spawns, most of which it will have inherited from
whatever shell or window-manager launched it.
Another possibility (to get the names but not the values) is
:echo $^D
where ^D means "hit Ctrl-D".
Best regards,
Tony.
