Documentation

Copy the environment variable VARIABLE from the subshell to Emacs.

This command reads the value of the specified environment variable in the shell, and sets the same environment variable in Emacs
(what getenv in Emacs would return) to that value.
That value will affect any new subprocesses that you subsequently start from Emacs.

Probably introduced at or before Emacs version 20.1.
