Process environment
extern char **environ;
environ is an array of strings, called the environment of a
process. By convention, each string has the form
name=value
Normally, each process inherits the environment of its parent
process. The shell sh and various forms of exec can change the
environment. The shell adds the name and value of each shell
variable marked for export to the environment of subsequent com-
mands. The shell adds assignments given on the same line as a
command to the environment of the command, without affecting sub-
sequent commands.
