program_invocation_name is global.
program_invocation_short_name contains the basename component of
name that was used to invoke the calling program. That is, it is
the same value as program_invocation_name, with all text up to
and including the final slash (/), if any, removed.
These variables are automatically initialized by the glibc run-
time startup code.
