Описание (Description)

program_invocation_name contains the name that was used to invoke
       the calling program.  This is the same as the value of argv[0] in
       main(), with the difference that the scope of
       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.

Стандарты (Conforming to)

These variables are GNU extensions, and should not be used in
       programs intended to be portable.
