hello,
according to zshmisc(1):
- The command is executed with a `-' prepended to its argv[0] string.
ok ... but why is it useful?
regards,
marc

Most shells check whether their argv[0] starts with a "-", and if that's
the case, they behave as login shells (as though -l was passed).
The effect can also be achieved with ARGV0; see zshparam(1).
Cheers,
Daniel
