Hello Thomas,

Sorry for the long time without a reply. I just forgot about it and stumbled upon it right now.

I'm using strongSwan 5.2.0,

"ipsec stroke -- loglevel any" doesn't work and returns  status 2 and
"/usr/bin/ipsec: unknown option `--' (perhaps command name was omitted?)"
on stdout. "ipsec stroke loglevel any _1" works just fine.

I don't understand why _1 works.
Also, I don't work with the getopt library and have no idea how it works internally.
 always write my own input validation code.

Mit freundlichen Grüßen/Regards,
Noel Kuntze
