You'll get the exact same behavior with other programs like echo: $ echo \"NOS-CAFE DA MARINA\" "NOS-CAFE DA MARINA" $ echo '"NOS-CAFE DA MARINA"' "NOS-CAFE DA MARINA" wpa_cli does try to parse together the value from multiple command line arguments, but it does not get knowledge of what kind of whitespace was used between them, so it cannot build the correct value in some cases. Providing the full value as a single command line argument (like that second echo example above) is a more robust way of doing this. -- Jouni Malinen PGP id EFC895FA _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
