Yes, but SALT# wpa_cli set_network 23 ssid "NOS-CAFE DA MARINA" Selected interface 'wlan0' FAIL SALT# wpa_cli set_network 23 ssid \"NOS-CAFE DA MARINA\" Selected interface 'wlan0' OK This is slightly different from the echo example, echo accepts single quotes where wpa_cli appears to react differently. cheers ET > >> It feels like double spaces are somehow suppressed in wpa_cli > > wpa_cli does not do this, the shell command line parsing does..
