networking - How to add new network block to wpa_supplicant in command line? - Ask Ubuntu

i want add network block /etc/wpa_supplicant/wpa_suppplicant.conf file.

the original file looks like,

ctrl_interface=dir=/var/run/wpa_supplicant group=netdev update_config=1  network={     ssid="homewifi"     psk="12345678" } 

and add new network block in command line, file :

ctrl_interface=dir=/var/run/wpa_supplicant group=netdev update_config=1  network={     ssid="homewifi"     psk="12345678" }  network={     ssid="new_wifi"     psk="00000000" } 

i want not manual, command line.

i red https://wiki.archlinux.org/index.php/wpa_supplicant this, if run

# wpa_supplicant -b -i interface -c /etc/wpa_supplicant/wpa_supplicant.conf # wpa_cli  > scan ok > scan_results > add_network 0 > set_network 0 ssid "new_wifi" > set_network 0 psk "0000000" > enable_network 0 ctrl-event-connected - connection completed. > save_config ok 

will add new network block successfully.

but believe there more easy , simple way. above way takes time, , looks verbose. there more elegant , simple way it?
