Connect to a hidden wireless by command line

[Marcelo Laia <marcelolaia@gmail.com>]

Hi,

I am in a hidden wireless network when I could connect in it set this
commands in /etc/network/interfaces:

auto wlan0
iface wlan0 inet static
wpa-driver wext
wpa-conf managed
wpa-ssid BLABLABLABLA
wpa-ap-scan 2
wpa-proto WPA RSN
wpa-pairwise TKIP CCMP
wpa-group TKIP CCMP
wpa-key-mgmt WPA-PSK
wpa-psk 350115281df535db8ddb500479b5101dc84ee597043f7d8e7f8b2437a214dee0
address 10.xxx.xxx.xxx
netmask 255.255.255.0
gateway 10.xxx.xxx.xxx

How I could do that by command line?

I need because I am very sad to need to change my interfaces all the
day! In my house I have an AP and I connect to it by NM. So, at night
I connect by NM and at morning I need to start my note, change
/etc/network/interfaces and restart the note!

Thank you very much!

Marcelo
