Connecting to wifi via command line.

[/RaspberryPi]

I am trying to configure my wifi connection and connect via the command line. I have gone into the /etc/wpa_supplicant/wpa_supplicant.conf file and added my wifi name and password and verified. But for the life of me, I can't connect to it.
network={
ssid=""
psk="
"
key_mgmt=WPA-PSK
}
I run
sudo iwconfig wlan0 essid key s:
followed by
sudo dhclient wlan0 Never connects. Just sits there and returns a command line like nothing happened.
Am I missing something? I had it working on Friday but had to blow it away for another issue. Now it won't.
