My master plan is to be able to send CEC commands from my raspberry pi to do things such as turn on/off the tv as well as other devices connected to the TV. Then I will be adding voice recognition to send these commands...that's for another day. I have read up on CEC but from what I've gathered it seems like you can't send CEC commands directly through the command line without the CEC usb adapter? I have installed the cec-client and libCEC library on my pi but when I run cec-client -l it shows no devices.
My question is, how can I send CEC commands via the command line to my tv from the pi without the adapter? Am I missing some basic element about CEC?
UPDATE
In addition to the posts below here is a link that asked in the PI portion of stackoverflow which has some more CEC commands that I have put within my .bashrc to turn the tv on/off and change the input

Recent versions of libcec will recognize the Raspberry Pi hardware as a CEC adapter.
To send control commands through the command line, basically:
echo "on 0" | cec-client -s
will power on device 0 (ie your TV)
Check out cec-client interactive shell for more complex commands
