112: Display Pi Camera Image over Mac Terminal/SSH
(simpler would be nice)

On the Pi install the feh command:


pi$ sudo apt-get update
pi$ sudo apt-get install feh

In Mac Terminal:

Find the name of your Pi with something like the "Ip Scanner" app.

mac$ ssh -X pi@yourPiName.local # Connect to the Pi using X11

Enable X11 file transfer on the Pi:

pi$ sudo nano /etc/ssh/ssh_config

Change this line:

#  ForwardX11 no
to:
ForwardX11 yes

Save and reboot the Pi.

Be sure XQuartz is running on the Mac -- then in Terminal (SSH as above) do:

pi$ feh yourImageFile

The image will display in a new Mac window. To get rid of it, type ESC. 

pi$ man feh

Will hint at how the feh command works.
