dev$ ssh -p 1235 root@localhost "./can_rx | egrep 'O2|F1DF' " >> touchscreen_can_log.txt

This will log to dev data streamed from the touch screen via the shh tunnel.

# This assumes the reverse_tunnel.sh is running on the target touch screen

to get this running log in from dev
|

dev$ ssh -p1235 root@localhost
|
