Thread: How to get RAW pixel data of screen to text file.

hi, i'm trying find simple way raw pixel data, or image of screen. example, can run cat /dev/input0 (to mouse coordinates) or cat /dev/video0 (to webcam video). i've tried run cat /dev/nvidia0 wont work. other ways can done?

hi,
think talking > operator.
eg: if want put output of ls command in file new.txt

code:

ls > new.txt

this delete if present in file.
if want append contents of file
use

code:

ls >> new.txt
