fbcat - takes a screenshot using the framebuffer device
fbcat [fbdev]
fbcat takes a screenshot using the framebuffer device. The produced image is in PPM format. Note that redirection of standard output to a file or another process is needed since fbcat will refuse to write it's output directly to the terminal.
