FBCAT(1) fbcat manual FBCAT(1)NAME
fbcat - takes a screenshot using the framebuffer device
SYNOPSIS
fbcat [fbdev]
DESCRIPTION
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.

fbgrab - takes a screenshot using the framebuffer device

DESCRIPTION
fbgrab is a wrapper around fbcat which emulates the behaviour of Gunnar Monell's fbgrab utility.
OPTIONS
fbgrab accepts the following options:
-c N
Grab the /dev/ttyN virtual terminal.
Note
This option might require root privileges (or CAP_SYS_TTY_CONFIG capability).

Note
This option might require root privileges (or CAP_SYS_TTY_CONFIG capability).
-d fb-device

By default, the device name is taken from the FRAMEBUFFER environment variable. If it is unset or empty, the default is /dev/fb0.
-i
Enable PNG interlacing.
-s N
Sleep N seconds before making the screenshot or switching virtual terminals.
-?
Display help and exit.
