NAME
       fbgrab - takes a screenshot using the framebuffer device

SYNOPSIS
       fbgrab [option...] png-file

       fbgrab -?

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).

       -C N
	   Switch to the /dev/ttyN virtual terminal, then wait a few seconds before grabbing it.

	       Note
	       This option might require root privileges (or CAP_SYS_TTY_CONFIG capability).

       -d fb-device
	   Use the fb-device framebuffer 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.
