fbgrab: Takes a screenshot using the framebuffer device

fbgrab is a wrapper around fbcat which emulates the behaviour of Gunnar Monell's fbgrab utility.

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

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.

The following options of Gunnar Monell's fbgrab are recognized but not supported:
