screendump [ N ]
The screendump command dumps the contents of virtual console N , (or the current console if N is omitted) to standard out.
For security reasons, screendump uses linux devices "virtual console screen" and "virtual console screen with attributes" to give access for screendump.
Ensure these files exist, using
(filling in the ellipses) and give the device files appropriate permissions, or run screendump as root.
