screendump − dump the contents of a virtual console to stdout
screendump [ N ]
The screendump command dumps the contents of virtual console N , (or the current console if N is omitted) to standard out.
Just saying
cat /dev/vcsN
has a similar effect.
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
cd /dev for i in 0 1 2 3 ...; do
|
mknod vcs$i c 7 $i | ||
|
mknod vcsa$i c 7 ’expr 128 + $i’ |
done
(filling in the ellipses) and give the device files appropriate permissions, or run screendump as root.
