2. SYNOPSIS ▲
screendump [ N ]
3. DESCRIPTION ▲
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.
4. NOTES ▲
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.
