NAME
screendump - dump the contents of a virtual console to stdout
SYNOPSIS
screendump
[
N
]
DESCRIPTION
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.
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.
