NAME

screendump - dump the contents of a virtual console to stdout

SYNOPSIS

screendump [,options/] [,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.

OPTIONS

-V, --version: print version number.
-h, --help: print this usage message.

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.
